Speedo Fastskin Proton Wetsuit

Yamamoto 39 Cell Neoprene Rubber
The main body of the suit is formed from Y39 rubber which offers the most buoyancy out of any other rubber currently in existence on the market. This helps to minimise the form of drag created by the immersed body.

Yamamoto 38 Cell Neoprene Rubber
Additionally, Y38 is used throughout the suit, which is a great all-rounder used across many of Speedo’s entry level suits for triathletes. This ensures great levels of flexibility, buoyancy and durability.

Maximotion+
Used in key areas across the suit, the Maximotion+ sections are 1.5mm neoprene panels which create supreme flexibility where you need it most.

Thicker Neoprene Panels
Meanwhile, in other specific areas thicker Neoprene sections are used which provides thermal insulation and further buoyancy.

Fuse Neck
The suit’s fused neck design perfects the comfort of the fit with a watertight neck.

Rear Zipper
The rear zipper makes it easier to take the suit on and off in a hurry.
