Sports Arm Sleeves, Set of 2 – Lightweight, Breathable Arm Warmers with Reflectors, Elastic, Unisex

Start at 12 degrees, arrive at 22

It’s too warm for a jacket, but too chilly on your arms without a layer—and that changes while you're on the move anyway. These arm warmers solve this problem in seconds: they are quick to pull on, can be taken off while riding, and disappear into your jersey pocket afterward.

What these arm warmers do

• Full arm length over the wrist – covers the forearm and wrist, the areas that are constantly exposed to sun and wind when wearing short sleeves.
• Elastic nylon fabric – fits snugly, follows your arm movements, and won't slip down.
• Moisture-wicking material – transports sweat to the surface where it evaporates, providing a light cooling effect on the skin.
• Reflective stripes on the forearm – positioned exactly where the arm moves while running or riding, making you more visible at dusk.
• Thin, flat construction – doesn't feel bulky under a jersey or jacket and won't chafe under backpack straps.
• Packable to the size of a hand – rolled up, both sleeves fit into a jersey or trouser pocket.
• Supplied as a pair – both arms are evenly covered.

Practical for bike rides on cool mornings that warm up over the course of the day, for runs at dusk, for long hours by the water while fishing, and for outdoor training when the sun beats down on your arms for hours.

Don't arm warmers constantly slip down?

The grip comes from the elasticity of the knit: the upper cuff sits snugly on the upper arm and holds the sleeve in place without cutting in. The right size is important because sleeves that are too loose will inevitably migrate. Pull them up piece by piece over dry skin instead of tugging at the edge. After training, wash at a low temperature in a laundry bag without fabric softener and let them air dry to maintain their elasticity.

For anyone who starts out early without having to commit to one temperature.
