In the second edition of Radar's "never flat" X-vest, foam has been re-segmented for a more athletic form. The secret is in the 5-panel design which adds specific side panels for rib protection and more even foam distribution. Cylindrical construction and asymmetrical segmentation fills more voids than ever before. Two-way stretch neoprene with Glideskin and water-resistant liner keep the vest lightweight and comfortable. Features a deep V-neckline, oversized armholes, tailored bottom design for anatomical fit, and a 2 buckle/front zip closure. Vest will fit longer torsos. USCG approved. Chest sizes: S(31"-34"), M(34"-37"), L(37"-40"), XL(40"-43"), 2XL(43"-46").
