Better than expected, I'm pretty big so I expected it to rip or have some problems when I walked, worked out well and the fact that it's a double short most didn't notice the sauna layer.It's been so far so good, no complaints yet. Will probably get a few more pairs.These shorts work as described. It will help you sweat and burn those extra calories. I wore them while working out and they were amazing. A must buy if you are looking to sweat and working out.The item was as described and arrived quickly. The shorts look great and really keep the heat in. It is 100% polyester and it is recommended to only hand wash. It's perfect for workouts and will help burn off those extra calories!I went for a hike and sweated my butt off!I really like the shorts, the quality is excellent and good fitting. I highly recommend to others.I love my new shorts; perfect no only for sauna but also for a regular workout session!Great shorts for that extra sweat! Fits as expected. Highly recommended.
