Invaluable warmth at a valuable price.

The Big Agnes Boot Jacket Sleeping Bag provides wet weather protection and lofty down for backpackers on a budget. Down insulation ensures lofty warmth without the weight, as well as the compact convenience that backpackers need. Big Agnes treated the down with DownTek to retain its lofty warmth in moisture-riddled environments, and the shell has a water-resistant treatment to shed liquids for even more protection.

Big Agnes styled the Boot Jacket with a weight-saving mummy shape, and the contoured hood has a drawcord to ensure a snug fit as well. There are draft tubes around the collar and inside the full-length zipper to seal out winds. This sleeping bag also has internal loops for liners, and external loops for airing out. Big Agnes included a stuff sack for the pack and a storage sack for the garage.

Big Agnes Traditional Down Mummy Bags

Our traditional down mummy bags deliver high value and performance in a lightweight bag. Ideal for backpacking but versatile enough for couch surfing, they are insulated with DownTek™ and use baffle construction for efficient heat distribution. If you’re in the market for a mummy shaped bag constructed with high quality, lightweight materials, these bags are your ticket to traveling fast and light.

Packs Down!

  • Familiarity: I've used it several times

This bag is awesome. It packs super small and is very lightweight. Down is the way to go, and this thing is toasty. Zipper and all around construction seems great. Would recommend!!

Great bag for the price.

  • Familiarity: I've used it several times

I picked this bag up before the start of a month long trip though Utah, leaving the old synthetic bag I have used for years back home. I was looking to upgrade to a down bag but was on a tight budget and got this bag for 150 on sale. This is my first down bag, but it far exceeded my expectations. I used this bag in temps that dropped below the 20s at night, and while wearing some base layers, I was more than comfortable. Only cold spot I noticed were along the zipper if the baffle got moved, but that's an easy fix and it's back to the warmth. I used this in combination with an insulated Big Agnes air core that is years old. This bag packs down fairly small, specially when used with compression straps. I didn't used this while backpacking yet but traveled with it in my backpack and it doesn't use up too much space. For the price, and with the specs on this bag, I found it to be a great deal.
