A premium mid-layer fleece with high loft and warmth-to-weight ratio features zip chest pocket.

Heading out after waiting days for the perfect conditions to attempt the Crooked Couloir the Arcteryx Delta SV Jacket for men maximizes heat retention and breathability while stealthily skinning the west shoulder by headlamp. Drying quickly after a long pull the thermal mid-layer insulation that is constructed of high loft Polartec® Thermal Pro® fleece gives exceptional warmth for the weight which doesn't slow down your pace. As you test the summit cornice gusseted underarms minimizes body lift on a long reach and the full front zip with chin guard closes the heat gap at the stand up collar. Judging it a go a quick tug on the drawcord hem and retrieval of a couple of power gels from the laminated zip pockets sets the stage. The Delta SV Jacket is ready to drop in.
