What is the most comfortable and joyful feeling underwear that you have every put on?

when those are unavailable, my second choice would be the bamboo ones MJK used to make. they were the best, aside from sizing inconsistencies.

My favorites are Flint and Tinder trunks. I used to buy a lot of CK but concluded they weren't worth the extra cost compared to Fruit of the Loom boxer briefs. The Flint and Tinder are worth the extra cost.

I been wearing quite comfortably the uniqlo boxer brief low rise. I got a little ass so they fit perfect. They feel even more great after they been washed because they tighten up a bit.

My balls sleep very comfortably and stay in place.

Let me tell you a nice story about my underwear days.

One time I wore Hanes white briefs and that day I happen to eat 3 burritos after school. The most unfortunate thing happened on my way home, I shitted on myself. I couldn't make it home to drop my 8 pounds of horse shit. So my undies turned black. I washed them good and I made sure to remove the corn embedded on them, and they turned brown. They actually looked dyed. Needless to say I wore those underwears and with pee stains they look like an animal print like Leopard. They were my favorite underwear but that was the day I said goodbye to briefs.

CK X-Micro Low Rise Trunk .. got a collection of about 15 pairs of them.
