For skiing and cold days, the best men's underwear is a snug, synthetic layer that pulls sweat off your skin and dries fast, such as polyester or polyamide boxer briefs with a longer leg. Save cotton for the evening: it is lovely by the fire, but on the slope it holds moisture and leaves you feeling chilly once you stop moving.
Why underwear matters more in the cold
Most people think about jackets and gloves first, but the layer touching your skin decides how comfortable the whole day feels. On a ski run you warm up, sweat a little, then sit still on a chairlift in the wind. Whatever is sitting against your skin at that moment either stays damp or dries out.
- Damp fabric feels cold. A layer that wicks and dries quickly keeps that clammy feeling away between runs.
- Bulk causes pressure points. Under ski pants, thermal leggings and boots, loose fabric bunches up. Close-fitting cuts lie flat.
- Long days need staying power. Leg hems that roll up or waistbands that fold over get annoying after hour three.
The layering system, from skin outwards
Cold-weather dressing works in layers, and underwear is layer zero. Think of it like this:
- Underwear: close-fitting, quick-drying boxer briefs or long compression shorts.
- Base layer: a fitted top (a compression shirt or long-sleeve thermal) and thermal leggings if it is properly cold.
- Mid layer: fleece or a light insulated jacket you can take off when the sun comes out.
- Outer layer: waterproof, windproof ski jacket and pants.
Each layer should be a little looser than the one beneath it, so moisture can travel outwards. That is why the innermost layer should be the snuggest of all.
Which fabrics work best on the slopes
Here is how the fabrics in our range compare for a day outside in winter:
| Fabric | How it handles sweat | Best moment to wear it |
|---|---|---|
| Polyester + spandex | Moves moisture away and dries fast | Skiing, snowboarding, winter hikes |
| Polyamide (ice silk) + spandex | Smooth, slick and quick-drying | Active days, travel to the resort |
| Nylon + polyester (top) | Stretchy, breathable, quick-drying | Base layer under a ski jacket |
| Cotton + spandex | Soft, but slower to dry when wet | Après-ski, evenings, the drive home |

Cut and leg length: go longer when it is cold
For winter sports, a longer leg is your friend. Our Long Compression Shorts have a 9 inch leg, flatlock seams and a 3D U-shaped pouch, made from 90% polyester and 10% spandex with mesh at the groin. The longer leg sits under thermal leggings without creasing and keeps the inner thighs covered when you are in a ski stance all day. They come in black, navy blue, blue, sky blue, green and brown, sizes S to 2XL.
If you prefer a classic length, the Moisture-Wicking Compression Boxer Briefs (90.8% polyester, 9.2% spandex) have a contoured pouch, a wide elastic waistband and a tagless build. They are designed to stay put without rolling at the legs, which is exactly what you want under ski pants.
Don't forget the top half
A fitted top under your mid layer does the same job for your torso. The Arjen Kroos Compression Shirt is a seamless tank made from 88% nylon and 12% polyester, silky, stretchy and quick-drying, in black or white. Wear it directly against the skin, then add a long-sleeve layer and fleece on top. Because it is sleeveless, it also works well indoors at the resort when you strip down to one layer. Our compression shirt guide covers sizing in more detail.
Tip: if you sit between sizes on a base layer, pick the size that feels snug but lets you breathe deeply and lift your arms freely. Too tight and it restricts movement, too loose and it stops working as a close layer.
What to pack for a ski trip
A week in the mountains does not need a huge bag of underwear. A practical plan:
- 3 to 4 pairs of performance boxer briefs for skiing, rinsed in the sink and hung overnight, since quick-dry fabrics are usually ready by morning.
- 1 to 2 compression or base-layer tops for under your jacket.
- 2 to 3 pairs of soft cotton boxer briefs for evenings, travel days and lounging. The Cotton Boxer Briefs with 3D Pouch (95% cotton, 5% spandex) have a no-dig waistband that is comfortable after a long day in ski pants.
- A spare pair in your day pack in case you end up soaked after a fall in deep snow.
Frequently asked questions
Should I wear cotton underwear for skiing?
It is better kept for après-ski. Cotton is soft but dries slowly, so once you sweat it stays damp and can feel cold on the chairlift. A polyester or polyamide blend is the better choice on the slope.
Are compression shorts good under ski pants?
Yes. Long compression shorts lie flat under thermal leggings and ski pants, and the longer leg helps stop fabric from riding up while you move.
Do I need thermal leggings as well as underwear?
On very cold days, yes: wear your underwear, then thermal leggings, then ski pants. On mild spring days, performance boxer briefs under ski pants are often enough.
How tight should winter underwear be?
Snug and smooth against the skin without pinching. If the waistband leaves deep marks or you cannot squat comfortably, go one size up.
