Works for Me

By Ranked #97 - Sleeping Bags May 11, 2011

I like this bag so far. I don't like it as much as my Phantom 32, but that should be a little obvious. I would've gotten the Phantom 0 but I wanted something with synthetic insulation just in case it were to get wet since my purpose has been winter alpine climbing. It's close to being too small for me. I'm about 5'9" and have size US 11 feet. My feet seem to touch the end of the sleeping bag. So far, whenever I've slept in this bag, I've gotten pretty cold. One night my feet even felt like they got close to numb or something. The night my feet got so cold I didn't have any insulation between me and the ground (I happened to grab the wrong ground pad and didn't have enough extra clothing to put under my feet). So far, the outings I've taken it on have gotten close to zero degrees but more like 10 degrees. A couple nights I even got it a little wet all around and it still kept me reasonably warm (meaning I was cold be was able to at least get some sleep). I like the short zippers. My bivy sac is the Bibler Big Wall bivy, so its zippered entry is even smaller. So I don't notice the small entry that much. It closes quite well over my face except for all the cords that slide against my face all night. I've modified my sleeping arrangement with this a bit. For temperatures around 10 degrees or so within a bivy sac within a snow trench, I definitely wear additional clothes within this sleeping bag. I wear lightweight down booties on my feet. I make sure I have a full length closed-cell foam pad. I definitely wear long Johns (top and bottom). I'm considering some puffy pants. I wear either a lightweight down jacket or fleece top. I also wear a sock hat and face guard thing that goes around your neck. I have also worn mittens...hahaha. Well I guess that's what all it takes for me. But that's all stuff I bring anyway for day and night operations.
