Not sweat pants. More like really comfortable, durable, slightly stretchy, super versatile, "regular" pants.
I've done pretty much everything in these pants. Short hikes, biking to work, camping, nice dinners, river trips, you name it. They're soft, just stretchy enough, cool, lightweight, and look good. The 'no sweat' material is incredibly comfortable against the skin and allows for plenty of freedom of movement -- much more than traditional pants. Love them.
