ScaleTech is a revolutionary, patent-pending technology that blends modern materials with ancient concepts. Until now, every snake-proof chap and gaiter that uses inserts has an inherent flaw; when the inserts are laid side by side a small gap is created between the panels and this area is NOT snake-proof--regardless of the competitors claims. Rattlers Brand ScaleTech Chaps and Gaiters feature ScaleTech, where we have overlapped the inserts to create layers and as a result...eliminated the gap.
