So this past summer was my first section hikes on the AT and really backpacking in general. I hurriedly got all of my gear together over the winter and had researched and developed for about a year. Learned alot those first few trips and am starting to learn what works for me. However, on a unrelated car camping trip late fall with the kids I took my Rei 20 degree synthetic sleeping bag into 35 degree weather. Which i had not encountered while on the At. So with a black lab two kids and me in a tent with a hat on socks on sweat pants and a long sleeve tshirt and a patagonia fleece i woke oh and ****ing hand warmers in my pants pockets, I woke up cold like really effin cold. So heres my deal im like 5'10 250. Im built like a brick **** house so when trying on all these bags at rei by diff companys one thing stayed true the whole experience. My shoulders are broad and mummy sacks do not like me at all. So to combat this an Rei suggested i go for a xlong and xwide bag. Im not that tall i really dont need the x long but try finding a bag that is xwide and not x long. As a result this thing is physically comfortable a ****. However, I feel like the increased material and baggieness is prob not trapping my body heat as well. Is anyone else in this boat? I really just want one sleeping bag that is perfect . Now I know this is going to spark the whole quilt convo but my only dilemma with that is rei does not sell them so say i ****ing hate that **** and now im stuck with a 300 dollar quilt and nothing to sleep in or under. Rei u can return anything so thats what im saying. Im down for cottage company I just dont want to be mailing **** all over the earth back and forth any one with a similar structure have any advise. Thanks Zig
