i love them. i’ve been slowly swapping my underwear over to sheath. it keeps the twig off the thigh. no chaffing or excessive sweating. i wish it were a tad cheaper but sheath offers discounts which is good

Cotton fabric has too much elastane
I like that you have a cotton product. However, I did not like the amount of elastane. The medium feels tighter than the modal medium. The large also feels tighter on the legs than expected for cotton. I prefer 100% cotton. I guess that you want some elastane to get it to not sag. However, maybe some elastane, but less than that in the modal fabric. 5% would be a compromise.
