We believe men’s fitted underwear should keep everything you’ve got looking awesome, whilst keeping you comfortable no matter what the state of affairs.

Women asking to see your Stiffies is something you’ll learn to deal with.

We went through 50 prototypes making slight adjustments in the seam positions & materials to make your backside and front side look as jaw dropping as possible.

We even added an optional usage pocket that stops clingage, reduces doubling over if you go big and as a bit of a bonus, it makes your package look mysteriously massive!

My husband put them on, looked down & goes “S#*t they make my package look good”
