Flexibility for light speed. For speed in the water and the transition out of it, the Proton range uses light, flexible, hydrophobic materials, suitable for strong swimmers looking for an extra edge on their performance. The Fastskin Proton Wetsuit has been developed with Y38 (Yamamoto 38 cell neoprene rubber) - a well balanced foam providing high buoyancy and flexibility that makes it the most versatile neoprene available - to make sure it performs when it counts. Maximotion+ technology in the single piece chest and shoulder panel means your stroke is as unrestricted as possible.

Nice wetsuit if you ...
Nice wetsuit if you ignore the sizing guide. This is my third swimming wetsuit and IÂ’ve hired a fair few over the years. My wife bought Ladies XL and I bought MenÂ’s XL. Hers is larger than mine. She is very pleased with hers but mine is useless for me. This is not what I expected from this company..The fit. I chose MenÂ’s XL as I was in (but at the minimum end of) the height and chest ranges, according to the sizing guide. It doesnÂ’t fit. It is too short in the body too tight around the chest and shoulders so I canÂ’t use it. I tried it on when it was delivered and I expected it to be a snug fit. Unfortunately, I only really found out after using it that it doesnÂ’t allow me to swim freestyle properly and breath to my normal exercising requirement. I bought it to extend my open water swimming season and specifically for an10km swim with some channel swim friends who are training for their solo attempts. Having used it now I canÂ’t return it.
