These updated arm warmers are perfect for cool and wet weather. Crafted from a warmer textile with water - repellency, they're versatile for layering in fall, winter, and spring. Ideal for early spring, late fall, or mild winter days, the R Winter Arm Warmers P1 offer great breathability and thermoregulation, ensuring total comfort in cool, wet, and windy conditions. The upgraded textile keeps you warm even when wet, and when it gets warmer and the road dries, they can be easily packed into a jersey pocket. For added flexibility, their low - volume, second - skin fit layers smoothly under wind and rain shells, adding insulation to your storm - proof gear. The RX Extreme textile, from the RX family, is a top - notch insulator. It's a brushed, thermoregulating warp - knit fabric with high breathability and a water - repellent treatment, perfect for racing in cool, rainy, and windy conditions. Our AEPD 11 racingFit, based on WorldTour feedback, offers a second - skin, aerodynamic fit with 360 - degree compression and stability. The Acqua Shield Tec is an eco - friendly water - repellent treatment that makes water bead up and roll off, keeping you dry. The PILtec Plug - In is a lightweight, ultrabreathable band at the arm opening with a microdot silicone treatment to keep the warmers and jersey in place, even when wet. The raw - cut cuffs lie flat and are low - volume, reducing friction and bulky hems when layered with jerseys, jackets, and gloves. Materials: 76% PA 24% EA.

How to use: Simply slide the arm warmers onto your arms. They're designed to fit snugly, so you'll feel the 360 - degree compression right away. You can wear them on their own during milder cool days or layer them under your wind and rain shells for extra warmth in harsher weather. When it gets warmer, just take them off and pack them in your jersey pocket. Note: These arm warmers are made for cool and wet conditions. Don't expect them to be as effective in extremely hot weather. Also, while they're water - repellent, they're not completely waterproof, so avoid long - term exposure to heavy rain. Maintenance: After each use, rinse them with cool water and let them air dry. Avoid using harsh detergents as they might damage the water - repellent treatment and the fabric. Store them in a cool, dry place when not in use.
