“I'm 5'10”

“Runs small, think about going to the long if your a few inches shy of 6 foot. I haven't maxed out the temp rating yet so I'm not sure about the temp rating on this bag. Part of the shell was sewn into the zipper so it's about 2" short of zipping all the way up. IF it didn't cost me a cent, I'd return it for a long and hope that it wasn't poorly constructed like this one. So far, it has been a warm bag down to 20F and the price was the largest selling point for the -20 bag.”
