MISSION WORKSHOP R2 Arkiv Field Pack 20L There are two types of Arkiv Field Packs. The R6 has two rails on the front and two on each side, while this R2 has a simpler structure with only rails on the front, but I think it has more pockets than other backpacks. (Of course, you can add more later.) The R6 is too cluttered, so I've been using this one. This is a modified version with an AUSTRIALPIN Cobra buckle from Australia, done at a specialty shop (the parts and order cost more than 1/3 of the listing price, and the original plastic buckle is included). It has an optional large front pocket and an optional accessory on the shoulder, which is large enough to be used as a wallet. There is some fading and wear from use, but there are no scratches or tears, and it is generally clean. There is no functional damage, but the waist belt is not included. This item cost a considerable amount in total, and I could have listed the items separately, but I decided to list them together. The ruggedness of the Cobra buckle makes for a cool backpack. It might be good for military enthusiasts as well. For those who understand used items, I think this product is not often seen, so please consider it.
