Being somewhat overweight...it is a pain when my regular skivvies' waistband rolls down, proving constant discomfort. I find these Exofficio's the ticket to comfort, especially for some of us with the done-lop syndrome (done lopped over the belt).I try not to look at myself in the mirror, but they sure provide all-day comfort. Easy to wash and dry each night and be dry the next morning, when following manufacturer instructions! I have four pairs with different colors.As for my weight, I'm on portion-control now instead of the traditional diet. Shooting to lose 5# per month.I use this underwear for business travel. I take some hand soap tomwash them out and by morning they are dry. Three pair and I can stay a whole week without a problem.I bought three or four pairs of Exofficio briefs when I went on an African safari A few years ago. They were size 2X and they fit well. I saw These on Amazon I bought a couple more pairs . Same size but they are too small. I am 10 pounds lighter. I wore one so I could only return the other one. They are also Lower below the belly button making them feel almost like a jock strap not like my old pairs. These are uncomfortable. The material seems ok.Comfortable but they need a whole day to dry would not be able to wash at night and wear in the morningNot really a fan of these. A little small, and the cut on the thighs rides up a little too high for me. They are a comfortable material though.These are lightweight, fit well, and are very comfortable. They dry quickly, as advertised. But, if you're a little old-fashioned, be sure to read the fine print in the description. They are "flyless." That takes a little getting used to.Too expensive for the productI took two of these briefs on vacation and hand washed one each day and the dried nicely overnight even in 90% humidity. Excellent product, I plan to use these on my planned sailing circumnavigation.
