Eleven 10 E10-7021-NVY: The Eleven 10 Rigid TQ Case Jacket v2 for C-A-T is an optional accessory that when installed, completely covers your tourniquet to protect it from the elements. It also helps provide a clean, uniform look. The Jacket integrates with the existing hardware on your RIGID\'s rear mounting face, and the included snap uses an existing hole on the front of the Cross Front Rigid models. When deployed, the Jacket \'\'breaks away\'\' so there is no snagging on your tourniquet. The updated version of the Jacket is made with Blue Force Gear\'s ULTRAcomp material. ULTRAcomp combines the properties of a rubber based laminate - resistance to tear, abrasion, water, bacteria and fungus - and added a Cordura fabric facing for color or pattern and reduced IR signature.
