Simple but great bag. Forthright about the temp rating. Light and packs well for a synthetic. Cost effective.


  • Lightweight
  • Packs small for synthetic
  • Comfortable

Warmth: Tells the minimum and comfort rating on the bag 25/40. Does well with the rating. Warmth is distributed evenly.


Fit and Comfort: The material is very comfortable. It is roomy in the torso. Leaves off the hood to reduce weight. 

Entry and Exit: Very easy in and out. Zipper doesn't stick.

Moisture: I've never had an issue with moisture.

Packability: Packs down to 8 X 10

Loft: Average loft if you shake it out.

Ease of Use: Everything works great.

FeaturesThe draw string is made of elastic cord. It cinches down well and since it's not static it allows you a little more breathability as you toss and turn. Doesn't sound like much but it's surprisingly pleasant.

Construction and durability: Has held up fine for years.

Conditions: I bought the bag used and have continued to use it for the last 3 years. It's holding up great. 

Source: bought it used
Price Paid: $15


I think you could write an inspiring forum post about how much gear you're able to get per dollar versus the average consumer!
