HPRC 3500 Backpack Case

Yes, the HPRC 3500 is designed to meet standard airline carry-on size requirements. However, it is always recommended to check with your specific airline before flying, as size restrictions can vary.

TTX01 is a high-performance polypropylene resin that provides an exceptional strength-to-weight ratio. It makes the case virtually crushproof and watertight while keeping it significantly lighter than traditional hard-shell cases.

The case features an ergonomic design with antibacterial foam padding and adjustable straps to distribute weight evenly. While it is more structured than a soft-sided bag, the padding is specifically engineered to provide support during transit.

The automatic pressure relief valve balances the internal air pressure of the case with the outside environment. This prevents the case from becoming vacuum-sealed due to altitude changes, making it easy to open once you land.

Yes, the HPRC 3500 is available with cubed foam that you can pluck to fit your specific gear, an interior nylon bag for flexible storage, or empty if you prefer to use your own dividers.

The case is fully waterproof and holds an IP67 rating. This means it is completely sealed against dust and can withstand immersion in water up to one meter deep for 30 minutes.
