Gear Review: Sierra Designs Zissou 15 DriDown Sleeping Bag



I'm not one to buy new gear until I absolutely have to. My old sleeping bag had served me well on the Pacific Crest Trail in 2011 and on many trips in 2012, but it was getting worn down. After hearing about the DriDown bag from Sierra Designs I figured it would be worth checking it out. I've never had a down bag before, but I was impressed by how comfortable it was. While laying on the floor of REI, the thought of where I would first use this sleeping bag ran through my mind.

Overlooking Spring Basin Wilderness
Spring Basin Wilderness is where a good friend and I traveled to. The temperature had been dipping to around zero the few days before we headed out there. I wasn't sure if my new 15 degree bag would even come close to keeping me warm over a few chilly nights in the Oregon desert. Oddly enough with lows of 13 and 7, I was still comfortable enough to sleep all night. But I wouldn't suggest going below the temperature rating of a bag unless you a back up plan to keep you alive if it's too cold.


The major selling point of the DriDown is that it retains loft ( therefore warmth) and dries faster than traditional down. I haven't been able to assess these claims yet, but once I do I will post an update. Overall it seems like a great sleeping bag, especially for under 200 dollars.
