Arc'teryx - M's Delta Jacket

Durable fleece jacket delivering thermal performance for minimal weight.

A new type of fleece, a new level of performance. Still soft, still breathable, it’s elevated with an innovative octagonal hollow-core construction for a much better warmth-to-weight ratio and a smooth face for easy layering and improved durability. A trim fit patterned to move and low-profile seams that reduce chafing combine to create a technical, comfortable fleece for all your mountain missions.
