Quick answer: Deux par Deux rates three of its kids' snowsuit lines to -30°C (-22°F). DISCOVER (sizes 2 to 8) suits daycare, preschool and everyday snow play. PLAY (sizes 2 to 14) adds backpack-style straps, articulated elbows and a neck warmer for school recess. TEKNIK (sizes 4 to 16) adds a 15,000 mm rating, PrimaLoftŽ insulation and ski-boot pant openings for skiing.
All three lines share the same -30°C (-22°F) warmth rating from Deux par Deux, so the choice is not about which suit is "warmer." It comes down to your child's age, how they spend their winter days and how wet the snow gets where you live. A fourth line, CHILL, is a lightweight two-piece that Deux par Deux rates to -5°C (23°F) for milder days, so it is not part of this comparison. This guide compares the lines side by side using the brand's own spec sheets and the live product pages, then matches each line to real routines: daycare drop-off, school recess, sledding hills and ski days. If you already know the size you need, you can shop Deux par Deux snowsuits and outerwear and filter by line.

What Is the Difference Between Deux par Deux DISCOVER, PLAY and TEKNIK?
The short version: DISCOVER is the core everyday snowsuit for younger kids, PLAY keeps the same warmth and adds features that help kids manage their own gear, and TEKNIK is the ski line with a higher waterproofness rating, PrimaLoftÂŽ insulation and taped seams. Deux par Deux publishes a comparison table for its kids' lines, and the rows below come from that table and the brand's technical spec lists.
| Spec (as listed by Deux par Deux) | DISCOVER | PLAY | TEKNIK |
|---|---|---|---|
| Age range | 2 to 8 years | 2 to 14 years | 4 to 16 years |
| One-piece or two-piece | Both | Both | Both |
| Warmth rating | -30°C / -22°F | -30°C / -22°F | -30°C / -22°F |
| Waterproofness (polyurethane coating) | 10,000 mm (two-piece); 5,000 mm on the one-piece spec sheet | 10,000 mm | 15,000 mm |
| Insulation | Polyester fill: hood 57 g, body 170 g, sleeves and legs 170 g | Polyester fill: hood 57 g, body 170 g, sleeves and legs 170 g | Recycled PrimaLoftÂŽ: hood 100 g, body 170 g, sleeves and legs 133 g |
| Taped seams at armholes, shoulders, hood and crotch | No | No | Yes |
| Backpack-style straps inside the coat | No | Yes | Yes |
| Articulated elbows and knees | Knees only | Yes | Yes |
| Polar fleece neck warmer included | No | Yes | Yes |
| Detachable hood, removable faux fur (by model) | Yes | Yes | Yes |
| "Grow with Me" extendable sleeves and pants | Yes | Yes | Yes |
| Zippered sleeve pocket | Yes | Yes | Yes |
| Adjustable pant opening for ski boots | No | No | Yes |
| CorduraÂŽ on high-wear areas | Yes | Yes | Yes |

Where do the specs change from one style to another?
A few details depend on the individual style, not just the line. The biggest one is the DISCOVER one-piece: the brand's comparison table lists 10,000 mm for the DISCOVER line, but its one-piece spec list shows a 5,000 mm coating. Product pages for individual DISCOVER one-pieces may list a different figure, so check the specific suit if waterproofness matters to you. Faux-fur trim is also "depending on model," and PLAY and TEKNIK two-piece pants list two zippered pockets, while the DISCOVER sets we carry use bib-style pants without pockets.
Two details are easy to miss. The current Deux par Deux table lists a zippered sleeve pocket on all three lines, not only TEKNIK, and the PLAY product pages at Jenni Kidz list an included polar fleece neck warmer, matching the brand table.
Which Deux par Deux Snowsuit Is Right for Daycare and Preschool?
For most kids aged 2 to 5, DISCOVER is the practical starting point. It carries the same -30°C rating as PLAY and TEKNIK, it comes in the sizes preschoolers wear (2 to 8), and it skips ski features that a daycare yard will never use.
Daycare days are about repetition: suit on, suit off, a nap, then suit on again. DISCOVER's two-piece sets are built around that. On the DISCOVER two-piece snowsuit in blue bear print, the product page lists bib-style snow pants with adjustable, detachable suspenders, ankle snow gaiters with rubberized elastic, an adjustable snow skirt on the jacket and 500-denier CorduraÂŽ on the legs and seat. The product page notes that the bib rises high, so snow stays out when a child flops into a drift.
The DISCOVER two-piece snow suit in blue and pink unicorn print uses the same build: fleece lining in the jacket and bib, polyester fill rated to -30°C (-22°F), a detachable hood with removable faux fur, and VelcroŽ cuff tabs. Both product pages list a 10,000 mm polyurethane coating and the same "Grow with Me" details: sleeves that extend 4 cm (1.5 in) and a VelcroŽ hem that adds 5.7 cm (2 1/4 in).
Why does DISCOVER work so well for younger kids?
It covers the basics daycare staff ask for without adding parts to lose. There are no pant pockets to fill with snow, no separate ski-boot cuffs to adjust and no neck warmer to track. The Canadian Paediatric Society (CPS) recommends a neck warmer instead of a scarf and mitten clips instead of a string for younger children, so if you choose DISCOVER, plan to add a neck warmer and mitten clips from kids' winter accessories separately.
When should a preschooler skip DISCOVER?
Skip DISCOVER if your child is already close to size 7 or 8. DISCOVER stops at size 8, while PLAY runs to 14. A child who wears a 7 this year will likely need a PLAY or TEKNIK suit next year anyway, and the extendable sleeves and hems only stretch a suit's life so far. Siblings close in age can also wear different lines: a 3-year-old in DISCOVER and a 7-year-old in PLAY is a common split.

Which Line Fits School Recess and the Walk to School?
PLAY is built for the school-age routine. Deux par Deux rates it to the same -30°C (-22°F) as DISCOVER with the same insulation weights, but adds articulated elbows (DISCOVER articulates the knees only), integrated backpack-style straps inside the jacket and an included polar fleece neck warmer.
The PLAY two-piece snowsuit with dinosaur-print pants shows the line's school-day features in one set. Its product page lists a 10,000 mm polyurethane-coated shell, polyester fill rated to -30°C (-22°F), a detachable hood that adjusts at the back, 500D CorduraŽ at the knees, seat and hems, and a jacket, snow pants and polar fleece neck warmer included. The two-level hem adds 7.6 cm (3 in), slightly more than DISCOVER's VelcroŽ hem.
If your child prefers one piece, the PLAY one-piece snowsuit in navy floral print lists the same 10,000 mm coating and warmth rating, plus an adjustable interior waist, inner stretch cuffs, backpack-style straps, a zippered ski-pass sleeve pocket and an included polar fleece neck warmer. Sizes run from 2 to 14 on both PLAY styles.
How do PLAY's backpack-style straps help at school?
They let kids carry their own coat. Deux par Deux describes the straps as integrated into the back interior of the jacket, so a child can wear the coat like a backpack when they get warm indoors, on a field trip or in the hallway before recess. That can mean fewer coats left on the floor, and kids get one more thing they can handle on their own.
Is PLAY warmer than DISCOVER?
No. Deux par Deux lists identical insulation for both lines (57 g in the hood, 170 g in the body, sleeves and legs) and the same -30°C (-22°F) rating. What PLAY adds is mobility and convenience: articulation at the elbows as well as the knees, backpack straps, an included neck warmer and a size range that continues to 14.
Which Line Should You Choose for Sledding and Long Snow Days?
For an afternoon on the toboggan hill, DISCOVER and PLAY both do the job in dry, cold snow. TEKNIK starts to make sense when the snow is wet, your child spends hours outside, or they sit and kneel in snow for long stretches, because it has the higher 15,000 mm rating and taped seams at the armholes, shoulders, hood and crotch.
Sledding is hard on knees and seats. All three lines use CorduraÂŽ reinforcement at the knees, seat and pant hems, according to the Deux par Deux comparison table, so durability on the hill is similar across lines. The differences show up in how long a suit stays dry in heavy, wet snow, which is where the 10,000 mm versus 15,000 mm ratings and TEKNIK's sealed seams matter.
The CPS lists a few sledding habits worth teaching no matter which suit your child wears: children under 5 should never go down a hill alone, kids should always sit up or kneel on a sled rather than lie down, and they should slide down the middle of the hill and climb up along the sides. The CPS also suggests regular indoor breaks for younger children and removing wet clothing and boots right after playing.
Does a higher waterproofness rating matter for snow play?
It matters most in wet conditions. Deux par Deux gives waterproofness in millimetres, and the higher number is its more water-resistant fabric. In coastal or southern regions where winter means slush and rain, the 15,000 mm TEKNIK shell and taped seams give more margin. In cold, dry climates, a 10,000 mm DISCOVER or PLAY suit is often plenty. For a plain-English explanation of millimetre ratings and breathability numbers, see our guide to snowsuit warmth ratings explained.
Is TEKNIK Worth It for Skiing and Snowboarding?
Yes, if your child skis or snowboards regularly. TEKNIK is the only one of the three lines with an adjustable pant opening for ski boots, taped seams at critical areas and recycled PrimaLoftÂŽ insulation, which Deux par Deux describes as thin, warm and movement-friendly. It also carries the highest waterproofness rating at 15,000 mm.
The TEKNIK two-piece snowsuit in black, beige and burgundy lists recycled PrimaLoftÂŽ (100 g hood, 170 g body, 133 g sleeves and legs), seams sealed at the armholes, shoulders, hood and crotch, an adjustable snow skirt, a sleeve ski-pass pocket, built-in backpack straps and snow pants with removable suspenders, two zippered side pockets and adjustable ski-boot cuffs. Sizes run from 4 to 16.
For a one-piece option, the TEKNIK one-piece snowsuit in bright pink lists the same 15,000 mm coating and PrimaLoftÂŽ insulation, plus an interior adjustable waist, adjustable ankle snow guards with snaps and rubberized elastic, and CorduraÂŽ at the knees, seat and hems. It also runs from size 4 to 16.
What does TEKNIK add that a skier will notice?
Three things stand out on the hill. First, the adjustable pant opening is made to fit over ski boots, which DISCOVER and PLAY do not list. Second, the seams at the armholes, shoulders, hood and crotch are taped. Third, the PrimaLoftÂŽ insulation is lighter in the sleeves and legs (133 g versus 170 g on DISCOVER and PLAY), which Deux par Deux describes as easier to move in. TEKNIK also includes a polar fleece neck warmer.
When is TEKNIK more than you need?
If your child never skis and mostly plays at school or in the backyard, TEKNIK's ski-boot cuffs and sealed seams add cost without changing their day. The warmth rating is the same as PLAY's. In that case PLAY covers the same sizes up to 14 with the same backpack straps and neck warmer. TEKNIK is also not made in sizes 2 or 3, so toddlers start in DISCOVER or PLAY.
How Do Age Ranges and Sizes Narrow Your Choice?
Age range often makes the decision for you. Deux par Deux lists DISCOVER for ages 2 to 8, PLAY for 2 to 14 and TEKNIK for 4 to 16. A 2- or 3-year-old can choose between DISCOVER and PLAY. A 9- to 14-year-old chooses between PLAY and TEKNIK. A teen in size 16 is in TEKNIK only.
- Sizes 2 to 3: DISCOVER or PLAY
- Sizes 4 to 8: all three lines
- Sizes 9 to 14: PLAY or TEKNIK
- Size 16: TEKNIK
Deux par Deux recommends choosing the size its size guide suggests for your child's measurements and does not recommend buying a size up, because, in the brand's words, only the right size lets a child move comfortably and stay warm. The "Grow with Me" sleeves and hems on all three lines are there to add a season of wear instead. For step-by-step measuring, read our snowsuit sizing guide for babies, toddlers and big kids, and for a deeper look at the brand's fit and features, see our complete Deux par Deux snowsuit guide.
What about babies under 2?
DISCOVER, PLAY and TEKNIK are kids' lines. Deux par Deux makes separate baby lines, including Baby PLAY, with their own sizes and specs, so a baby snowsuit should be compared against the brand's baby table rather than this one.

Should You Pick a One-Piece or Two-Piece Within Each Line?
All three lines come in both styles, so you can pick the line first and the style second. A one-piece leaves no gap at the waist and is quick for younger kids in deep snow. A two-piece lets older kids wear the jacket alone on milder days and take the pants off more easily at school.
Within each line, the spec lists are close but not identical. Deux par Deux's DISCOVER one-piece spec sheet lists a 5,000 mm coating against 10,000 mm for the two-piece, while PLAY and TEKNIK list the same rating for both styles (10,000 mm and 15,000 mm). The PLAY and TEKNIK one-piece spec lists include an adjustable interior waist and inner stretch cuffs. Our one-piece vs two-piece snowsuit guide walks through the trade-offs in detail. To browse by style, see one-piece snowsuits or two-piece snowsuits and snow suit sets.
What Should Kids Wear Under a Deux par Deux Snowsuit?
A thin base layer, then adjust. Deux par Deux recommends thermal underwear under its snowsuits and says wearing cotton directly against the skin is not recommended in winter. The American Academy of Pediatrics (AAP) says several thin layers help keep kids warm and dry, and that insulated boots, mittens or gloves, and a hat are essential.
The CPS offers a simple check: if your child's hands and feet are warm, what they are wearing is usually enough. If they are dressed too warmly, they can sweat and then feel colder when they stop playing. That matters most for PLAY and TEKNIK kids who run hard at recess or ski all morning. Start with a base layer from kids' base layers, add a light fleece only on the coldest days, and finish with mittens from kids' mittens and gloves. The CPS recommends mittens instead of gloves so fingers can bunch together for warmth. For more layering ideas, see our layering guide for changing weather.
How Cold Is Too Cold to Play Outside, Even in a -30°C Snowsuit?
A snowsuit's warmth rating is not a green light to stay outside at that temperature. The AAP says playing outside in temperatures or wind chills below -15°F (about -26°C) should generally be avoided, because exposed skin begins to freeze within minutes. The CPS suggests keeping children indoors when the temperature or wind chill is -27°C (-16°F) or lower.
Faces, ears, fingers and toes are not covered by a snowsuit. The AAP notes that children lose heat more quickly than adults because their bodies are smaller, and that kids having fun may not come inside when they are getting too cold. Set time limits, plan indoor breaks and change out of wet clothes right away, whichever line your child wears.
Can Kids Wear a DISCOVER, PLAY or TEKNIK Snowsuit in a Car Seat?
No. The AAP's winter car seat guidance says bulky clothing, including winter coats and snowsuits, should not be worn underneath the harness of a car seat. In a crash, the padding flattens and leaves extra space under the straps. This applies to DISCOVER, PLAY and TEKNIK equally.
The AAP suggests dressing kids in thin layers for the ride, tightening the harness until you cannot pinch the strap at the chest, and then putting the winter coat on backwards over the buckled harness or laying a blanket over the straps. For the full step-by-step, see our guide can kids wear a snowsuit in a car seat?

Frequently Asked Questions About DISCOVER, PLAY and TEKNIK
What is the main difference between Deux par Deux PLAY and TEKNIK?
Deux par Deux rates both to -30°C (-22°F). TEKNIK adds a 15,000 mm waterproofness rating (PLAY lists 10,000 mm), recycled PrimaLoftŽ insulation, taped seams at the armholes, shoulders, hood and crotch, and an adjustable pant opening for ski boots. PLAY runs to size 14; TEKNIK runs from 4 to 16.
Is Deux par Deux DISCOVER less warm than PLAY?
No. Deux par Deux lists the same insulation for DISCOVER and PLAY (57 g hood, 170 g body, 170 g sleeves and legs) and the same -30°C (-22°F) rating. PLAY adds backpack-style straps, articulated elbows and an included neck warmer.
Which Deux par Deux snowsuit is better for daycare?
DISCOVER is a practical choice for daycare and preschool. It comes in sizes 2 to 8, carries the -30°C rating, and the two-piece sets we carry use bib snow pants with ankle snow gaiters. PLAY also starts at size 2 if you want backpack straps and a neck warmer included.
Do PLAY snowsuits come with a neck warmer?
Yes. The Deux par Deux comparison table lists a polar fleece neck warmer included with PLAY and TEKNIK, and the PLAY product pages at Jenni Kidz list an included polar fleece neck warmer. DISCOVER does not include one.
Is TEKNIK worth it if my child does not ski?
Usually not. TEKNIK has the same -30°C rating as PLAY. Its extras, like ski-boot pant openings and taped seams, matter most for skiing, snowboarding and long days in wet snow. For school and backyard play, PLAY covers sizes 2 to 14 with backpack straps and a neck warmer.
Should I size up in a Deux par Deux snowsuit?
Deux par Deux does not recommend buying a size larger than its size guide suggests. All three lines have Grow with Me sleeves that extend 4 cm (1.5 in) and adjustable pant hems to add wear as your child grows.
Which Deux par Deux line has the widest size range?
PLAY covers the widest range for most families: Deux par Deux lists it from size 2 to 14. DISCOVER runs from 2 to 8 and TEKNIK from 4 to 16, so TEKNIK is the only one of the three lines in size 16.
How cold is too cold for outdoor play, even in a -30°C snowsuit?
The AAP says outdoor play in temperatures or wind chills below -15°F (about -26°C) should generally be avoided. The Canadian Paediatric Society suggests keeping children indoors at -27°C (-16°F) or lower, temperature or wind chill. A snowsuit rating does not cover exposed skin.
