Compressport Ironman 2026 Limited Edition R2 Oxygen Compression Calf Sleeves

The lightest compression calf sleeve on the market, offering minimum weight and maximum support for the most extreme conditions.

Improved performance through reduced muscle vibration, helping you maintain speed and intensity for longer during effort

High-level muscle support to the calves, decreasing the risk of injury and cramps through targeted 360-degree compression

360° aeration with fast-drying mesh panels, helping keep your calves dry and cool in the hottest conditions

From the lava fields of Kona to the scorched sand of the Sahara—some races require nothing short of the ultimate in performance equipment. Luckily, we created the R2 Oxygen compression sleeve. Developed as an ultra-lightweight version of our iconic R2v2 compression sleeve, made with long distances and extreme conditions in mind, this isn’t just the lightest calf sleeve we make… it’s the lightest calf sleeve on the market, weighing in at a mere 15g. Fast-drying mesh panels provide 360° aeration, whilst that ultra-soft lightweight yarn gives a second-skin feel, so you’ll hardly know you’re wearing them. But that doesn’t mean we’ve skimped on comfort, support and everything else that makes our R2 sleeve so popular. The ultra-thin fibres are proven to retain all compression properties, offering optimum calf support, whilst limiting muscle vibration and damage. For added comfort when you need it the most, those ventilation stripes on the rear of the sleeve are gradually spaced to expand with your muscles as they swell during prolonged efforts, and for those who run after dark, we also added a reflective logo to the back of the sleeve. When the heat is on and the clock is ticking, you’ll be glad you’re wearing the featherlight R2 Oxygen sleeve. After all, if it’s good enough for Fred Van Lierde…
