The E-Bomb 4/3 Chest Zip Steamer is built for cold-water sessions that demand warmth without sacrificing stretch. Its 4/3mm thickness provides insulation, while high-stretch E-Bomb neoprene supports performance fit for serious surfing. A chest-zip entry helps create a secure seal, and critical stress-point taping is designed for durability. Warm, flexible, and ready for longer cold-water sessions.
