Arc'teryx Delta Jacket is a technical and versatile mid-layer that serves as a key component in a modern layering system. The jacket combines breathability, durability and soft comfort, and the innovative fleece construction with hollow-core fibres delivers impressive warmth relative to weight.

The materials are developed to transport moisture efficiently and maintain a stable temperature during both high activity and calmer moments. The Phasic AR II fabric contributes stretch, warmth and a comfortable feel against the skin, while flatlock seams reduce friction and make the jacket optimal as a base layer beneath a shell jacket. The smooth outer fabric allows the jacket to glide easily under outerwear, while the construction provides increased durability during extended use.

The Delta Jacket has a close-fitting, articulated design that follows movement without restriction. Elastic cuffs and an elastic hem keep the jacket in place and contribute to a secure and comfortable fit.

Storage options consist of two spacious hand pockets and a laminated chest pocket that lies flat without creating bulk under other layers. A chin guard at the top of the zip provides extra comfort when the jacket is pulled fully up against cold wind.

Arc'teryx Delta Jacket works excellently both as a warming mid-layer beneath a shell jacket in demanding conditions, and as a standalone garment in camp, on a cabin trip or on relaxed outings when the temperature drops.
