Reviews

10/10!

"My husband has gone on and on about these. This specific type is perfect for work! (Compared to the “icon” ones that are made of fencel—which are more for everyday leisurely wear in his opinion). These are very durable and still very soft. They hold everything in place perfectly, as well ( —according to him). Anyway, we definitely recommend them lol. Please make some for females! Loungewear/ pajamas/loose fitting clothing - in the tencel material- would be amazingggg! Side note: My husband is roughly 225lbs, 5,10”-5,11”ish, wears a size 38 in most pants/ shorts, or XL in shorts not sized in numbers. He has ordered & bought probably 10+ pair of these, possibly more, and only ever bought size XL - and there always fit perfectly no matter which types he gets - so they are definitely true to size, for sure! (He always wears the boxer briefs). Hope this helps!:)"
