The Adaptive Flotation Cummerbund was built around the Tactical Flotation Support System (TFSS). It is designed to provide 45lbs of positive flotation in seawater at a depth of 33 ft., 57lbs of positive flotation at a depth of 15 ft., and 80lbs of flotation on the surface which is the same amount of lift as the standard TFSS. The flotation is deployed by pulling in a down and outward direction, which initiates the CO2 and inflates the bladders.
The cummerbund also allows you to quickly swap between land and maritime cummerbunds without the hassle of hook and loop. In order to attach this cummerbund, you must use the Attachment Panel, or the Instant Adjust Back Panel to give you a place to connect the Tubes. This cummerbund allows you to adjust your back insert for where you want your Tubes placed and how tight you want your carrier only one time, rather than having to re-adjust when switching between land and maritime. Now you can switch from land to flotation cummerbunds as fast as you can release a Tube! Cummerbunds are sized and available for all current ballistic soft armor inserts. The optional attachment panel is for the rear of the carrier only. This cummerbund is only designed to work with FirstSpear carriers with Tubes on the front.
