Description

Many of our pro trailers opt for compression sleeves during ultra trails, as it means they can quickly change socks at the checkpoints without losing time or energy. So if you're heading to Chamonix this August, the licenced UTMB® edition of our R2 Oxygen calf sleeves might be exactly what you're looking for. These top-of-the-range sleeves are ultralight and developed specifically for strong racing in the most gruelling trail events. Weighing in at a mere 11g, the sleeves offer an ultra-soft, second-skin feel which you will appreciate as the night wears on and the path heads up. They may be extra-thin, but the swiss-woven fibres provide elite-level, medically-controlled support and compression to support you all the way to the finish line. Muscle vibration and damage are limited while blood flow is increased so you can run faster, for longer. With strategically-placed, quick-drying mesh panels for maximum 360° aeration, your legs will not feel quite so heavy as you run over Col des Montets and start the final descent. Easy to pull on thanks to optimised horizontal and vertical stretch, we guarantee you will feel no chafing or discomfort. This licenced UTMB® edition comes in a classy checkered blue pattern with the official event logos. Now "all" you need to do is pack your essential gear, take a deep breath and trust your legs and yourself.

Everything about R2 Oxygen

What are the R2 Oxygen designed for?

The R2 Oxygen are designed for trail running, using targeted calf compression and support during effort. Its design focuses on targeted compression, 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 use compression to support performance?

One of the main features is postponed fatigue and improved performance through reduced muscle vibration, helping you maintain speed and intensity for longer during effort. 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 support stability and control?

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 help maintain control when terrain or fatigue makes movement less stable. This works alongside thermoregulation and moisture management 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 maximum thermoregulation thanks to mesh ventilation panels woven directly into the fabric, helping keep your calfs dry and cool in the hottest conditions. In practice, this is intended to keep the product more comfortable when sweat and temperature increase. This works alongside targeted compression so the design addresses more than one demand of trail running.

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

The listed composition is 78% Polyamide, 22% Elastane. The listed net weight is 28 g. That specification fits the product’s emphasis on reducing bulk during trail running. For trail running, that matters most when small comfort or equipment issues can become more noticeable as the effort gets longer.
