Roots in Aviation

Thumbs up.

I love mine, so versatile, Innovative and well built. Can’t wait to give my last order for Christmas presents to all those Envious fishing - family and close friends of mine who joined me in my raft on the rivers this year.

Not a drop spilled!

I used the bar mount and can cooler for the first time on my raft with glowing results. Not a drop of fermented beverage spilled, even when I ran some light rapids! Easy to install, easy to lock in, keeps the can upright, keeps the can cold. A must for any river outfit.
