Outerwear at REI. When the weather starts to cool, it’s time to bundle up and extend the season of outdoor fun. Puffy jackets and winter vests offer just the right amount of cozy. But when the flakes fly, snow clothing and winter hats will keep you warm when skiing, snowshoeing or playing in the snow. Add women’s winter boots or men’s winter boots for toasty toes, and you’ll be set for the season.
