The new lightweight Dry Tech carry bag from Wilson only weighs 4.5lbs/2kgs making it easy to carry around the golf course. Due to its lightweight nature it is also easy to transport to & from the course. The bag is extremely waterproof with the nylon fabric being coated on both sides using a PU (polyurethane) coating. All of the zips on the bag are fully waterproofed with all stitching lines/piping being seam sealed.
