From the fabric to the draw strings there are nothing but good reasons to like these shorts. They feel light and breathable, but I don’t feel exposed in any way from the liner.
I have a little over a 34” waist for my real measurement. I’m 176cm tall, or just over 5’9.” I weight 165 lbs, so I’m on the higher end of slender-ish — meaning I enjoy my pizza. That put me in a size medium. The large was too exact on my mid section to grip and stay up during practice, but the medium has a comfortable fit with plenty of give. The fabric gives it so much stretch sizing down can be a good idea.
Best of luck in your purchase!
