The first thing I thought of when I slipped these bad boys on, Ned Flanders couldn't have said it better himself.  "Feels like I'm wearing nothing at all!"

These are extremely soft and comfortable, it literally felt like I wasn't wearing briefs at all.  I think the big reason for that is that the strap isn't super tight.  That could be good or bad.  You don't really feel the elasticity, hence more comfortable, but I suppose some wearers could get the sense that they are constantly slipping.  I didn't.

The style is really great too.  The Puma logo is a pretty cheap iron on decal sort of thing so that'll probably crack/peel off after a few washes (if that sort of thing bothers you)
