Summer: PLCE with 2 magazine and 1 utility pouch (for water), as its light does, not rest on my huge stomach and allows the rest of my body to "breathe"
Winter: Viper assault vest as its adds some insulation and carries all my mags and bottle of water for the winter play
KISS is my motto. (and cheap as its a game after all and no amount of money is every going to improve my performance, apart from a personal trainer!)
