Peli 1300 Case with foam black (waterproof, dustproof, crushproof). The 1300 has an open cell core with a solid wall design which makes it super strong - almost crushproof - but also lightweight. The automatic pressure equalisation valve keeps the interior pressure balanced but keeps water out. Combine this with the O-ring seal and you have a fully watertight case. Rated IP67, it has been tested in 1 metre of water for 30 minutes.
