An excellent bag. Extremely light and warm beyond its rating. If you thrash in your sleep or sleep on the ground without a pad, this is not the bag for you. It is not wide and has a delicate shell. I am 6'5, but sleep on my back, usually in a tent, so it's great for me.

This review if the the TNF Thunderhead. Similar Temp with 3D fill, except from what I gather a stronger shell. Great all purpose 20* bag. Stuff's relatively small and kept me warm in a 20* walk in freezer overnight although there was some frost on the bag (from my breathing I assume). All in all I am not dissapointed. I will be using this bag for the beginning of my AT thruhike starting 3/1/01. If I had to buy another one I would have gotten the Big Felle cause it is kinda tight in the shoulders (60"). I did cut the quick cich loop off, because its hard to open the hood back up after its cinched.

Kelty Hollofil II 0*deg. Horrible, lost loft quickly, didnt perform as advertised.

Purchased this bag to replace my Snowshoe. Slept cold around freezing several nights in damp cold apline conditions while on bivy. The 3D has high-loft but doesnt seem to trap as much air as Primaloft. Stuffed much smaller than my old Snowshoe. The diamond shell is great. Sold this bag when I discoverd Integral Designs.
