Down River Cup Holder
Works great with insulated tumblers, nalgen bottles, and cans with a good sized cozie. Ended up buying enough for every corner of the raft!
Perfect for holding water bottles
I always have a Nalgene water bottle, and this is perfect for holding those in our raft (though it's great for smaller diameter water bottles too.) We have one by the captain's chair and another for up front. No more loose, rolling around-on-the-bottom of the raft water bottles! It's not flip-proof, but it's super convenient.
