I am 6' about 185lbs..
I have owned many of the cherokee sleepers and overall they fit me. The arm length on the cherokee was a little short but I didn't care.. The shoulders were always a little tight but would stretch after a few wears.. Also the crotch area on the cherokee was a little high and ride up my butt/crotch but again would stretch eventually but honestly it was always a little tight in certain positions.
I bought the XL Circo Spaceship Sleeper yesterday. As soon as I got home I put it on and I was surprised, happily.. The fit is way better them the cherokee. The crotch area is lower so it doesn't ride up.. The arm length actually fits and doesn't ride up.. Shoulders are still a little tight but that will stretch like the cherokee..
The overall feel and quality is just as good as the cherokee.. Definitely worth the $12.99..
Wanted to add I have seen many post about going to Target to check if the Circo Sleepers are in stock.. You can go to Target.com find the sleepers and then check the availability of the sleepers at the Targets around you. That's what I did and the store had exactly what the website said they would have.
