Mosquito Cobra The A-TACS Mosquito Cobra is Tactical Concealment's lightest weight and most compactable model offered. It is teh same as the Viper series, with the addition on the longer back drape. It is well suited for extreme environments of extreme heat or constant wetness. It is completely breathable and retains very little moisture when wet. Ghillie garnish and natural foliage can be tied directly onto the nylon 550 cord that is tacked onto the entire exterior surface of the garment in a wide-grid format.
