These Snowbee Granite PVC Chest Waders are manufactured from a durable, heavy-duty, hard-wearing, reinforced PVC laminate which is as tough as it gets, but you’ll find the waders are extremely soft, light and flexible, for added comfort. The outer PVC Wader layer is laminated to a tough, woven nylon inner lining, making the material super-strong and almost rip-proof, whilst remaining lightweight. The Snowbee Granite Waders use a unique new seam welding technology which are fused together with an integral tape, using a new Sonic Welding process, leaving the finished seams immensely strong.
