These are used medic assault packs from Skedco. These backpacks are similar to the issued M9 medic packs used in the US Military and offer the user tons of room. Inside the backpack there are 5 removable pockets and a removable mesh zippered insert with three pockets. The user can arrange and carry what they want, how they want. On the front of the pack is MOLLE webbing for the addition of pouches or other accessories.
This backpack is new and unused but was previously packed full of medical supplies. When the supplies expired they were removed from the bag, so the bag has some light scuffs. There are also some light pen marks on the transparent side of the inserts.
