The Dawn Patrol Chest zip offers performance and durability at a great value. We use E5 neoprene in action panels, and the new Thermoflex neoprene in the body except around the kidneys, where flash lining and mesh protect from the wind.   FEATURES: E5 NEOPRENE - Rip Curl's premium high stretch neoprene. Super stretch and lightweight with a high quality hand feel that is smooth and comfortable against the skin. GLUED & BLIND STITCHED SEAMS -Triple glued, double stitched seam that only penetrates one side of the material providing a high stretch, high strength, water sealed seam. FLASH LINING - Two engineered layers that funnel water rapidly out of the suit once it is hung up. Also one of the warmest and most comfortable linings available. STITCHLESS UNDERARMS -Seamless and stitchless underarm and shoulder panels maximise movement and provide ultimate flexibility. MESH SKIN -Smooth mesh panels that absorb solar heat and reduce wind chill. MAGNETIC STASH POCKET BATWING SYSTEM -Provides barrier between back-zip and body to minimize leakage and flushing (back zip wetsuits only). Stress Point taped - 3/4 E5 TAPED - For increased strength and durability. S-FLEX KNEE -Highly flexible kneepads allowing maximum movement and lasting durability.
