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 like the pouch for holding your business in place. Works great for packing.
4 Stars because the harness piece (it's like a loop "tab" on the front of the underwear) sits way too high, in my opinion, and is uncomfortable to use-- at least if you prefer to pack down. The website says it's okay to remove, but I'm a little disappointed about it. Maybe it'd work better for people who prefer to pack up.
Overall, I'm glad I purchased this to try and would recommend it.
