Born Aviation Men's Remove Before Flight Boxer Shorts-Red-Medium

Couldn't find this at Airventure, so kudos to Amazon. Waistband is snug, but the rest is a very roomy fit, almost like a skirt with a divider.

Good quality I gonna keep but the size m is large

He loves them! They are very soft and comfortable and they fit perfect. Usually a size medium in boxers and I ordered the medium so they are true to size
