From deep mountain canyons to saltwater flats, the Thunderhead Lumbar is built for your next big adventure. The Thunderhead Small Submersible Lumbar, like its big brother, is the ultimate waterproof hip pack for anglers who brave extreme conditions in the pursuit of adventure.

Featuring a TRU Zip submersible zipper, the Thunderhead Small Lumbar delivers an airtight closure system to ensure everything stays completely dry.

This makes your setup incredibly versatile and modular, giving you the freedom to customize your gear setup for any fishing scenario. Crafted with our ultra-tough 900D TPU-coated NewStream fabric, the Thunderhead Small Lumbar can withstand even the harshest environments. From the relentless humidity of the Bahamas to the wind-swept tundras of Southern Patagonia, the Thunderhead Small Lumbar is the perfect lumbar pack for any environment you may encounter.
