Lightweight, warm, odd, and lightweight.I've spent over 30 nights in this strange rear entry bag and its treated me well. I've taken it down to the low 30s and did start getting a bit chilly. However, it was on a college backpacking trip involving a bag of wine and a lost sock. If you have two socks on, perhaps a fleece, and a warm loincloth, this bag can probably make it down to its rating. Ultralighters rejoice, no gimmicks like zippers (HAH) who needs em' anyway? Oh yeah, it works great in the summer as you can put a limb or two in or cuddle it without having a heatstroke. Neat! If you're willing to take a risk, go for this creature from the black lagoon. Be warned, it definitely is NOT for everybody.

I really like it!I got the Haven because I wanted a lighter sleeping bag for packrafting trips. Its met the need very well so far. Light and warm. I have had to use a fleece sleeping bag liner and wear a couple layers to get it to perform to the 20 degree rating, but that's the only real complaint. Getting into it isn't any more awkward than getting in one of my sleeping bag liners. You get used to it pretty quick. It works well with my NeoAir All Season using the straps and buckles on the bottom, but is noticeably less drafty in my old Thermarest Prolight that fits inside of it.
