When comparing these to the David Archy Bamboo Boxer Briefs the pouch isn't as roomy or as "pouchy" - it's more like just a bulge. That's very unfortunate because the pouch is the main reason I switched from Calvin Klein micro modal boxer briefs to David Archy. In theory this product and the David Archy Bamboo boxer briefs should be essentially the same thing: same cut, same sizing, etc except for the fabric. In reality that's not the case. I don't know if I got a bad batch or what, but the pouch just doesn't cut it.
As far as the material is concerned, I would say it's slightly more cool than modal or bamboo and it does seem like the fabric wicks perspiration away from the body pretty well.
