Best underwear in the world. Seriously. These have all the best qualities of both boxers and briefs, and live up to the hype 100%. Not sure how long they last, because every pair I own is still in one piece. They seem expensive, but the last package of name-brand cotton underwear I bought started to disintegrate after just a few washings (warm water, no bleach.) I wear these at the office, when doing heavy work outdoors, as pajama bottoms, and (when it's just my Lady Wife and I ) to run around the house in. I have one pair of briefs in this style that I wear with the "interview suit" but I prefer the boxer briefs. I like the button fly better than the brief fly, but that's just personal preference.
I even bought "long johns" in this material as a base layer for my cold-weather outfits. SO much better than cotton. Survival experts will tell you, "Cotton kills" in cold weather. I even wear them with a dress shirt and khakis to my chilly cubicle in winter.
As to the claimed "no sweat, no stink" properties of these, for comparison my polypropolene "expedition weight" long underwear gets damp (not soggy) and STINKS after outdoor exercise- bad enough that it has to either be washed immediately or banished to the basement in a laundry basket.
