The StrechCordz Quick Connect Kit is an enhancement of the original Quick Connect and allows for different drill sets for in-water resistance training with the use of three different length safety cord tubes (4', 10', and 20'). Each length of tubing serves a particular purpose and with the Quick Connection attachments, it is easy to move from one station to the next. Each StrechCordz Quick Connect Kit features two neoprene-padded waist belts with connection strap, which fits up to a 44in/1.1m waist. Three safety cord tubes ( 4ft/1.22m, 10ft/3m and 20ft/6m) with a Quick Connect buckle on one end and mounting loop on the opposite end. Choose from 4 resistance levels. The Red has 12 - 31 lbs of resistance.
