Rossignol Siz Mens Pant

The Pants

The Rossignol Siz is a solid insulated ski pant built for skiers who want real waterproofing and a clean, straight-leg fit without paying for features they'll never use. It's a 20,000mm waterproof / 15,000g breathable 2-layer shell with 60g of 100% recycled polyester insulation inside. That combination keeps you comfortable on cold bluebird mornings and genuinely dry on messy weather days.

The critically taped main seams close off the spots where water works its way in. Add a PFC-free DWR finish on the outer fabric, and you've got a pant that handles moderate snow and rain without leaning on chemistry that's going out of use everywhere anyway. Built-in gaiters seal around your boot — coated nylon with anti-slip elastic and a reinforced bottom edge that holds up against ski edges season after season.

The waist adjusts to dial in the fit as you layer up or down, and two zip hand-warmer pockets cover your storage needs on the hill. The classic straight-leg cut gives you enough room to move freely in a skiing stance. Rossignol cuts this one a touch on the slim side — if you're between sizes, go up. Our Rossignol clothing size chart is a good starting point before you order.

What we Like

The 20K waterproof rating is the number that earns our confidence here. A lot of pants at this price point sit at 10K or 15K — the Siz goes higher, so you're covered on a full day of heavy, wet snow without soaking through. The 60g insulation is light enough that you're not roasting on a warmer afternoon, but it adds enough warmth that a midlayer base is usually all you need underneath.

The reinforced cuffs are the small detail we always point out in the shop. Any pant takes abuse from ski edges at the boot line, and without reinforcement that cuff frays fast. Rossignol addressed it. For the price, that's a spec you'd normally expect on a pant at twice the cost.

One honest limitation: the 60g insulation works well in cool to cold conditions, but on a genuinely frigid day — single digits or hard wind — you'll want a thermal base layer underneath. These aren't the warmest pant in the building. They're the right amount of warm for most days, and they breathe well enough that you won't be soaked in sweat when it warms up.
