Kids Ski Suit Buying Guide: One-Piece, Bib Pants, or a Set?
A kids ski suit can sit in the same band as the jacket that matches it, and still hand you more garment. At 110 to 130, the complete one-piece suit and the standalone ski jacket share a band. Same 18,000 mmH₂O waterproof rating, same 9,000 g/m²·24h breathability, same -25°C comfort rating. Same band, and the suit already includes the legs. If that reads backwards, it is because most parents read a suit as the sum of its parts: jacket, then pants, then compare. The NANEND kids range does not behave that way, and the gap is wide enough to change what you buy. This guide covers the 10 outerwear pieces in the kids line: two one-piece suits, three two-piece sets, four bib pants and one jacket. It explains what separates the three shapes, why the most waterproof piece is not the top-band one, and how the size numbers work. The decision list sits at the end. Key takeaways A full one-piece suit sits in the same band as the matching jacket at 110 to 130, and in the same band again at 140 to 150. The mid-band bib pant ties the highest waterproof rating in the kids line at 20,000 mmH₂O, and the top-band color-block set sits 2,000 mmH₂O below it. Buying from scratch, the animal-hood one-piece covers the whole body in one purchase, where a jacket plus the entry-band bib takes two. If a jacket is already in the closet, the entry-band bib is the smallest step, but it stops at 15,000 mmH₂O and starts at size 120. The size number is body height in centimetres. The line publishes no age conversion for it. A kids ski suit can share a band with its jacket Put the two products side by side and the band labels look like a mistake. The color-block kids ski jacket sits in the mid band in sizes 110 to 150, rated 18,000 mmH₂O, 9,000 g/m²·24h and -25°C. The animal-hood one-piece suit sits in the mid band in sizes 100 to 130, at the identical 18,000 mmH₂O, 9,000 g/m²·24h and -25°C, with the legs attached, underarm vents and a rear zip. Same band for a full suit as for the jacket on its own. It is not a lighter build, either. Both one-pieces are tested to 20,000+ abrasion cycles and the jacket to 20,000, so the garment at the same band is a step up in abrasion resistance. The obvious reply, that a suit at the same band must be built lighter, does not survive the spec column. The same comparison holds a size band up. At 140 to 150, the color-block one-piece suit and the jacket are in the same band. The same band, not a lower one. Two garments for one band, with the same membrane numbers. What the jacket gives back at that band is detail: a fixed hood, a built-in snow skirt, a double-layer cuff guard, a nylon waterproof zip and a 3D cut. The one-piece has hook-and-loop cuff tabs over elastic inner cuffs, a rear drop-seat opening, multiple zip pockets and elastic ankle cuffs. Neither list is strictly better. The band label does not tell you which one you are getting. Band and specification run on separate tracks here, and the smaller, lower-band garment is often the more protected one. See the kids ski sets side by side Three kids ski suit shapes, and what each one is Every kids ski suit in the line is one of three architectures, and the word on the label does not always match the garment. Solid means included, dashed means not. The label on a listing does not always match what ships. Shape Products Band Sizes What is in the box One-piece suit (snowsuit) 2 entry to mid 100 to 130, 110 to 150 One shell for torso and legs, hood attached, rear opening for bathroom stops Two-piece set 3 top 110 to 150 Jacket plus bib pants, sold as one unit Bib pants, sold alone 4 entry to mid 120 to 150, 110 to 150 Pants only, worn with a jacket you already own Jacket, sold alone 1 mid 110 to 150 Jacket only, needs pants The one-piece. A kids snowsuit in the strict sense: no waist seam, no gap at the lower back, nothing to lose in a cubby. Both are insulated for -25°C and both open at the rear for toilet stops, the objection parents raise first. One model adds a 3D animal-shaped hood in four characters; the other is color-blocked and uses a hook-and-loop cuff tab over an elastic inner cuff. Anyone shopping a kids one piece ski suit is choosing between those two, and nothing else in the line. The two-piece set. A kids ski suit set pairs a jacket with bib pants, designed and sold together. All three are rated to -25°C; two of them carry 20,000 mmH₂O, the third 18,000. Both 20,000 sets add underarm vents and adjustable suspenders on the pant half, and the one that runs 110 to 140 also has a built-in snow skirt. Bib pants alone. Four products, and the practical core of the line. Kids ski bib pants cover the lower back that a jacket hem leaves exposed, and they stay put when a child bends, falls and rolls. If your child already has a jacket that fits, this completes it. The four differ on hardware the specification table does not list, which is what the kids ski bib pants guide takes apart. Jacket alone. One product, mid band, and worth knowing about only as a pairing. On its own it does not make a suit. Two products share a single title, the animal-hood one-piece and the color-block one-piece, and two more titles point the wrong way: the Ice Warrior pants are named "Overalls" while the specification reads "Kids' 3-layer bib snow pants", and the top-band set has "overalls" in its web address while being a jacket and pants. Read titles and you get four one-pieces. The real number is two. The band ladder is not a spec ladder Sort the kids outerwear by band and the specification column refuses to cooperate. Ten products, sorted by band. The waterproof column does not follow the ladder.

Six products report cycles on an abrasion test; the top-band color-block set reports a multiple of the national standard. The two are not on the same scale and cannot be ranked without the test method. All ten are rated for -25°C. Every waterproof figure above is a hydrostatic head test: the water pressure a fabric holds before it leaks, so 20,000 is twice the resistance of 10,000. Three things fall out of the sort. The entry-band bib ties the highest waterproof rating in the line. The thickened abrasion-resistant bib pant is rated 20,000 mmH₂O with taped seams and Grade 5 surface repellency: it matches the two top-band sets that sit at 20,000 mmH₂O and beats the third, all from the mid band. The top-band suit is not the most waterproof one. The color-block kids ski suit set is rated 18,000 mmH₂O, which is 2,000 mmH₂O below both of the other top-band sets. What the step up buys is breathability at 9,000 instead of 8,740 and pants straps that stretch without pinching. A real trade, not a waterproof upgrade. Two bibs in the same band are not the same bib. Both mid-band options read 18,000 mmH₂O and 9,000 g/m²·24h. The difference is in the abuse numbers: the 3-layer version is tested to 30,000 abrasion cycles, the 2-layer color-block version to 20,000, and both reinforce the rear hem where a bib wears through first. For a child who spends the day on the snow rather than on the lift, that 10,000-cycle gap decides it. Browse the full kids ski wear range Buying from scratch vs adding to a jacket you own The answer to "what is the shortest route to a full suit" flips depending on what is already hanging in the closet. Both answers are correct. Neither is universal. Case one: nothing fits anymore. You need torso and legs, and you are starting from zero. Route What it involves Where it lands One-piece suit One garment, no waist seam, legs included Complete suit in one purchase Jacket plus entry-band bib Two garments, 18,000 mmH₂O at the jacket and 15,000 at the bib, two separate waist seals Complete suit in two purchases, the weaker half at the legs Jacket plus mid-band bib Two garments, 20,000 at the bib against 18,000 at the jacket, two separate waist seals Complete suit in two purchases, no weak half Two-piece set Two garments designed together, waterproofing and size range aligned at the factory Complete suit in one purchase, one size decision At 110 to 130, the animal-hood one-piece covers more of the body in one purchase than a jacket plus the entry-band bib, and sits one band below the top-band set. At 140 to 150 that suit no longer fits, so the comparison moves to the color-block one-piece, which comes in below a jacket plus bib and below the top-band set, while matching the jacket's own band. If you are outfitting a child from nothing, a one-piece is the shortest route to a complete, sealed suit, and it is not close. Case two: the jacket still fits. Now the question is only how to cover the legs, and the ranking reverses. Option Band Waterproof Smallest size Entry-band bib entry 15,000 mmH₂O 120 Highest-spec bib mid 20,000 mmH₂O 110 3-layer bib mid 18,000 mmH₂O 110 Stepping down to the insulated bib pant at the entry band gives up waterproofing from 20,000 mmH₂O to 15,000, surface repellency from Grade 5 to Grade 3, breathability from 8,740 to 8,000 g/m²·24h, and size 110 entirely. The suspenders adjust, the legs are cut loose for layering, and there are built-in snow gaiters at the hem, so it is a real bib, just the wetter of the two. Three conditions decide it: your child is 120 cm or taller, the jacket already seals at the waist, and the snow they ride is cold and dry rather than wet and coastal. Meet all three and the entry band is the right call. Miss any one and the mid-band pair is worth the step up. Kids ski suit sizing: the number is height, not age These are centimetre codes, and every kids product page says so: sizes refer to the child's height in centimetres. No listing converts a code to an age. Height sets the starting column and weight can move you up a code; the page's chart pairs each height with weight bands, and a 110 cm child in the 26 to 30 kg band is directed to 120. A child who measures 108 cm buys the 110, not a size picked by birthday. What the listings do publish is availability, and that is where the real constraint sits. Count the size options across the ten outerwear pieces and the shape of the range appears on its own. Size Products that offer it 100 1 of 10 110 8 of 10 120 10 of 10 130 10 of 10 140 9 of 10 150 8 of 10 The middle of the range is covered completely: at 120 and 130, every outerwear piece in the line fits. Both ends narrow, and the bottom narrows hardest. One product reaches 100. Eight reach 110. Nine reach 140, and eight reach 150. The smallest shoppers are the hardest to outfit. Two constraints are worth knowing before you fall in love with a colorway. Size 100 has exactly one option in the entire line. The animal-hood one-piece is the only outerwear piece that comes in 100. If your child measures 98 to 102 cm, that is the suit, and the choice is really about which of the four characters you want on the hood. No bib pant starts below 120. The entry-band pair begins at 120, so a 110 cm child who already owns a jacket cannot finish the kit with the entry-band bib. The two mid-band pairs both start at 110, which is the reason to step up at that size. Size codes do not map to a single age across brands, which is one more reason to buy from the two measurements the chart asks for. Stand the child against a wall, add a centimetre for socks, then check the weight band before you commit. What else the kit needs The suit is the largest item, not the only one. A cold, wet child is usually missing something above the neck rather than below it. Item Options Bands Goggles Three kids and youth models, including a flip-up lens entry Helmet Dial-fit ABS shell, in-mold construction, in-mold with rotational impact protection and a rescue reflector entry to top Hip and knee pads Overpant style, XS to M, hook-and-loop straps entry Ski socks Mid-calf, five colors entry The kids helmet line is where the steps climb fastest, and they are about construction rather than color. At the bottom of that range the shell is ABS over EPS foam, with a rotary dial that adjusts to head size and reflective markings on three sides. One step up, the shell is in-mold, bonded to the foam, with a removable liner and certification to ASTM, EN and GB standards. At the top of the range the same build adds a rotational impact protection system and a rescue reflector. Certification is published for the two in-mold helmets and not for the ABS one. Goggles are the item parents most often buy badly, by buying big. All three kids models use a soft frame shaped for a child's face and a strap that stays under a helmet, and the top of the three flips the lens up 90 degrees so fog clears without taking the goggles off. That flip matters more for a five year old than any lens tint. Pads are worn over the pants in sizes XS to M, and cover hips and knees with layered foam and hook-and-loop straps. See kids protective gear and kids ski goggles FAQ Can a child get a one-piece ski suit on and off alone? It takes longer than a bib, because there is no waist opening to step through. The two objections parents raise are bathroom stops and overheating, both handled: both have a rear opening so a child does not undress in the cold, and both have underarm zip vents. What it will not do is let a four year old manage a bathroom stop alone. Should you size up a kids ski suit for growth? Only when the child measures between two codes. The cuts are built loose enough for a base layer, and the suspenders and cuffs adjust, so the code matching measured height already leaves room. A suit two sizes up puts the ankle cuff past the boot, which is colder than one that fits. Which is warmer, a one-piece or a kids ski suit set? Both are rated to -25°C, so the rating does not separate them. The structural difference is the waist: a one-piece has no seam there, and a bib pant covers the lower back that a jacket hem can leave exposed. Those sets answer this with 20,000 mmH₂O waterproofing rather than with warmth. What if your child needs size 100 or 110? At 100 there is one: the animal-hood one-piece. At 110 there are eight products, from the mid band to the top band. A child at the 100 to 110 boundary takes the same one-piece in 110. Do kids ski bib pants replace a snow skirt? A snow skirt closes the gap at the waist but does not extend the jacket. When a child bends, sits on a lift or falls, the hem rides up and the lower back is exposed. A bib puts that coverage on the garment that does not move, so it earns its keep for a child who falls forty times a morning. What should you ask a ski school before buying for a child? Ask the program for its own list, since requirements differ. What comes up across programs is a waterproof outer layer with no gap at the waist, a helmet, and goggles that sit under that helmet. The short version Match the scenario, not the band label. Buying for a child with nothing that fits, 100 to 130 cm: the animal-hood one-piece. Lowest-band complete suit in the line, and the only option in size 100. Buying for a child with nothing that fits, 140 to 150 cm: the color-block one-piece. Same band as the jacket, twice the garment. Already own a jacket that fits, child is 120 cm or taller: the entry-band bib, if your snow is cold and dry. Already own a jacket, child is 110 cm, or you ski wet snow: the mid-band bib at 20,000 mmH₂O. It ties the highest waterproof rating in the line. You want the hardest-wearing pants: the mid-band 3-layer bib, tested to 30,000 abrasion cycles with a reinforced rear hem. You want one purchase, one decision, maximum waterproofing: a top-band two-piece set at 20,000 mmH₂O, in 110 to 140 or 120 to 150. You want the highest breathability in a set: the top-band color-block set at 9,000 g/m²·24h, against 8,740 on both of the other top-band sets. The rule behind all of it: read the specification column, then the band, then decide. The two do not run in parallel in this range, and a parent who assumes they do will pay more for less waterproofing every time. If you are kitting out yourself at the same time, the adult ski suit guide walks through the same decisions for grown-ups. The whole kids collection is here.
