 Cred: 169 | | Light weight, good 800+ fill power, true to temp rating (I've slept in it inside a tent with a CCF blue pad down to 10*F, I got cold through the ground due to low R value of pad) |
| My model has the 1/2 zip, annoying on warmer nights. A full zip would have given this a 5 star, (but I've never slept in a WM bag for comparison) |
|
 Cred: 25 | | Weight, good temp rating, very compressible |
| I'm neutral on the half zip (no longer an issue) |
| Western mountaineering, Feathered Friends, Montbell. Any of these companies make top notch down bags |
