The O'Neill Sector 5mm Wetsuit is one of the best women's wetsuits out there, period. It uses the best technologies in wetsuit design. O'Neill has been making wetsuits for over 40 years and they really know their stuff.
O'Neill are one of the few wetsuit manufacturers who cut their ladies sizes to a swimwear fit, allowing for a more comfortable fit and greater mobility.
The UltraFlex neoprene means this suit is very easy to get on and off as well as very comfortable. The firewall insulation and Fluid Seam weld make it incredibly warm without sacrificing the mobility that make O'Neill suits great in the first place.
