Style Features:

 Ultra-light Alpha Direct fabric, excellent weight-to-volume and insulation ratio.

Warm air is trapped in the middle layer when stationary, while efficient heat/moisture transfer provides dynamic warmth during movement.

Back/shoulder breathability and quick-drying properties reduce sweat sticking to the skin and minimise wear from backpacks, avoiding issues like 'burning back'.

Weight: 84g for size L (3).

Suitable for Fast Packing, hiking, trail running, and other activities.
