Large mountaineering backpack made from hi-tech materials. Thanks to reflex pads, it is visible even in fog or dark.
It is used as an external and separate means of storing items from the player’s main inventory and therefore makes the player able to carry more items.
Since the Mountain Backpack is as big as the upper body of the player and is only available in bright colours, it can make you stand out to other players. It also makes you unable to look over your shoulders in first person mode, a hindrance if you need to look around while running. For these reasons many players find the Hunting Backpack more preferable as it has a camouflaged model, at the loss of only 5 storage slots. If a player has access to any of the 4 colors of Mountain Backpacks, the green Mountain Backpack is preferable because offers the best camouflage in woodland areas.
Currently, there is a glitch which allows you to carry one of these inside another. This effectively gives you 10 extra slots per bag since it occupies only 25. The bounds of this glitch are currently not known.
