Thunderhead Waterproof Backpack 28L - Fully Submersible Protection

Our review of the Thunderhead Waterproof Backpack finds it best suited for anglers and outdoorspeople who need guaranteed dry storage without sacrificing comfort. Built around a fully submersible TRU Zip zipper and bombproof 906D TPU coated NewStream fabric, the pack's single biggest advantage is its waterproof reliability: cameras, lunch, and tackle stayed dry in wet, rough conditions during extended use. The harness and lightweight foam straps make it wearable all day while the daisy chain and four-way attachments let anglers organize gear for quick access.

Key Features

• Fully submersible closure: The TRU Zip zipper on the main pocket provides proven waterproof protection to keep electronics and tackle dry even if briefly submerged.
• Durable fabric: 906D TPU coated NewStream fabric gives abrasion resistance and long-term weather protection in rocky or brushy environments.
• Comfortable carry: Lightweight foam shoulder strap, hip belt, and molded back panel reduce fatigue over long hikes or full days on the water.
• Accessory-ready: Coated webbing daisy chain, d-ring, and four-way back panel attachments accept chest packs, pouches, or other fishing accessories for organized setups.
• System compatibility: Designed to connect with Fishpond chest packs and vests for modular use when fishing from shore or wading.
• Roomy capacity: 28L interior carries a day's worth of gear including tackle, clothing, and camera equipment while remaining packable at 3.05 lbs.

Who It's For

The Thunderhead is ideal for committed fly fishermen, guides, and day hikers who need a reliable waterproof pack that can endure river runs, boat decks, and brushy trails. The waterproof zipper and heavy TPU coating make it a sensible choice for anyone carrying electronics or camera gear into wet environments.

It is less appropriate for ultralight backpackers who prioritize minimal weight over absolute waterproofing, or for those who need heavy internal organization for non-fishing uses; the pack emphasizes protection and ruggedness over many small internal compartments.
