1mm neoprene is the most flexible and comfortable combination of neoprene foam and jersey available. The 1mm Neo women’s vest is the perfect amount of added warmth and rashguard protection to extend your warm-water surf session. Flatlock seams offer impressive durability without compromising flexibility. and the seamless paddle zone makes for a rash-free paddling experience. all with the ease of a full-zip front-entry closure. And we use a solvent-free laminate to bond the jersey to the neoprene. which is a safer and healthier alternative for the people building the vest. and for the environment. The endless session is here. thanks to the 1mm Neo flatlock vest.
