The EVA Sleeve Covers features two shapes to choose from. A straight cylindrical shape with a subtle bevel at the top or a slight trumpeted shape like the classic nubbin style. Each shape has its specific size designed to fit TCH hidden thread cover reel seats in both size 13 and size 15. Crafted from high-durometer EVA, these sleeves offer a slim profile and maintain a firm, responsive feel, providing consistent feedback and lasting comfort during extended days on the water.
