However, Outdoor Vitals' StormLoft 15 Down UnderQuilt makes moderating your sleeping temperature easy. Paired with a Hennessy Hammock, this setup is nearly unstoppable.

Final Thoughts:

If you're not interested in getting seriously into backpacking or camping, there are simpler sleep systems. But if you're not intimidated by the hammock learning curve, the StormLoft under quilt does a terrific job of helping you retain warmth. Outdoor Vitals does a terrific job of providing quality products. Overall, Outdoor Vitals' 15 degree StormLoft performed impressively well in the backcountry. 


I spent a few months testing this under quilt in Colorado's backcountry on various backpacking trips. Temperatures ranged from the low 30s to the mid 40s. I typically sleep really cold, and this quilt never disappointed me in terms of warmth. Conditions were dry. While this is my first under quilt, I'm an experienced hammocker.
