The title pretty mush says it all, I bought this bag because it was light and packed small, but mostly because of its advertised "super stretch". I hate being confined in a tight bag so I went for it with this one. I have to say it wasn't really all I had hoped for. Really it doesn't seem all that stretchy. But when you get into it and start squirming around you start to notice that it really does do a pretty good job stretching, it really doesn't seem all that confining. I think I just got my hopes up a little too much, it isn't quite as stretchy as I had expected, but overall much more forgiving then a normal bag. Warmth wise this thing is hot. Granted my only use of it was 14 nights throughout the Patagonian summer and it never got down to the 25 deg the bag is rated, so I generally slept with the bag unzipped.

This is by far the best t-shirt I have ever bought. I wear this thing any time I think I'm gonna break a sweat, running, biking, climbing, hiking, my record is 9 days straight, day and night, backpacking. By then it started to hold a bit of odor, but all my other polypro would have reeked after only the first couple of hours. The skin tight fit is amazing, the wool is really soft and comfy, can barelt even notice it. Well worth the investment, but watch the sizing, I generally wear a medium to large normal shirt but I heard these run small so I got a large and it is skin tight. I also bought an XL and it fits more like a normal T. I also have the long sleeve, and love it even more.

All in all I would say these are an awesome pair of boxer briefs. They're comfy and not too hot or too light. They fit well and all in all I like them alot, I think they definitely beat out Ex-Oficio's, mainly because these actually resist odor, Ex's don't come even close in that department. I like 'em!
