Peak Climax Pro Zipperless 4/3mm Steamer Wetsuit is a great value for money zipperless steamer with a 100% sealed front zip. It features Peak's flexible and lightweight X-Stretch neoprene for ease of movement in the water. This suit will offer you superior warmth and stretch due to its zipperless entry and its glued and blind-stitched (GBS) seams. A zipperless wetsuit maximises the neoprenes stretch as it is not comprimised by a zip. It also eliminates the flushing that is created by wetsuits with a back zip. When it comes to reliability and trust, you can comfortably put this wetsuit to the test knowing that it has been designed and created by Ripcurl, renowned for their durable and well-crafted wetsuits. Peak Climax Pro Zipperless 4/3mm Steamer Wetsuit Features: 4/3mm Variable Thickness: By laying 3mm Neoprene in the 'paddle zones' and 4mm in the non-stretch zones the warmth/stretch relationship is optimised. The warmer your abdomen the less work your body is doing to retain warmth. Zipperless Entry - a market-leading enclosure for stretch and warmth, giving the ultimate seal against water and maximising the suit's stretch - learn more GBS seams with internal tape: A blind-stitch is used to avoid creating pin-holes in which water can enter the suit, this is done by using a hooked needle that penetrates around 40-60% of the material depth. The non-stitched portion is then sealed with an elastic glue that not only greatly improves durability but creates an additional level of seal. Watch our video on wetsuit seams.
