i'm a member of a local rescue unit HCRU (Huntsville Cave Rescue Unit) and we do also do land searches. I have a bag that is strictly for search and rescue that's always packed and in my car. i have a SLD topquilt and bottom quilt that's synthetic that is not packed and stored uncompressed. My question is if i stuff it in my backpack that stays in the car (because you never know when a callout will come) how long does it take the synthetic fibers to get destroyed and not keep me warm if we have to stay overnight?

thanks
