I love Dockers briefs and I like to wear trunks also so I thought I would give these a try and I'm glad I did.  Admittedly they felt a little weird at first, like they were 95% lycra and 5% cotton, instead of the opposite.  However, after a couple of washes they've changed to feeling and looking more like cotton.  They're an excellent fit, with a firm but giving elasticity around the legs, a very comfortable pouch, and a wide, soft waistband.  They look great too, my girlfriend loves them, and the color choices are decent.

*Notes:
1. If you are buying these for someone else; they are not boxer briefs, they are trunks, which are shorter (in-between a brief and a boxer brief).
2. They are also 'stretch' trunks, so there is a small amount of lycra/spandex type material in them, so they will feel a little different at first.
3. They have no fly.
