The first time I went sea kayak camping carrying my gear in armfuls from kayak to campsite was a job of five trips!
Then on the next trip I wised up and used my netting duck decoy bag and did it all in one trip.
My decoy bag has nylon webbing shoulder straps and, for a short haul from boat to campsite, this is the way to go. Plus it is light, stows small, is made of strong nylon mesh and dries fast. Best of all, being a duck hunter, I already had it on hand.
