Comments about Other Innova 70-Liter Deluxe Drybag/Backpack, Black:

This backpack can hold my inflatable kayak (Innova Twist), paddle, hand pump, and pfd in the main compartment if I let things stick out on top a little. The small pouch in front holds my cloth diaper (for wiping dry my kayak after), cable lock (in case I want to walk away from my kayak for a while), skegg, and hand sanitizer.
Easy, convenient way to store and carry all my kayak stuff. Not sure how durable it will be, though.
