The Accelerator Down Jacket is perfect for an array of activities in the mountains - think demanding mountaineering expeditions, summer backpacking trips, and ski days with friends. The premium materials & athletic design create a lightweight down jacket that is made to perform.

The Pertex® Quantum ripstop nylon shell keeps the wind out and holds ~4oz of ethically sourced 850 Fill-Power, water resistant down for lightweight warmth. A PFAS-Free water-repellent coating on the shell fabric, combined with water-expanding thread, acts as the first defense against precipitation, while the PFAS-Free water-resistant down prevents internal moisture buildup.

Synthetic insulation mapping in high-moisture areas (underarms and mouth guard) keeps you warm during high-heart-rate activities.

The athletic fit is designed to fit perfectly over a base layer (and potentially a whisper-thin mid layer). This takes advantage of down’s insulating properties by reducing the need to heat unnecessary dead space and by reducing updrafts.

Hem and hood drawcords prevent unwanted airflow and work to keep you warm.

An integrated stuff sack in the left-hand pocket allows the entire jacket to easily compress to a size similar to a standard 32 oz Nalgene.

We use top-of-the line YKK zippers for all of our products.

It’s athletic fit is designed to fit perfectly over a base layer (and potentially a whisper thin midlayer). This takes advantage of down’s insulating properties by reducing dead space between your body and the down. If you are looking to layer more than this underneath, we recommend sizing up.
