"I've tried many different brands and these are by far the best. The fabric is so soft and they hold up really well. The horizontal fly is also genius. Highly recommend!!"

Super functional horizontal fly

Best fly option for men’s underwear is the horizontal fly, less fiddly for exits and provides better support.

Yep

The nuggies are nicely snuggled.
As before, I’m a happy Chappy.

Love the colour on these. And so far they’re holding up really well! Much better than my bamboo ones.

The best!! MicroModal is now my favourite fabric, and the fly on Debriefs is so much better than a vertical fly. Highly recommend
