That convo with a guy at REI made me rethink my whole sleeping bag setup
I was at the REI in Denver last Saturday just killing time before a parts run, and I got talking to this older dude in the camping aisle. He asked what bag I used, and I said my old synthetic 20 degree bag Ive had for maybe 5 years. He just laughed and said I was probably sleeping cold because the insulation breaks down way faster than people think. He mentioned that after about 50 nights of use, the loft drops by like 30 percent. I never really considered that. So I got home and checked my bag, and sure enough it felt thin as a blanket compared to what I remembered. Now Im trying to decide if I want to drop cash on a new bag or just add a liner or something. Has anyone actually measured their bag's loft over time and noticed the difference?
