From deep mountain canyons to saltwater flats, the thunderhead lumbar is built for your next big adventure. 
The Thunderhead Lumbar is a fully waterproof pack built with your comfort and personal gear in mind, even when you are in the worst conditions. If you don’t like the weather, wait 10 minutes. We designed this bag for anglers who brave conditions in search of the moment it all goes off. The clean layout gives you a simple way to organize your gear, ranging from high-end cameras, and boxes of hand-tied flies, to your peanut butter and jelly, all of which need to stay dry. Not only does it deliver an airtight closure system with the TRU Zip waterproof and submersible zipper, but it is also built for all-day comfort with padding in all the right places. Constructed out of our ultra tough 900D TPU coated NewStream fabric*, our Thunderhead is as tough as the name suggests. From deep mountain canyons to saltwater flats, the Thunderhead Lumbar is built for your next big adventure.
