We got some new Wilderness Technology -10F down bags for 2017 and decided we'd see how they hold up! They come with a large cotton sack for stowing when not in use and a large stuff sack for travel. I found it packs down into a Sea to Summit medium eVent waterproof compression sack that I like because when you stuff it and compress, the air can exit from the bottom side and makes the whole process of wrestling a whale into a tuna can so much easier. Also, of all the things that I don’t want to get wet, my big down sleeping bag is top of the list. Our first couple of times, we tried them out in a controlled indoor setting. We wanted to figure out the mechanics of the bags without any dire consequences, but they were too warm at home we had to take them to colder locales. So far, they’ve been a treat and have held up very well. Read-on for details.


First adventure: Ice-climbing weekend in Cody, WY. I wanted to try out how the bag ‘fit’ in a cold environment without fully committing to sub-zero temps. As a 5’6” woman, I had always been told to have the bag fit snugly so it was less room to heat-up and less weight to carry. Even with the extra foot and headspace, the bag kept me plenty warm in a cabin with only minimal heat to keep the pipes from freezing. I was so thankful for the bag during those pre-dawn wake-ups!

Second adventure: Cabin floor in Canmore, Alberta; more ice-climbing. Time to zip up with someone else and see how it worked for two. Sometimes the process of getting two sleeping bags to wed is the most aggravating part. Not with these Wilderness Technology bags! With a right- and left-opening bag, the zip came together SO smoothly and all the way to the top. No wrestling with gear; the easy pull tab at the base of the zipper was also helpful for getting it aligned and started swiftly. We found that two ‘regular’-sized bags offer enough room that we could still sleep separately (and stay warm) with the top and bottom zippers zipped, but had the advantage of cuddling closer as desired. With the top zipper un-zipped, I could wrap up and stay warm when my husband said he was over-heating and had to kick-off the covers. Win.

Third Adventure: Nepal. 16-day trek from Lukla north and west to Gokyo Ri, east over Chola Pass, then to Everest Base Camp and up to 18,200’ in elevation. Springtime in Nepal brought Rhododendron and mustard green blossoms while ~10-12,000’, but it also brought snow, wind, and cold. I loved the warmth and COMFORT of the Wildydown -10F bags--even while sleeping in a t-shirt until our highest over-nights.

In warmer temps, the bags were useful as blankets, but as we gained elevation, I really appreciated the room to move and change position in my sleeping bag while it was zipped up. With no heat-- and wind often blowing through windows--stretching, changing clothes, or reading and writing all became reasonable activities in my ‘regular-sized’ bag. I may never go back to a snugly fitted sleeping bag.

Fourth and latest adventure: 2 nights on The Root Canal, a glacier that shoots off the east side of The Ruth Gorge in the great Alaska Range. My climbing partner, Katie and I climbed ‘Ham and Eggs’, an ultra-classic alpine ice route on The Moose’s Tooth in a ‘Smash and Grab’ style: flying Portland to Alaska and back in <72 hours round-trip. This was probably the true test of the Wildydown -10F down sleeping bag thus far. We snow-camped on the glacier and had 2 women in a 3-person tent that were tired and hungry, but stoked. The first night I was plenty warm and again appreciated the extra room in the bag for all the electronic gear I was trying to keep warm with me. I’ve done some cold damage to my feet in the past and find that after a full day of climbing, they’ve have been pretty beat-up, and it can be hard to warm them--regardless of the bag I’m in or the layers I put on inside it. This was true this time as well. At first, I put my down booties inside the sleeping bag, but it didn’t help so I discarded them and warmed water, put it in a Nalgene at my feet, and my toes warmed quickly thereafter.


Bottom-line: I haven’t been cold in this bag in single-digit (Fahrenheit) and very likely below-zero temps. It’s a great deal for an expedition bag that’s easy to use and has a lifetime guarantee. I’d recommend it, even as a 5’6” woman at ~140 pounds.
