Know before you buy
The Thunderhead is fully submersible. It features a waterproof TRU Zip closure and 900D TPU coated fabric, meaning it can handle being fully submerged in water without letting moisture reach your gear.
The 28L capacity is ideal for a full day on the water or a long hike. It comfortably fits a camera, a rain shell, a lunch, and a decent amount of tackle boxes or fly boxes, though it is not designed for multi-day camping trips.
The main compartment is a large, open space to maximize versatility, but it does include a removable interior pocket. This helps keep smaller essentials like keys, licenses, or tippet spools from getting lost at the bottom of the bag.
Yes, it is designed with a molded back panel and lightweight foam straps to distribute weight evenly. While it lacks a rigid internal frame, the harness system is supportive enough for standard hiking and wading distances.
Absolutely. The pack features multiple external attachment points and dedicated Hypalon tabs specifically designed for securing items like radios, GPS units, or external tool retractors.
