Cozy sleep system
I got to use my thermodown 30 quilt this weekend and I could not be happier with its performance. The weather got down to about 45 degrees and I was perfectly warm with a pair of merino leggings and long sleeved top. It packed up compactly and quickly into my backpack. Very happy with this purchase!

Light, packs small, and so warm
I haven't used this in the really cold yet, but using the 30 degree bag at about 40 degrees I needed to poke my feet out and be down to my underwear. I do sleep hot though, so others might have a different experience. This has transformed my backpacking coming from a large and heavy regular mummy sack.

Perfect for my needs
A perfect quilt for my needs. I used it with temps in the low 50s in a bivy and was incredibly comfortable.
