The Merlin is another great example of Maxpedition's innovation. Starting off looking like an innocent GP pouch, the main compartment expands out to transform the pouch into a full backpack.
When all packed up the "front" has loop velcro for ID patches, a shockcord rig, and a sleeve loop for belt mounting. Double zippers open up a pouch with elastic loops inside. Moving to the opposite side is a similar sized pouch, but with PALS compatible webbing for using malice clips. Dual zippers open up clamshell style and the inside has interesting divider panel that makes the pouch separated for left and right access. The snap can be used as zipper divider for this setup or a zipper lock. Once the middle is expanded, both of the end pouches are easily accessible on the outside of the backpack. Athough the exterior is made of 1000d ballistic nylon, the backpack material is 420d so it can be packed up. The backpack has an extra hydration pocket with velcro opening and D-ring which can hold up to a 100oz bladder. Currently available in Black, Green, Khaki, and ACU.
