But when u put the packer its sits to high up and its a bit uncomfortable for packing and the packer moves all lot in the briefers thats the only problem
I purchase two different kind and out the two the cotton with the two button is my favorite. Be aware that that underwear run small so if you are normally a small get a medium. It’s awesome with any kind of packing you’re wearing plus the adult activities! I will be getting more!
My packer fits perfectly and I feel so sexy and manly
Paired this with the Axolom Noodie. They were comfortable and packed well, but the hole was high up and caused STP leakage.
It takes a little while to get used to the STP but it’s amazing. Great quality and design.
I’m very impressed with the quality. Everything is perfect and the delivery was very fast. Exceeded my expectations.
I love it! The only real issue I have with it are the balls they’re weirdly small.

If I could only buy one packer ever, this would be The One. It works at the gym or the pool because its compact design means I never have to worry about anything slipping out of place. The size means it will never make a bulge that's awkwardly large. And the solid, one-piece design makes it sturdy and easy to clean. It's a winner. If what you're looking for is presentation under clothing, this is the one you could use anywhere, anytime, in any situation, and it just works.
