A long-sleeve running layer in Polartec® Alpha® Direct, designed to hold warm air while keeping its structure exceptionally open and light.
The 100% polyester fleece is hydrophobic, fast-drying and moisture-wicking, with loft that continues to insulate when damp. Unlike a dense midlayer, it lets excess heat pass as the pace changes.
Flat anti-chafe seams keep it comfortable beneath a vest or shell. Worn alone, the exposed insulation gives the long tee a distinct, almost raw texture.
