Keep optics, electronics or other sensitive equipment protected in a used U.S. Military Surplus Zero Waterproof Case. Each is constructed of waterproof/windproof plastic and is fully foam lined. It's a sizable 42" x 19" x 27", but easy to carry thanks to the 4 loop handles with foam grips. If you've got "expensive, sensitive stuff", go ahead and buy more than one. They're stackable. The durability and versatility of these Cases will leave you with plenty of storage and transport options.
