Classic meets new school: The Serene achieves the perfect balance between warmth and flexibility. The modern suit was designed for maximum versatility: the focus on arms and legs - where freedom of movement is most important - is on optimal flexibility. On the body, the focus is on perfect thermal insulation. The Serene combines the most intelligent construction techniques with the latest materials. By using Sheico Limestone neoprene and an innovative combination of insulating materials, flexibility has been increased by about 15% compared to previous models. Effective thermal insulation is ensured by an Apex Mesh outer lamination, welded GBS seams, and Hotcell 3GN insulation from the shoulders to the knees. The Serene 5/4 Fullsuit GBS Back Zip is equipped with our E3-Entry-System, which allows for easy entry and a comfortable fit.
