Bight Gear Men's Alpha Ascender Hoody

$279.00  $83.70
- +

 Insulation that adapts at every elevation. Breathes on the move and keeps the chill out in between. The Alpha Ascender Hoody combines Polartec® Alpha® and Polartec® Power Stretch® Pro™ for the ultimate in breathable insulation that regulates core body temperature and wicks moisture as you push above the treeline. Worn as a primary insulator on milder days or as a mid-layer on those extra chilly alpine starts, the Alpha Ascender Hoody works as hard as you do so you can avoid the layer shuffle and get after it.

General care for all garments: Machine wash cold with mild detergent, tumble dry medium, do not bleach, do not dry clean, 

and do not use fabric softener.

Additional care for waterproof garments: Machine wash cold with detergent formulated for technical clothing. Tumble dry medium, do not bleach, do not dry clean, and do not use fabric softener. As needed, tumble dry medium to refresh DWR or treat with spray application such as ReviveX. Ensure down insulation is completely dry before removing from the dryer. If needed, tumble dry down garments with clean tennis balls to restore loft. 


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. 


Athletic Fit: A slimmer fit designed for functional movement, and can be layered over base layers and light midlayers.

Relaxed Fit: The roomiest of our fit styles that allows for layering of multiple/heavier technical layers underneath.

Amazing for cold weather high output activity

This is an amazing piece for cold weather, high output pursuits. Just the right amount of insulation with a thin ls baselayer underneath. It manages moisture extremely well. When temps drop further, or wind picks up, throw an outer shell layer or vest over the top.
The construction with the back panel and under arms being Power Stretch, it moves extremely well and helps keep back sweat away. Also helps if layering thicker underneath, as it limits constriction by stretching where needed.
The Alpha insulation is amazing - can be soaked with sweat and in minutes will dry out. The pockets are perfect - the chest pocket will fit a large phone or electronic device. The inside pockets are big enough to cram skins or a water bottle if needed.

It's a win-win!

I have 2 of these awesome hoodies and when my son's birthday came around, I got him one! He has used his on 2 snowboarding days and absolutely loves it. I heard from a couple of his friends that he won't stop talking about it. Best piece of gear...ever!

Ascender / Solstice

I’ve enjoyed 2 summits of Rainier using your previous Mtn Logic Ascender - it worked well, but sizing was def on the small side. The Bight version sizing and length are perfect! Amazingly thin, yet warm - I love how this layers above your Solstice Hoody - the combination wicks out sweat and refuses to get cold. Been spending days skiing in this combo under a thin shell (I run warm, sister Katy adds your Fissure Tech Fleece) - no issues so far on chair rides. Planning 2 summits of Baker (one skiing) along with St Helens and Sahale this summer, Bight Gear an essential part! Thanks for amazingly thought out stuff - whats next

Returned for exchange but no replacement was sent

I recently purchased the Alpha Ascender Hoody and loved the jacket, but the size I ordered was too big. I returned the jacket per the return instructions and included my request to have a replacement sent back with a different size over a month ago. I have not heard anything back regarding the status of the replacement.
