Well Thank you for your response. I have reveiwed your post and done some homework. The Wm UL. in reg length has a 59 inch girth. Exact same as my Sub Kilo from REI in Long length. Hench same issue with shoulder girth. Marmot Helium is 5 inch wider girth in reg length. However I dont like that it is made overseas! I am going to hold off a couple monthes till i try out sub kilo in my new hammock. Perhaps I will try a quilt. If not mabe the wider WM bag I willgo with. I am union employee ,so Made in USA means allot!
