A lot of items on their web site are out of stock. I purchased the Alps Grand Slam vest and am happy with it. After two years I lost a leg clamp and screw and called the company and asked to purchase two clamps and screws and I was pleasantly surprised that I would receive in the mail the two clamps and screws for free with free shipping. I'm satisfied and recommend the Alps product line. Unfortunately I can't help you but if you call the number on their sight I'm sure someone could help you.
