These Alpha 60 Joggers are jogger-style fleece pants made from Polartec® Alpha Direct at 60 gsm — the lightest weight in the Alpha lineup. Breathable and quick-drying, they trap warmth without added bulk, making them a favorite with backcountry skiers and backpackers as an underlayer or a packable, lightweight sleep pant. They feature a 1-inch elastic waistband and loose fold-over elastic cuffs for an easy, no-fuss fit.
