Once again - a great bag from Mountain Hardware. This thing packs down to the same size as my down 45 bag. Very light. Great in all aspects. Bought this for my 11 year old son (and of course for me too!). He has no problem getting it into the stuff sack. The quality is unreal. I am 5'6" and ordered regular size. More than ample room. According to my son it is warm.
