They give space for the ties and the ring is in the right spot no complains.
Unfortunately, the quality is poor.
The buttons on the underwear fell off as soon as I unpacked them.
And after washing them eight times, there are already holes...
Smooth and stretchy. They work beautifully with The Thinker. If you are looking to use an STP covertly/handsfree, keep in mind that you may need a harness as well. The boxers do not hold the packer flush enough to my body that I can use it without holding it or wearing a harness.

I think these are my favorite boxers for packing. Very versatile, great fit, nice fabric. I would love to see one made with an extra pouch, instead of the elastic for regular packing, then these would be all I would ever buy.
I love this STP and have had no issues. It took a little while to learn how to use it but it was totally worth the wait. Great product I will definitely buy another style down the road.
I bought it just cuz I wanted to finally try an STP. Really very easy to use, I got it on the second try! For me the problem is that turns out I just don’t like having anything in my pants. Don’t get me wrong it was not uncomfortabel, but personally like it just bothers me that there is smth there all the time even tho it looks good. Also, I don’t get how ppl use STPs in general cuz like, I still want to wipe whatever drops are left on me so they dont go in the undies.. like that’s just gross. So the product is truly great and good quality but I don’t know when it will come in handy for me.
They fit and feel great which is why I have bought 3 now. I only have one issue with them and that's the front flap just doesn't stay quite tight enough to pack up properly with the Godor STP (which has to be packed upright) without looking like you're erect if you feed it through the loop. I have to pack it in just the pouch and hope it doesn't fall out. The pouch is deep enough I've made it work, but it would be nice to be able to pack it properly and it fit tighter to the body more naturally. Just a suggestion for future designs. Otherwise, absolutely great product.
It's comfy and it works js but I do want to order another Willie tho I have been wearing mine since I don't wanna take it off I appreciate axolom
When it's warm, it feels natural
