Minimal weight. Maximum speed. The smartest aero upgrade in triathlon. Key Features Ultra-light French ribbed aero fabric disrupts airflow to reduce drag Aerodynamic shaping reduces wake on lower-leg "bluff body" areas Fully heat-welded construction – zero seams, zero compromise High-compression fit supports muscle performance and form retention Wind tunnel and real-world tested for proven drag reduction UPF 50+ sun protection for long-course racing in exposed conditions Swim-legal – wear under your wetsuit to save time in T1 Made with OEKO-TEX® Standard 100 certified fabrics Best value per Watt saved in your triathlon setup – greater drag reduction than most aero wheelsets Designed to pair with the VORTEX Tri-suit and AirEdge Ultra-Light Cap Available in Black with tonal logo – sleek, stealth, uncompromising Product Description The TRI-FIT VORTEX Calf Sleeves were engineered for one purpose: to save watts and increase speed, where it matters most. Made from the same ultra-light woven French ribbed aero fabric as our flagship VORTEX Tri-suit, these sleeves aren’t just an aesthetic upgrade, they’re a high-performance weapon. On areas of the body like the calves, known as "bluff bodies" due to their non-aerodynamic shape, ribbed fabrics help transition airflow from laminar to turbulent, reducing the size of the wake behind the rider and lowering overall drag. This means more speed for less effort. Unlike traditional compression sleeves, VORTEX Calf Sleeves are fully heat-welded for a smooth, seam-free surface, and ribbed for aerodynamic efficiency. The compressive fit helps maintain leg form and muscle performance over long distances without being restrictive, while the UPF 50+ rating protects your skin when racing under the sun. They’re also swim-legal, meaning you can wear them under your wetsuit and save precious seconds in T1. Backed by wind tunnel and real-world testing, and made using OEKO-TEX® certified fabrics, the VORTEX Calf Sleeves are more than a marginal gain, they’re possibly the best value Watt upgrade in all of triathlon. Delivering more aerodynamic benefit than a high-end aero wheelset. Pair them with the VORTEX Tri-suit and AirEdge Running Cap for the ultimate pro-level setup.
