Are you a tighty-whitie kind of chap, or more the moisture-wicking athletic boxer shorts guy? When it comes to underwear, men clearly don't have the sheer number of options women have. Choices tend to fall into three not-very-creative categories: boxers, briefs, or boxer briefs. But no need to, er, fly by the seat of your pants: There are plenty of stylish eco-friendly choices for the green guy out there?composed of fibers including bamboo, hemp, cotton, and linen.

Why We Like It: Men?s Active boxer briefs from Patagonia are designed for outdoorsy types: They?re lightweight and comfortable enough to wear under hiking layers and moisture-wicking technology keeps you cool and lets the skivvies dry quickly after being washed.
Eco-Factor: The briefs are made from 54 percent recycled polyester and, if they ever wear out, Patagonia will take them back as part of the Common Threads Recycling Program.

Why We Like It: Toasty Boys thermal sleep shorts do just what they say—keep the boys toasty warm during even the chilliest winter days and nights?yet are still thin enough to wear under jeans.
Eco-Factor: The shorts are made of 100 percent organic cotton, so you don?t need to worry about pesticides?and, who knows? They might just be warm enough to let you turn down your heat this winter.

Why We Like It: Rawganique?s hemp boxers are a looser alternative to boxer briefs?the company recommends wearing them as pajamas or "house shorts" instead of just underwear?with a low rise that keeps them hidden under pants.
