AXOLOM STP Boxer 1.5" O-ring Navy Blue

Riley Fray
Great for play. Less great for all-day wear.

It's so rare to find a boxer design that can be used to pack, with an stp, and with a pack and play, but the o-ring, packing pouch, and button front allow a wide range of uses. This boxer is perfect if you want something versatile. The only reason I don't give it five stars, is that they ride up very quickly into wearing them and eventually become a little uncomfortable. It should be noted I have sensory issues, so this may be a uniquely me problem, but I felt I should mention it none the less.

Hi Riley,
Thanks for your review!
We are always willing to hear from different voices, improve our products.
Best regards!

The harness boxers are a perfect fit and are made from very comfortable material. They hold the STP I purchased perfectly. Would definitely recommend getting a pair if you purchase any of the products from here.

Pack & Play

My goodness this is a 10/10. Maybe not the intended use BUT let me tell you. If you’ve been searching for something affordable that’s great for packing and can keep up with playing this is definitely it. I tweaked mine a bit and had to sew on a pocket to keep the packer from touching me directly all day (super sensitive down there it happens with every packer) but that’s just a personal thing. Super comfy, solid color choice, and cute logo. My girlfriends love it and I love it. Can’t wait to get more.

The thinker and au natural realistic

C4 looks a bit lighter on the store and the colour 1 of au natural isn’t as matte as on the website also the thinker cup is a bit small and placed a bit weirdly
