Sleep warm all year.

A true winter sleeping bag, the Therma-a-Rest Women's Adara HD Sleeping Bag will keep you warm when the temperatures plummet with a comfort rating of 22-degrees Fahrenheit. Great for winter camping, this lightweight pack weighs just about 2.5lb, so it won't weigh you down when you're moving quickly through the backcountry. The exclusive ThermaCapture reflective lining captures your body's radiant heat to add warmth without adding weight or bulk. And for cozy toes, Therm-a-Rest's patent-pending Toeasis pocket gives your feet their own little chamber to make it easier to stay warm. Hydrophobic down will remain warm if it happens to get wet, and the zoned insulation places 85% of the fill at the top of the bag, leaving the Synergylink mattress connectors allow your mattress to do most of the insulating between you and the ground. The full-length zipper is backed by an insulated draft tube, and the bag's cinchable hood with draft collar let you hunker down for warm night's sleep in the depths of winter.

Warm, fits well.

  • Familiarity: I've put it through the wringer

I've used this bag on backcountry snowboarding trips and late fall backpacking trips. It's cozy and warm- my favorite feature is the warm toe pocket at the bottom! I usually pair it with the NeoAir Xtherm and have used it down to the low teens and stayed warm. On the coldest night I made sure I went to bed warm (did some jumping jacks).

  • Familiarity: I've put it through the wringer

I bought this bag from in August of 2015, after I got cold while on a pack trip for work. I've slept well most nights in it, although I'm still not sure the Thermarest-tie in works super-well if you're a restless sleeper. You can still easily roll or shift to the point that cold air comes in the much thinner back (contains reduced fill to save weight). I noticed cold wind seeping in the seams bordering the back when I was camped just below Mount Koszciusko (the highest point in Australia) in very windy, chilly weather after I rolled most of the way off my sleeping mat. However, my main concern here is the durability. I have used this bag probably 30 nights since I got it, and the threads on the baffles on the inside of the bag where my heels rest is disintegrating. I stitched up a seam that came undone, but there is nothing I can do about the stitching of the baffles I compared the wear to the wear on an REI and a Marmot bag I have owned for probably a dozen years, and have a lot more nights in, and they show no such wear. I have never worn anything to bed outside of socks, and the obvious failure of the thread on the baffles in the area of my feet lead me to believe the materials and construction of this bag are sub-standard.

Update: I contacted Cascade Designs and they replaced this bag, no questions asked. They used a different thread, the fabric has been updated and I anticipate no problems with this bag. I recommend buying Cascade designs products because of their excellent customer service.
