1/4-Zip Octa Hoodie

Ultralight: Weighs roughly half as much as standard polyester fleece.
Warm: Traps body heat in the hollow fiber's eight radial channels.
Breathable: Vents excess heat continuously — an active layer, not a windbreaker.
Durable: Resists snags and tears better than comparable ultralight fleeces.
Quick-Drying: Sheds moisture fast thanks to the hollow-core fiber structure.

Teijin Octa®. A light, breathable active layer with a brushed fleece inside, flat mesh outside.

Popular with runners, fastpackers, and anyone moving hard in the cold. Best worn under a wind or rain shell — Octa breathes so well it offers almost no wind resistance on its own.

5oz for a Wide Medium

This is a delicate fabric and must be treated as such. It will snag easily, so keep it away from Velcro, dog claws, and bushwhacking. Machine wash cold and hang dry.
