Arc'teryx Delta Fleece Jacket sets a new standard for technical fleece garments with its innovative construction and high warmth-to-weight performance. The fabric is soft and breathable, elevated to a new level by a unique hollow octagonal fibre core that delivers significantly better insulation without adding weight. The smooth outer surface makes the jacket easy to wear as a mid-layer while also increasing durability under friction against shell garments.

The fit is close-fitting and articulated for natural movement in the mountains. The new Delta models offer a little more room in the upper body and sleeves for increased comfort during high-intensity activities. Flat seams reduce chafing, and elasticated cuffs keep the garment in place. The jacket features a full-length front zip and a back length of 70 cm in size M, with variation between sizes.

A laminated chest pocket and two hand pockets provide practical storage, while a chin guard increases comfort when the zip is fully closed. The materials meet bluesign® requirements, contain recycled fibre, and are PFAS-free for a more sustainable footprint.

Delta Fleece Jacket is a thoroughly considered technical mid-layer suited to everything from fast mountain trips to long days of varying intensity – warm, lightweight, robust, and easy to use year-round.
