August in Chamonix can be hot, and it can be freezing. So turning up to the UTMB® with your layering game on point is absolutely essential. The UTMB® edition of the ArmForce Ultralight sleeves gives you a flexible pull-on, pull-off solution that makes life easier when all you want to think about is running. Designed from the same fabric as our high-performance socks, the seamless sleeves are extremely comfortable and lightweight. Thermoregulation is key, perfect to wear under a t-shirt at the start of the race and through the first nightly hours. Gentle compressive properties precisely target key muscles for stimulated blood flow and support, so your arms stay fresh as the hours wear on. Particular attention is given to the elbow area, where a lighter weave allows for exceptional freedom of movement and extra ventilation. Finally, signature 3D.Dots are built into the forearms for enhanced blood circulation, although they may also double-up as excellent sweatbands as you grind up towards Col Ferret. Super flexible, pull them off when you get hot and stuff them in a pocket, ready to pull on again when the air freshens. The licenced 2021 UTMB® design features the official event logos and a checkered blue pattern on the forearms. Highly versatile and an absolute must-have in your essential gear.
