i roll the inflating one into tube but i'd rather just bung one on outside plus it can be used as a sit mat without bivi bag too
Lol, I've been chucking one in the canoe lately but always for get it's there until I go home again.
I've got a Thermarest Ridge rest going spare if you're interested.
A few years old but no snags or rips.
