re: What’s the most comfortable underwear?

I've tried a lot of underwear. Once you move to boxerbriefs from boxers, the next step is separate pouch underwear. It's done in a lot of different ways. No-one does this better than David Archy. Instead of sewing in a separate pocket like some or putting in "dividers" like Saxx, they simply shape the underwear so that the fabric pulls snug between your nads and your thigh. Their micro modal underwear ( Amazon LINK) is long enough not to creep up and are amazingly comfortable in a way that you just won't understand if you think Ex Officio or any other regular boxer briefs are good enough and haven't tried anything with separate pouches.
