Embrace the caterpillar in you!

With this bag, I feel and look like a squashy green caterpillar. Zip it up, snuggle down, and after the coziest sleep in the coldest temps, you'll emerge in the morning a beautiful butterfly. That is if you can bear to come out!

I'm a 5'4" smaller woman. I sleep cold and this bag works well for me in even the coldest of temps. I've still paired it with a liner for truly -20°F temps and that works well in a four-season tent. 

Zipping all the way up can be a slight challenge—it's a bit of a squeeze, but comfy once enclosed. The baffle that comes just over the shoulders works great for keeping the moisture from breathing out of the body of the bag when all zipped up. 

So far no complaints about durability and construction, but it's only been out a few times and I've babied it well. Don't want to unnecessarily wreck a bag this nice (and expensive!).
