The Ski Jacket Fit Guide: Getting the Size Right

Most ski jackets that get returned are not returned because the fabric is wrong, or the features are wrong, or the colour disappointed. They are returned because they don’t fit.

Getting the fit right is harder than it sounds, because a ski jacket doesn’t fit the way a normal jacket does. It needs more room in some places, less in others, and the trousers-and-top-standing-still test is almost useless. Here is what actually matters.

The five things to check

A ski jacket should be right in five areas. Get these right and you have a jacket that will work on the mountain.

1. Shoulders

The shoulder seam should sit at the edge of your shoulder, not halfway down your upper arm. A jacket that is too big drops the seam off your shoulder and the whole jacket sags as a result. Once you notice this, you can’t unsee it on other people either.

If the shoulders are wrong, the jacket is the wrong size. No other adjustment fixes this.

2. Sleeve length

Ski jacket sleeves need to be longer than a normal jacket’s sleeves. When you put your arms out in front of you, as if you are holding ski poles, the sleeves should still cover your wrists. When you raise your arms above your head, the sleeves should not ride up to your mid-forearm.

The inner cuff, the stretchy sleeve that sits over your base layer, matters too. It should cover your wrist with your arm extended, so snow can’t work its way up.

Most people buying their first ski jacket underestimate how much sleeve length they need. If in doubt, longer is better than shorter. You can push sleeves up. You cannot extend them.

3. Torso length

A ski jacket should cover your backside when you bend forward in a skiing stance. Stand normally, then lean forward at the hips as if you are about to start down a run. If your lower back is exposed, the jacket is too short.

This matters for two reasons. One: snow gets in through gaps. Two: your base layer and mid-layer will ride up when you move, and a short shell means they are exposed to the elements.

Long enough to cover the hips in a skiing stance. Not so long that it bunches when you sit on a chairlift.

4. Room to layer

This is where most people get fit wrong. A ski jacket needs to fit over a base layer and at least one mid-layer, not over a T-shirt.

Try the jacket on with what you actually plan to wear underneath. If you don’t have a mid-layer yet, wear a fleece or a thin puffy jacket. The ski jacket should close comfortably over all of that, with enough room to lift your arms without the chest pulling tight.

If it fits over a T-shirt but struggles over a fleece, it is too small. If it has huge amounts of slack over a fleece, it is too big.

5. Zipper range

Close the zip all the way up, then try to bring your chin down to the top of the collar. Can you? Is the collar high enough to cover your lower face on a windy chairlift, without pressing uncomfortably into your neck?

A good ski jacket zips up high enough to reach your chin comfortably. Many midrange and premium jackets have a microfleece chinguard at the top of the zip to stop it rubbing.

Fit types you will see

Different brands use different fit philosophies. The main categories:

Regular fit: traditional, close-ish cut. A good default for most people.
Relaxed fit: more room in the chest and shoulders. Suits taller, broader or layer-heavy skiers.
Boxy fit: deliberately squared-off, popular in freestyle and park styles. Short in the body, wide in the chest.
Slim fit: closer-cut, often women’s specific, good for smaller frames but not good for heavy layering.

Dope Snow, for example, publishes clear fit categories for each of its jackets, the Adept is regular fit, the Blizzard Pullover is relaxed, the Spartan is boxy. Most reputable brands (Montec, Helly Hansen, Rossignol, Salomon, Burton) do something similar. Check the fit description before you buy, and check it against what kind of silhouette you actually want.

Men’s vs women’s cuts

Women’s ski jackets are not just smaller men’s jackets. They are cut differently, narrower in the shoulder, different chest shaping, more shaped through the waist. Men with narrower frames sometimes find women’s jackets fit them better, and vice versa. There is no rule that says you have to buy the cut labelled with your gender.

If you are borderline on sizing or shape, looking across the line can help.

Where size charts go wrong

Every brand publishes a size chart based on chest, waist and height. Use these as a starting point, not a final answer. What the charts don’t tell you:

How much room is built in for layering, varies massively by brand
How long in the torso the jacket runs, some brands run long, some short
How the shoulders are cut, some brands are broad, some narrow

The only way to be sure is to try it on. Online return policies are your friend. Buy the size the chart suggests, plus the size above, try both with a mid-layer, return the one that doesn’t fit.

Common mistakes

Three patterns I see most often:

Buying down a size to look “fitted”. You end up with a jacket that pinches at the shoulders and can’t close over a mid-layer. Skiing miserable. Refund requested.
Buying up a size to “be safe”. You end up with a jacket that sags off the shoulders, sleeves too long, hood swamping your face. Snow gets in at every gap.
Buying from a picture. A jacket looks one way on a model and another way on a real body. Try before you commit.

What to do if you can’t try before buying

If you have to buy online without a shop visit:

Read the full size chart, not just the S/M/L label
Read the brand’s fit description for the specific jacket
Look for reviews that mention the reviewer’s height, build and normal size
Order two sizes if budget allows, return the worse one
Try on with real mid-layers, not over a bare chest
Walk around in the jacket for 10 minutes before cutting tags off

A jacket that fits is worth more than a jacket that spec-sheets well

A £400 premium jacket that is half a size wrong will be outperformed by a £200 jacket that fits properly. Fit is the single biggest factor in whether you will enjoy wearing your ski jacket. Get it right, and the rest becomes detail.
