The Accelerator is a lightweight, packable down jacket built for alpine climbing, ski touring and summer mountaineering. It pairs a 20D Pertex Quantum ripstop shell with about 4 oz of 850 fill-power water-resistant down, plus synthetic insulation under the arms and behind the mouth guard where sweat builds up. The athletic cut is sized to layer over a base layer and a thin mid layer, which cuts dead space and drafts. Against heavier down jackets it trades bulk and a boxier fit for low weight and a small packed size; owners rate it highly for warmth-to-weight and packability.

Owners rate it very highly, praising its warmth for the weight, the small packed size and the trim fit that layers cleanly. Complaints center on the slim cut and the delicate shell fabric.
The Accelerator Down Jacket is a lightweight, packable hooded jacket for the backcountry. It suits mountaineering expeditions, ski tours and summer high-alpine backpacking trips.
The shell is 20D Pertex Quantum ripstop nylon, which keeps the wind out. It holds about 4 oz of ethically sourced, water-resistant 850 fill-power down. A PFAS-free water-resistant coating is applied to both the fabric and the down to protect against internal and external moisture. Synthetic insulation in the underarms and mouth guard keeps you warm during high-heart-rate activities.
The athletic fit is cut to sit over a base layer, and possibly a very thin mid layer. This reduces dead space to heat and cuts down on updrafts. Drawcords at the hood and hem keep out wind and hold in warmth. The jacket has zippered hand pockets and an internal zippered chest pocket. An integrated stuff sack in the left-hand pocket compresses the jacket to about the size of a standard 32 oz Nalgene.
