Genuine G.I. 3 Piece 1 Quart Plastic Canteens are BPA Free and made of a high-density polyethylene and will fit into any G.I Style canteen cover. The military canteens are made in the USA. NSN# 8465-00-889-3744 / MIL SPEC: MIL-C-43103.
Canteen is a 10 as far as I'm concerned: USA made desert color, good durable (non-issued) materials.
Pouches are made in China, though.
