Introducing the TYR Fusion 2™ Aerofit Shortjohn. Where the swim lab meets the starting block. Engineered for competition at the highest level, the Fusion 2™ Aerofit brings together some of the most advanced aquatic engineering ever developed — combining decades of proven innovation with next-generation construction to deliver measurable speed in the water. Hydrophobic fabric construction repels water at the surface level, while low-profile flatlock stitching minimizes drag across every seam. Fabrication Logic and Fluid Channel Dynamics work in concert to optimize water flow across the body, and calenderized Isolated Compression technology enhances glide efficiency and drives increased speed through every stroke. This is not just a suit — it is the result of what happens when TYR's past and future meet in the same lane.
