The Black Widow Water Crossing Bra is made from 100% military spec waterproof nylon. As with any water crossing bra, the chance of piercing the bra whilst crossing a stream is likely. The Black Widow water bra, using this latest material, may pierce, but will not run or fray. The Water Bra will also fold into its own incorporated carry bag and, when set up, the bag is automatically reversed and is on the front of the car to house recovery gear if required. The car bra is fitted with stainless steel eyelets (including one in the base of the bag), 6mm bungee cord and 3 drain ports in the base to avoid water bellying. RRP is $139.00.
