Speedbox is a rugged, stackable, rolling trunk designed to make palletizing military gear fast and easy. Designed around the dimensions of the 463-L pallet, these roto-molded (think Yeti cooler) trunks are shatter-resistant, water-proof, and buoyant. They roll on no-flat tires that are offroad ready and feature a beefy handle for towing around the 300 pound capacity of gear.
The Speedbox is certainly aimed squarely at the military market but it could also be used as a way to store and transport gear for hunting camp, a multi-day carbine class, or whatever else you can think of that might need rugged, water-proof storage.
