When versatility, warmth-to-weight ratio and stretch are priorities, the Arc’teryx Men’s Delta Jacket is the ideal mid layer, designed to perform across a range of alpine activities. The Polartec Power Dry fleece has a high level of stretch for outstanding freedom of movement, the grid interior construction delivers great warmth with little weight and the smooth outer surface makes layering easy. The Delta jacket also features thumb loops to help keep the sleeves down, two zipped hand pockets with corded pulls and a laminated chest pocket with a laminated zip. The slim fit is patterned to stay close to the body; its low profile eliminates bulk, moves with you, and comfortably fits under outer layers.
