New Pro Mesh is used for the protective outer layer on the Flexible Filly Splint Boots. Pro Mesh material acts like ‘flexible horse armor’ offering the ultimate combination of breathability with impact and abrasion protection as well as support and durability.  It uses a honeycomb hex pattern that reduces weight plus offers an optimum mix of protection, air flow, strength, and flexibility. Designed to keep out grit and sand it helps guard against rubbing.
