Try these under your favorite shorts and a signature graphic tee on a hot summer day.

Flex performance underwear uses revolutionary fabric to give you versatility and variety, with wicking technology that keeps you dry in all the right places. The 9-inch, longer length Flex trunk has a low rise with a longer inseam if you need more coverage. The shorter length trunk has a 3-inch inseam and flat seams, perfect for wearing to the gym under athletic wear and shorts. If you want something in between, check out the regular length Flex trunk with a 6-inch inseam.

American Eagle Outfitter's version of the boxer brief is the 6-inch classic trunk-- they are made to move, with a soft jersey knit, a signature stretch waistband and a 6-inch inseam. The low rise trunk is shorter in length with a 3-inch inseam and sits lower on the hips to perfect your silhouette if you're wearing a pair of slim-fitting, lower-rise pants. If you've always been on the briefs side of the boxer vs. briefs discussion, you can find the classic brief here, too. A contoured pouch, sleek stretch jersey and a soft elastic waistband accent every brief. Select from color-blocked neutrals or prints that suit your mood.
