The ION Element 5/4 Back Zip wetsuit for men caters to the needs of water men who don’t need much to enjoy being in the ocean. Supple, stretchy and robust; the Element line includes many features from the more technical end of the range: Silk_Stuff inside lining on the upper body provides a comfortable fit and good stretch in the shoulder area. Hot_Stuff 2.0 – ION’s stretchiest thermo lining – improves warmth, flexibility, and comfort even further. On top, critical seams were reinforced to make this an everlasting basic on many trips. Element wetsuits with back zip are equipped with a thin protective padding at the shins.
