Kestrel UL 30 Sleeping Bag

With its roomy cut through the shoulders, the Kestrel is the choice if you’re looking for a mummy shape to accommodate a stout build when the temperatures stay around freezing. While not as thermally efficient for smaller types, a wider bag can also be comforting for those who like more space or practice yoga in their sleep.

The best warmest sleepin bag that kept me warm on cold breezy nights and days.Review by Christo
Very soft but you have to be careful with the fabric not to get tears on trees cause your wanna wake up and walk around thinking its to comfortable to be real. Reasonable price considering it should last forever since Feather Friends has anyway and has a great customer service base! (Posted on 11/23/2017)
Best Bag I've Ever HadReview by SAR Hiatt
It's not the smallest or lightest bag I could find, but the point of a bag is to keep you warm, and this is an amazing performer for the price. The shell fabric seems way too thin to be durable, but I have yet to nick in two years of regular use. It packs down well, and lofts back up quickly. The wrap-around horizontal down tubes allow you to shake down around to the bottom for warmer summer months; in winter I just add a bag liner for temps down to 15 degrees. Zipper never binds if you keep the draft tube out of the way. It cinches up tightly around your face on a cold night. REALLY well thought out and constructed. 30 oz. in a 9L compression sack. Awesome bags!!! (Posted on 8/4/2017)
Absolute qualityReview by Travis N
I purchased this for an Appalachian Trail thru-hike and it never disappointed. I can't say enough good things about this bag.

I loved purchasing something made in the USA. I loved the quality and craftsmanship. I trusted, and still trust this bag completely. I have been at or below the rating on it multiple times and it has never failed. I'm a big guy at 6'4" and the cut of the long feels like it was measured to me exactly.

There is absolutely no way to summarize how durable, compressible, warm, and trustworthy this bag is. I cannot wait to expand into warmer bags for winter trips up north. (Posted on 9/10/2014)
