These are what are considered "full seat", or "drop seat" boxer shorts... They're the ULTIMATE in comfort.
They're made the way men's boxers were made 50 plus years ago... The waist rides on your natural waist, a bit higher than what's current.
The "full seat" part means that there is a separate strip of material that's sewn in the seat, there are two vertical seams that run down from the waistband and end at the bottom of the leg openings... What this allows, is for the seat to "lay flat" when the wearer is sitting down... So there's no binding, no pinching, no tight feeling constriction.
In fact, for those who've never worn this type of undergarment, you'll probably forget you're wearing underwear about ten minutes after you've put them on.
The material is cotton. The waistband is pinch pleated cotton over elastic.
If you're anything like me, these are a real welcome change from "modern" low rise shorts that seem to want to fall off every time you walk... They're the ultimate in all day comfort.
