Phrases like 'insanely light,' 'incredibly breathable,' and 'ultra-packable' are used a ton, but they're so apt when describing the Sea To Summit Micro McIII 28 Degree Down Sleeping Bag. Heavy-duty, quick-drying, water- and odor-resistant Ultra-Dry Down 850+ keeps you warm, while high-density, water-resistant 2D NanoShell with Nano DWR keeps you dry and comfy. The whole toasty package stuffs into a two-liter, extra-small sack that easily tucks into your panniers, backpack, or carry-on.

- Familiarity: I returned this product before using it
Bought this bag as an ultralight backcountry bag for use in Alaska for hunting and guiding fishing. My first impression was concern for the lack of quality in the bag for $400+ sleeping bag. Then I tried to get into the bag.... I'm 5'10 and an athletic 215lbs... I couldn't zip the bag around my shoulders. Either Sea To Summit has been overly generous with their stated size dimensions or the bag I received was flawed as the shoulder circumference was not 57" nor was the foot 37". This is literally the skinniest bag I have ever seen. I returned it for the Western Mountaneering Terralite bag and couldn't be happier.
