Backpacking overnight it got to 23 degrees stayed warm. Very pleased for the price it is a great bag.


  • Price
  • Warmth


  • Weight (little heavy but for the $ it was fine)

Warmth: at 23 deg. it was great.

Fit & Comfort: I am 6 foot and I felt comfortable.

Packability: Does not pack as small as other bags I have, but at 600 down it did fine.

Construction & Durability: Only used it 3 times so far... we'll see

I perfer darker colors. The bright color will show small stains I am sure.

Source: bought via a "pro deal"
Price Paid: na

This is an awesome bag for the price. Well made with durable zippers, nice features, and rated to 0 degrees. Got this bag for my wife who is ALWAYS cold, and she absolutely loves it.

Haven't used it in single digit weather yet but works great in the low teens. I would recommend this bag to anyone looking for a nice down bag to keep them warm on a budget.

Price Paid: $120

I was given this as a Christmas present last year. I did a lot of research and thought for the money it would be good. It has exceeded my expectations.

I just got back from a trip in November in the Smokey Mountains with two friends. I slept in this with just my long underwear on and no shirt or socks. My two buddies slept with all their clothes on in their bags. I was actually hot — I had to vent air out every once and a while.

Awesome bag for the money.

Price Paid: $130
