Now for years I've been wearing this same set of Life Brand by Jockey Sculpted Pocket Briefs because they were the right blend of materials, were sufficiently stretchy, had a nice pocket to hold things in place and are still remarkably durable. Hey, I tried to find others, but ended up so bitterly disappointed that I damn near gave up trying to replace them at all. Now I can report that I've found a make that will do the job: Calvin Klein Body Micro Modal (trunks). The former (Life Brands) were a blend of cotton/algodon, polyester, and spandex which gave them a soft, cool feel, like cotton; and yet stretchy - much more than the 90% polyesters or the 100% cottons that had no give. In like fashion, these CK's are made of something called modal (90%): equally cool, soft to the touch, almost weightless. And the 10% spandex blend allows them sufficient "give". In fact one barely knows they're on. They're stretchy enough to give your "jewels" all the room they need with a nicely designed pouch (not one of those phony ones, but a separately seamed little "bag") and snug enough to keep everything in place. Looks like I've finally found some new undies. I think I'm gonna fuckin' cry.
