The Rho Heavyweight - Arc'teryx's warmest base layer pant - is made for cold days and mixed output. On the move, the Polartec® Power Stretch® Pro stretches for outstanding freedom of movement. During rest phases - or when it gets really cold - the men's Rho Heavyweight Bottom's soft brushed interior traps heat to keep you warm. The fleece's durable nylon outer has a smooth face for comfort under layers, and a zippered thigh pocket secures small essentials.
