These are your standard-issue American Apparel yoga pant. They are now a staple of my lounge-wear. They are stretchy and comfortable, so even though I wear a 14 in North Face, I can easily wear a L in these. Ample in length, they work for me even though I usually wear longs (5'7").
Got these to replace some pants that I had for a few years but were getting worn out. These were great! Slim, comfortable, highly recommended, until they developed a hole in the right thigh (nowhere near a seam) all on their own :-(
These are super soft and comfortable. They are yoga pant style more than a sweat pant which means they are rather form fitting. The roll over waistband can be folded as much or as little as you like, and there is no uncomfortable elastic band. I was happy to discover that they are American Apparel (another wonderful company) screen printed with a Moosejaw logo.
I bought this because it looked quite wide fitting but they ended up being quite snug. I'm 5'8 165 pounds and the XL looked very tight on me. These unfortunately had to go back. You probably won't have this problem if you have thin legs.
