HEX has collaborated with SUPRA Footwear to create a durable iPhone 4/4S case. The case, available in black or white, is outfitted with SUPRATUF, the same proprietary material used to protect SUPRA branded shoes from liquids and water. SUPRATUF is a high abrasion resistance technology which has been tested with the Taber Abrasion Meter. The Taber measures abrasion in cycles. Regular suede breaks down after only 25-40 cycles. Suede treated with SUPRATUF can withstand more than 200 cycles before abrading.
