The artifact count can be increased to 4 (2 without the Calibration Kit) and the weight can be cut almost by half, but it has no carry weight upgrade and the bulletproof protection cannot be increased without a Callibration Kit. It combines traditional(anomaly and damage) with 'utility'(health, stamina and bleeding regeneration) upgrades. Uniquely for a suit with no integrated helmet, it has a psy-resistance upgrade.
The CS-3a suit is a balanced suit, sitting a bit under the PSZ-9d Duty Armor and Guardian of Freedom suit both in protection and upgrades. Novikov, the scientists' technician and a former Clear Sky member, recognizes it immediately as his own handiwork. The suit can only be obtained from Nimble when asking for a body armor at a hefty price of 40000 RU (but it does come with a tactical helmet). Heavier, kevlar-padded panels are added to the arms and legs to increase the protective performance.
The CS-3a consists of a tactical vest (with medium grade military kevlar) with carrying pouches, carried over a sky blue/white camouflage shirt and dark pants with metal kneepads and hiking boots.
