Belt closure for a SCUBA buoyancy control device (inflatable vest).  The belt will be used to hold the scuba tank to the divers back.  Need something tough yet flexible.  Would like to experiment with different elasticity as well as thicknesses.  It would be great to receive a few samples of the different products that you provide with dimensions about 3 feet in length and 1.5 - 2.0 inches in width. 

Thank you in advance,
