So I am looking to buy a caving backpack, not spend then bank on it I might add. doing the basic crawling in the mudd tight holes maybe a little water involved. No climbing robes or what have you to start. Can anyone reccomend a good bag that will keep all my extra gear dry but be comfortable to lug around. I have a NorthFace Terra 45 for hiking and what not, but i think that would be a bit bulky to take into a cave. Any help is appreccitated.
