Durabag Kayak - Product Reviews
My only improvement suggestion, please provide a removal cap for the mouth valve as you do for some other source products. Kayak gear is often transported in a box / bucket in the back of a car, and it's hard to keep the mouth piece clean and out of contact with other gear without a cap. I fitted a cap from another Source product I own and it's much better than without one.
Overall I highly recommend this bag for kayakers and surf ski riders.
