These are the most comfortable sweatpants you can buy. When I look for sweatpants they've got to have the elastic cuff on the legs because I use them for running. Have you ever tried running in a straight-leg pair of pants? Feels like you could trip over them with each stride. Also they have to be durable. Bought a different brand of sweats a couple months ago and tore the crotch right out of them while doing squats in the gym. Can do without that kind of surprise. The Russells are durable and have reinforced seams. And then there is the comfort factor. One word..... FLEECE. Would recommend to anyone who runs and/or works out religiously. I would buy a second pair but springtime is here and springtime in Florida is, well.....HOT.
