Warm stretch-fleece base layer made for cold days and mixed output.
Synthetic fleece textiles with stretch, warmth and air permeable properties. Offers durability.
Versatile high performance designs for diverse activities and conditions.
The Kyanites – our warmest base layer tops – are the choice for cold days and stop-and-start activities. On the move, the Polartec Power Stretch Pro fleece stretches for unrestricted freedom. During rest phases, or when it’s really cold out, the soft brushed interior traps heat to keep you warm. The fleece’s durable nylon outer has a smooth face for comfort under layers, and thumbholes hold the sleeves in place.
The Kyanite Base Layers were previously known as the Rho Heavyweight base layers.

NOTE: Arc'teryx sizes are intended to fit the above body measurements. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.
Fit: Fitted
Our trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over first layers or under outer layers.
