This is a 23-24 Nidecker Supermatic binding. Size is L. I used it about 4-5 times (2-3 hours each time) after purchasing it last season, and I think the product is in good condition. I'm selling it because I bought different bindings and no longer have a chance to use these. There is some minor dirt, but please understand that this is a used item. No claims and no returns accepted. Size: L
