Comfortable, but run big
Size: Small, Color: Red/Orange/Yellow/Blue
I'm a small guy and I purchased size small. The underwear are not bad. Great if you're a bigger guy or if you have a really big butt. If you're on the smaller side or skinnier though they'll fit a little loose. My butt is pretty big, but it doesn't fill out the back completely. Very comfortable though and the waist fits fine. Just a big backside. They don't ride up and so far they're durable. No fading in color and the material holds strong after many wears and washes.
