I ordered one for my boyfriend to try
1st impression fabric is very soft and smooth
2nd is super light
I ordered for him to use in running I like it initially let's see if he does
Very lighte and softes trunk looks like good quality. Nice and discreet color.
Finding the right fit was always a struggle for me. Either too tight or too loose. These trunks solved that. The stretch and support are spot on, and it’s really true to size
Everything about cottosilk products is amazing.
Fabrics, weight and comfiness, is unmatchable. I’ve ordered twice in the span of 5 weeks.
LOVE IT!
