I originally got a north face sleeping bag that said was very roomy but I could not bend my legs in it. I purchased this Echo Park sleeping bag as it said it was roomy. I am a side sleeper and toss and turn all night and usually have to have my legs bent to an extent. I haven't used this in the field because I'm waiting on a sleeping pad but my initial impression is this bag is very roomy and the fit and finish is excellent. I also added the extension to it. I'm very excited to try this bag.
