CASTELLI Thermoflex 2021 Arm Warmers ''2''

THERMOFLEX 2 ARMWARMER

 THE DELICIOUS HEAT OF THE THERMOFLEX

Tip: Please keep in mind that Castelli fits smaller than most locally made cycling apparel. Please up-size and note the size charts are merely a basic guide and it is suggested to size up should you fall between 2 sizes.

If you don’t need the extra wet weather protection of Nano Flex, or if you’ve always been happy with traditional warmers, you’ll find that Castelli’s Thermoflex warmers offer the softest, most luxurious fabric combined with careful attention to construction details.

We can officially only rate these warmers at UPF 50+, but in our laboratory tests they actually blocked 99.8 percent of damaging UV rays. We used a polyester base that is not only more effective than nylon at blocking UV rays but is also much better at keeping you dry, which means these arm sleeves are better in both cooler and warmer conditions. We’ve kept the construction very clean to eliminate seams that can rub, and we used our double-sided silicone elastic to make sure they stay in place. They fold up extremely small, so they’re great to stick in your pockets for your next big mountain day.
