It is pretty awesome. I don't understand why it is warm enough on the bottom. They are 550 fp down. That won't compress near as much as 900 fp I guess, but it still compresses a good bit. Makes me wonder why my sleeping bags- even poorly compressing synthetic- have not worked for bottom warmth? I mean- Ok my Cat's Meow 20F Polarguard has worked, but not enough. So what is the deal with these?
But hey, if it worked, it worked. I may be getting some of these.
What is the weight of a pair? And the loft? Just curious.
