It's actually quite amazing to find a surplus backpack at this price, and a vintage one too! A copy of the French Mle. 55 pack, this newer Belgian version is made of rubberized material instead of cotton, reducing the vintage charm but increasing its utilitarian potential by being quite waterproof.
With the approximate volume of a shopping bag and provisions to sort your shit too to some extent, this should do pretty well as your daysack or a retro outdoor pack. Inside dimensions 32 x 37 x 12 cm about. The flap covers the whole mouth and has an M-1910 wire hanger attachment, mainly meant for an e-tool. Rough canvas shoulder straps with metal clips on the bottom and other ones for mag pouch attachment.
Belgian army surplus. Some of these have seen fairly heavy use, some not so much. There can be some stains, dirt, wrinkles, scratches, and surface rust on the metal bits or some fraying on the straps/seams. However, they are still in usable condition. This time these don't have a strong warehouse smell, unlike the cotton packs! However, a little swipe with a rag wouldn't hurt.
