The cycling arm warmers are an item of the cycle gear that covers the arms, from the wrist to the biceps, guaranteeing an adequate temperature or waterproofing, in those moments when a jacket is too much. Their tight, elastic fit provides compression that translates into comfort. They're used in nearly all the cycle modes and also in the world of running.
When you know it's going to be hot once the sun's up, but it's still too cool in the early hours of the morning to go with just the short sleeves of the jersey, arm warmers are the perfect item.
Arm warmers are one of the most practical garments of the cycling gear, together with the leg warmers, that exercise the same function on the legs.
One of the most appreciated details for the maximum comfort of the arm warmers is the silicone trim inside the sleeve to avoid slippage due to sweat or rubbing against other garments. In spite of the different sizes, arm volume is not always the same, and therefore the silicone trim improves the hold on the arm.
Just like the cycling jackets, you can find them lined inside, waterproof or of thinner fabric that allows better ventilation for those moments of less cold. The great variety of fabrics and technology allows us to choose between different types of arm warmers according to the weather conditions that you find wherever your bicycle takes you.
During the mid-seasons, it's normal to cycle with a vest and arm warmers over the jersey during the first and last hours of the day. Also, their small volume make them easy and convenient to store, whether in the pockets of the jersey and jacket or inside the back pack occupying very little space.
