The exterior length is 80" and the interior length is 78". This bag is recommend for people up to 6' tall. The reviewer may have been sent the wrong bag and got a short by mistake.

When mine recently arrived I tried it out in the house. It will NOT fit a person six feet (6') tall. I am five-feet-seven (5'7") and it fits me perfectly. It will probably fit up to a five-feet-nine (5'9") person but no taller than that height -- if you still want to use the head cover and have the body material cover your chest.
