Bight Gear Men's Alpha Ascender Vest
Our Take
The guys over at Bight Gear liked their Alpha Ascender hoody so much, they decided to hack the sleeves off and turn it into one of those technical vests everybody’s wearing these days. But this is way more than technical “looking.” This vest is the product of 100,000+ vertical feet of testing by the world’s greatest mountain guides. Made with military-spec Polartec Alpha active insulation, and strategically located stretch panels, the Ascender has alpine credibility that the other guys only dream about.

Our products have been designed for climbers and outdoor users to be worn as a system of layering, and each piece has been fit for optimal performance. In general, our products have a slim, athletic cut and a little extra length. Our layers intentionally fit over each other. If you are between sizes, or prefer more room in your garment, we recommend you choose the larger size.
