For sale or trade are US Mil Spec Night Vision Hard Cases. I have 10 of these. These would make excellent custom panniers. They are super tough. The military purchased these for storing night vision goggles. These are airtight, waterproof, high-impact plastic cases that make Pelican cases look like they come from Toys R Us. Just being near these will make chest hair grow spontaneously. These have a pressure relief valve on the front next to the spring retracting handle. These cases are 7X13.5X14in interior, and 8X16X15in exterior and weigh 7 lbs each. They have nubs and ribs that interlock to allow multiple cases to be stacked securely. The foam lining the case is moulded for night vision goggles, but those are easily modified or removed. Replacement foam sets are available aftermarket in a myriad of configurations, or talk to me and I'll give you instructions on how to custom mould these for your whatever you end up putting in here. The foam inserts pull right out if you're just looking for the hard case. $50 each, I will have to figure out shipping. We can talk bulk discount for 3 or more, and I am intereted in trades for pretty much anything. Let me know what you have and we can work something out.
