the biggest thing i like about it is that i can shoot with my big winter jacket on, which, being warm will keep me in a tree longer. as sad as that may sound, its true for me. when i'm freezing i have a tendency to get discouraged. i prefer to be 'cool', not hot or cold. i like to have some thermals, sweats, and a hunting jacket under my 3d suit when its cold outside and i usually have to rig up some kind of sock or something around my bow arm to make sure that from any angle i won't get string contact. i've done testing with this and i have a lot more room now and that makes me very happy.
