I recently saw a pic of someone using a mil poncho liner as an underquilt. I was wondering what the expected temp rating for this would be, weight, bulk of liner etc.
Has anyone used this successfully as a late spring early fall substitute for either pad or JRB? My concern is that I already have a pad setup with SPE that works well, but is a pain in the rear compared to an underquilt solution. I am looking for a lightweight alternative to warmer weather hanging where the JRB might be too much. Generally I am very comfy down to the 30's with just a pad/SPE combo so while warmth is a concern, i am more inclined to a lightweight/compact replacement.
Cheers, thanks
