I have the Big Agnes Lost Dog 15° long/wide model... I'm 5'11'' and 140 lbs... it's WAAAAY too big for me... I feel like it's really bulky in my pack and I could easily save space and weight getting a different bag... but I really like the bag... the footspace is awesome... the pad cinch design is great (I love that my bag and pad are attached, makes sleeping so much comfier)... I just wished it packed down a little tighter... it's hard to get my water bladder in its sleeve while my sleeping bag is in the bottom compartment... my question is, do I get another lost dog 15° in the regular/regular size (6'' shorter and a lb lighter) or should I just get a new sleeping bag all together?
