Rho Heavyweight Mock Neck W

Arc'teryx Rho Heavyweight Mock Neck W

The Rho Heavyweights – our warmest base layer tops – are 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 fleece’s soft brushed interior traps heat to keep you warm. The fleece’s durable nylon outer has a smooth face for comfort under layers, the mock neck extends warmth, and a kangaroo pocket stashes your smartphone and warms your hands.

The Rho Heavyweight Mock Neck was previously the Rho AR Mock Neck.

Size and Fit Tips: Regular Fit - Our classic fit is cut comfortably throughout the chest, waist, hip, and thigh. It allows freedom of movement, provides shape, and layers comfortably under our insulation and midlayers.
