Technologies

Targeted compression

Anatomical compression on the arch and ankle to reduce muscle vibration and improve proprioception throughout your effort.

Achilles Support

The combined effect of the 3D.Dots and Flat.Dots along the Achilles tendon protect it from friction and pressure whilst optimizing ventilation.

3D Waffle Effect

The "Waffle Effect" weave optimises shock absorption and offers increased protection on the entire leg. It also eliminates any feeling of constriction and increases the massaging effect, thus improving microcirculation.

Description

The R2v2 compression sleeves are perhaps our most iconic product. Seen everywhere from practice sessions to podiums thanks to their unrivalled comfort and support, these scientifically-designed sleeves have revolutionised compression-wear. Whilst it`d be easy for us to rest on our laurels, we`ve only kept innovating, and we`re now proud to present the evolution of the R2v2` the R2 3.0. To build on the classic, we took all the features that made the R2v2 so well-respected: like its exclusive seamless multi-gradual compression, the quick-drying fabric and the purposely designed K-Protect knee tab designed to reduce shock and combined them with even more revolutionary details. The new Fibular Stripes activate proprioception to increase balance and stability, meaning less sprains out on the trail. Whilst targeted horizontal waffle knit areas promote microcirculation and lymphatic flow, reducing shin splints & inflammation. And for when the sun goes down, we added a reflective logo to the back of the sleeve for heightened visibility. After learning of a recent scientific report which showed that compression sleeves can help reduce stomach problems after strenuous activity, we honed these waffle knit zones to further promote blood flow around the body and reduce intestinal damage. In short, no more stomach-cramp-induced DNFs. Whether you`re jogging around the park or you`re halfway through the Barkley Marathons, the R2 3.0 will support you in going the extra mile.

FAQ

Everything about R2 3.0

What are the R2 3.0 designed for?

The R2 3.0 are designed for trail running, using targeted calf compression and support during effort. Its design focuses on stability and proprioception, together with targeted compression. That makes it relevant to athletes looking for a product matched to the practical demands of trail running.

How do these calf sleeves support stability and control?

One of the main features is improved balance and stability through textured fibular stripes which stimulate proprioceptors, increasing grip and reducing the chance of sprained ankles. In practice, this is intended to help maintain control when terrain or fatigue makes movement less stable. This works alongside targeted compression so the design addresses more than one demand of trail running.

How do these calf sleeves use compression to support performance?

One of the main features is high-level muscle support to the calves, decreasing the risk of injury and cramps through targeted 360-degree compression. In practice, this is intended to support the working muscles and limit unnecessary movement during effort. This works alongside targeted compression so the design addresses more than one demand of trail running.

How do these calf sleeves manage heat, sweat and moisture?

One of the main features is targeted waffle knit zones promote microcirculation, reducing inflammation as well as stomach problems over long distance runs. In practice, this is intended to keep the product more comfortable when sweat and temperature increase. This works alongside stability and proprioception so the design addresses more than one demand of trail running.

What are the R2 3.0 made from, and how much do they weigh?

The listed composition is MAIN FABRIC: 65% Polyamide 35% Elastane. The listed net weight is 34 g. These specifications are useful when comparing materials and overall weight with other calf sleeves for trail running.
