Rossignol Clothing 4WS Blackside Insulated Womens Jacket 2027

The Jacket

Rossignol built the 4WS Blackside for skiers who want to move in their outerwear instead of fighting it. It's a two-layer insulated jacket with stretch woven right into the face fabric, so reaching up for a chairlift bar or dropping into a tuck doesn't yank the hem up or lock your shoulders. The cut follows a woman's frame instead of a boxy unisex block.

What We Like

Most insulated shells fight you a little through the shoulders and back - this one doesn't, and you notice it the first time you plant a pole and reach across your body. The raglan sleeve cut adds to that, keeping the shoulder seam out of the way of your pack straps or a chairlift bar.

Tech That Matters

The recycled 4-way-stretch face fabric carries a 20K waterproof and breathability rating - extremely waterproof, extremely breathable, in plain terms - with windproof performance under 2 CFM. That's a serious number for a piste jacket and it means wet, heavy snow isn't soaking through on a wet day. PrimaLoft insulation handles the warmth side, and it keeps working even if the fabric gets damp, which down can't claim. Pit zips let you dump heat on a bluebird day without stripping a layer. The hem and cuffs both adjust to seal out snow, and the cuffs close with velcro so you can cinch them over or under a glove.

Fit & Sizing

This is a fitted, feminine cut - not baggy, not boxy - built to layer a midweight fleece or light puffy underneath without feeling stuffed. The stretch fabric gives you room to move without needing to size up for movement's sake. If you're between sizes and plan to layer heavy underneath on cold days, go up one. If you run warm or layer light, true to size works fine.
