Our new 3/8” LEASHLOK HAWAII Attachments are made with a Polyester webbing that has a 3800 lbs. breaking strength. Polyester webbing is superior to the old Polypropylene webbing and stretches less, is more resistant to rot and mildew, has a higher strength rating and a softer feel in your hands. Our new webbing is made from a proprietary formula and is not affected by most chemicals, sunlight, oil, salt, water, fungus or moisture and the color and logo are actually a thermal dye technology which is very durable in all conditions.
