Patagonia R1 Air Crew Top - Men's Black, M

What Our Gearhead(R) Experts Are Saying:"This crew is always in my pack-it vents like a champ when I'm moving fast and still insulates when temps dip. Great under a shell or on its own."We reach for the Men's R1 Air Crew Top when we need warmth that won't weigh us down.

From hut trips to chilly hikes, the R1 Air Crew Top is built to move with us. Hollow-core yarns trap warmth without bulk, and the slim yet flexible cut fits easily under layers or wears comfortably on its own.
