When the water in your drinking bottle starts to freeze, you know it’s time to break out our softshell Ksyrium Pro Thermo Jacket. We used body mapping to position layers of PrimaLoft insulation where you need it most, making it the warmest jacket in our entire range. It’s a Regular Fit, with a little bit more room to accommodate your extra layers, but the stretch insert panels and ergonomic seams mean there’s no bagginess or flapping. The windbreaker membrane all over the jacket gives good wind-protection, and there are some neat season-specific touches like slightly wider pockets for gloved hands, an inner storm flap with a staydown zip and a quick cord for easy waist adjustment.

Clima Vent on the side allows air permeability and moisture evacuation to keep you cool and dry

The lightweight, multi-diameter Primaloft® Sport insulation provides superior warmth, water resistance, durability and fast drying loft Ergonomic shaped collar with fleece lining provides superior protection for your neck
