Vulcan™ UnderQuilt

The dual-layer Primaloft kept me perfectly warm even when the temp dropped to 40°F, and it packs down surprisingly small for how much insulation it provides. I stayed dry through a light drizzle too.

I hung this under my hammock on a rainy weekend trip, and the Primaloft layers kept me warm even when the temperature dipped unexpectedly. The fit was snug around my hammock's bottom, blocking drafts nicely.

The two layers of Primaloft insulation really do the job — I stayed warm all night in my hammock while my buddy in a regular sleeping bag was shivering. Packs down smaller than I expected too, which matters when you're carrying everything on your back.
