Arc'teryx RHO Heavyweight Men's

Ideal for cold weather and activities of varying intensity, the Rho Heavyweight Top is our warmest base layer. Polartec® Power Stretch® Pro fabric provides exceptional freedom of movement during exercise. During rest periods, or in particularly cold weather, the soft, brushed interior retains warmth. The durable nylon fleece has a smooth exterior that slides easily under a jacket, the stand-up collar provides warmth, and the long front zip makes both dressing and ventilation easy.
