Great support, comfort, and construction

These are great! The build quality is excellent. They provide great support and the material is very comfortable. I got these to replace my dwindling supply of original Sheath 1.0 single pouch trunks and they are a great replacement. My only hope is that they will be offered in cotton in the future, to meet a safety standard for my job. The Sheath company’s customer support is also exceptional.

Feel great!

I didn’t know if I would like these at first but they are great. I love the sizing. To be able to fit me even with my big thighs is just awesome and the fabric feels great. 10/10 would definitely recommend.
