Vympel created as new generation of Alpha vest (they are really popular in Special Forces). It's very adjustable vest, that can be transform even in heavy bodyarmor (with back part (not included, you can buy it separated), front one pouch included).
It's include front one pouch for plate. Even if you don't use plate, you can use it as additional space for Molle pouches (it have Molle section too!), or as additional protection in Airsoft and pouch for documents or maps.
With back plate (buy here) you can transfer this vest in heavy Plate Carrier.
