GREAT BAG!! Try one today?Sealine Baja bags are a thicker, heavier fabric than other some of their product lines (compare MM thickness & weights if you want heavier/lighter materials) they are very rugged, I have used them for years. you can use without regard of damaging them, you do not need to baby them or be gentle. can be stored rolled up for years at a time. can stay wet/in water for days at a time. can be set/drug on rough terrain when using so no footprint tarp is needed.
