The Dakine Deville Reversible Down Vest is a lightweight layer for skiing, snowboarding, and pretty much any outdoor activity in the cold. The body is insulated with 650-fill down for the most warmth with the least weight, and the shoulders and collar are insulated with synthetic PrimaLoft Eco for better performance if they get a little wet. This is an easy midlayer to stash in a pack just in case things get chilly, or wear for a bit of extra core warmth any day of the season.
