The most unique innovation in the T2 is its back
panel, which is made of shock-absorbing body armor for impact protection. On the Aero Pro, this panel can be replaced with a hydration bladder with a tube feed. The
flotation is constructed within a woven shirt with a close-fitting neck and waist gaiter
to eliminate snag points. For Land Rover BAR sailors, the T2 also includes a knife
pocket, accessible to both hands, and a recessed emergency oxygen cylinder in the
back panel, but these features are not included in the Aero Pro.
