Crossfly IKON X Men's 6" Boxers - Your First Pair - Silver/Charcoal

Rick Clark
Really good - almost great

These are very comfortable underwear. The fabric is very supple and comfortable. My very minor complaint - and it is truly minor- is that I would prefer a little snugger support for the boys. I expected the “crossly” to create a bit more of a supportive pocket. Instead, it’s really more of a decoration. They ARE very supportive, though. I’d definitely buy again!
