The combo of 4mm neoprene in the chest and 5mm in the core, hips, and lower torso produces a high-float, low-drag sensation that feels fast. This suit will let you swim with a natural kick while making sighting and rotation a breeze. Its shoulders favor a wide, high stroke, though it does take some breaking in to increase flexibility. Once worn in, it’ll keep you warm in pretty frigid water and has a lot of life to give. Just be sure to lube up on the wrists to avoid T1 frustration.
