If you’ve ever stood in a ski shop staring at a rack of jackets and pants, trying to figure out why some ski wear feels too baggy to move and others feel so tight you can barely zip them, you’re not alone. When I first started my journey as a ski wear supplier, I spent months answering that exact question from customers, from weekend skiers lacing up boots for the first time this winter to seasoned backcountry guides who’d been carving powder for decades. The truth is, picking the right ski size isn’t just about fitting into a number or a label—it’s about balancing three things: movement, insulation, and protection against the elements. And as someone who’s tested every inch of the ski wear we supply, I’m here to break that down in a way that’s practical, not just technical. Ski Wear
Let’s start with the biggest mistake I see people make: buying ski wear that’s way too big. I get it—you think extra room means you’ll stay warmer, right? Actually, no. Air trapped between layers keeps you insulated, but if there’s too much empty space between your base layer and your ski jacket, that cold air will circulate and make you colder, especially when you’re moving. Last season, a client came to me after buying a large jacket for his medium frame; he told me he was shivering halfway down a run, even with two layers under it. When he swapped it for a medium, he texted me the next day saying he’d been warm for his whole three-hour ski session. That’s because a properly sized jacket doesn’t swallow your layers—it holds them close so the insulation does its job.
But what about movement? Skiing isn’t sitting still. You’re bending at the knees, reaching up to adjust goggles, falling, and getting back up. If your jacket is too tight across the shoulders or the arms, you’ll be stuck pulling it up every time you reach, or it’ll restrict your turn. When we design our ski jackets, we build in 10 to 15 percent of extra room in the torso and arms, but only if it’s intentional. That extra space isn’t for fluff—it’s for your mid layer, like a fleece or a thin puffer, when the weather is milder. A common test we use with our own team is to zip the jacket fully, then raise your arms all the way over your head. If the hem pulls up more than an inch, it’s too small; if you can slide an extra hand between your back and the jacket, it’s too big. That sweet spot is where you want to be.
Pants are a whole different story, too. I’ve watched a lot of skiers buy pants that are too long, thinking they’ll grow into them or that the extra cuff will cover their boots. But when you’re skiing, your knees bend, and loose fabric at the ankle can catch on your ski bindings. That’s not just annoying—it can be dangerous. We measure our ski pants to hit right at the top of your ski boot’s liner, with about two inches of cuff space to tuck in your base layer or a thin pair of socks. For waist size, here’s another tip: don’t go by your street pants size. Ski pants are meant to fit over your hips and layers, so if you wear a 32 in jeans, you’ll probably want a 34 in ski pants to be comfortable with a base layer on. And if you like adjusting the fit on the mountain, look for pants with belt loops or suspender buttons—we add both to our lines for exactly that reason, so you can tighten or loosen them as you warm up or cool down.
Now, let’s talk about insulation, because size ties directly into that. Different ski wear is made for different temperatures, so your size needs to match what you’ll be doing. If you’re skiing in mild winter weather—say, 30 to 40 degrees Fahrenheit—you don’t need a thick, insulated jacket. A shell jacket (that’s the waterproof, windproof outer layer) with a medium mid layer under it will work best. For that, you want a size that fits close enough to feel the shell’s waterproofing against your mid layer, but still has room to move. On the flip side, if you’re backcountry skiing in subzero temperatures, you’ll want a more insulated jacket, with a little more room to fit a bulky puffer under it. Here’s where I’d caution against going too big: if there’s too much space between the jacket and your mid layer, the cold air will seep in, even if the insulation is thick. Our team tests each jacket in temperatures as low as -10 degrees, and we’ve found that the best fit for insulated jackets is one where you can pinch about an inch of fabric at the back of the jacket—any more than that, and you’re wasting insulation.
Body type also matters, and I hate that most ski wear brands only make one standard fit. I’ve had plenty of customers who are short in the torso but have long arms, or broad in the shoulders but slim in the waist, and off-the-rack sizes never work right. That’s why when we were developing our current line, we added two fits: a regular fit for most people, and a slim fit for those who prefer a more streamlined look and less bulk. If you’re on the shorter side, look for jackets with shorter body lengths—most brands list that measurement on the size chart, right next to chest and waist. Don’t just go by the chest size; measure your back from the base of your neck to your waist, and match that to the jacket’s body length. For tall skiers, we added extra-length torsos, too, so you don’t have to pull your jacket up halfway through the day to cover your lower back.
Wait, let’s get to the size chart, because that’s the most reliable tool you have. I know it’s tempting to go by what you wear in a T-shirt, but ski wear is designed for functionality, not casual wear. The best size chart will have measurements for chest, waist, hips, torso length, and arm length, not just a small/medium/large. Here’s how to measure yourself correctly: for chest, wrap a tape measure around the fullest part of your chest, under your arms, and keep it level. For waist, measure the narrowest part of your waist, right where your base layer would sit. For arm length, start at the center back of your neck, go over your shoulder, and down to your wrist bone—this is key for jacket sleeves that don’t ride up when you’re holding ski poles. Last year, a customer measured himself wrong, ordered a large jacket, and it was way too long in the arms. When he sent me his arm length measurement, we saw he’d only measured from his shoulder to his wrist, not from his neck, and that’s why the sleeve was too long. That’s a simple fix, and if you take those measurements correctly, you’ll get the right size 90 percent of the time.
Now, what about when you’re buying for kids? That’s another area I get a lot of questions about. Parents often want to buy a size up so their kids can wear the ski wear for two or three years, but here’s the thing: kids grow fast, but ski wear that’s too big can be unsafe. If a jacket is too long, it can get caught in a ski binding, and loose sleeves can pull goggles off mid-run. Instead, buy the size that fits right now, and if your kid is growing fast, look for ski wear with adjustable cuffs and hems—we add elastic cuffs that can be let out an inch, and hems that extend, so they can wear the gear for an extra season without it being too big. That’s a much better investment than a size-up jacket that doesn’t fit correctly.
Let me also talk about what to avoid. If a jacket’s shoulder seams are sitting past the end of your shoulder bone, it’s way too big. If the waist of the pants is sitting below your hip bones, that’s too loose, and you’ll have to hike it up all day. When we test our own gear, we have every new member of the team wear it on a long ski day, and if they complain about any of those things, we adjust the size specs. For example, a few years back, we thought our medium jacket would fit a 38-inch chest, but when our team tested it, someone with a 38-inch chest said the shoulder seams were too wide, so we adjusted the pattern to narrow the shoulders by half an inch. That’s the kind of small, practical change that makes a big difference on the mountain.
At the end of the day, choosing the right ski size is about matching your activity. If you’re a casual skier who hits the slopes once a month, you can go with a little more room for comfort. If you’re a dedicated skier who logs 50+ days a year, you’ll want a fit that lets you move without restriction, no matter the temperature. And as someone who’s spent years supplying ski wear to skiers of all levels, I can tell you that a correctly sized piece will make every ski day better—you won’t be adjusting your jacket every five minutes, you’ll stay warm, and you’ll have more fun carving turns instead of worrying about your gear.
