These Alpha 90 Joggers are jogger-style fleece pants made from Polartec® Alpha Direct at 90 gsm — Sambob's best-selling, most versatile Alpha weight. Warm enough to wear on its own and still packable enough to disappear into a bag, they're a favorite with backcountry skiers and backpackers who want one warm layer that does double duty. They feature a 1-inch elastic waistband and loose fold-over elastic cuffs for an easy, no-fuss fit.
