    No more goosebumps.

    Cold arms are uncomfortable and distracting when you're pushing through a cool shoulder-season ride, but it's an easy problem to fix. Slide on the Castelli Thermoflex Arm Warmer before you head out on a crisp day, and the microfleece-lined thermal fabric will hold heat next to your arms while remaining breathable if you break a sweat. Features like a comfortable cross-wrap at the wrist and silicone gripper promise to keep fit issues at bay so you can put each warmer on and go ride free of distraction.

    • Insulate your arms on chilly days with this plush warmer
    • Thermoflex fleece holds heat close but remains breathable
    • Silicone gripper prevents slippage and drooping
    • Cross-wrap cuff creates a comfortable fit at your wrists
    • Item #CST00GM

    Next Generation

    • Familiarity: I've used it several times

    Upgraded to these as my go to road arm warmers and fulfilled my Castelli expectations. Thermoflex is super soft and flexible while moving with you during rides, etc. The new cross cut cuff offers a nice smooth and unrestricted closure. As opposed to the Nano Flex version, these are much more elastic and conform to your arms much closer. This can be attributed to the lack of the water-resistance treatment that the Nano Flex versions receive. Fit is Castelli- race fit as expected. My arms are somewhat long without bulk and I opted for medium for a 6'2" rider.

    Very nice - but not for big guns

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: Large

    I have the Thermoflex knee warmers and got these to match. I haven't ridden them in temps below 50 degrees yet, but they seem plenty warm and are comfortable. No falling down at all. I've got long skinny arms, and they're pretty snug and long. I pull them up to my armpits and still go down over my wrists. It works for me, but caution if you've got big or thick arms.

    They do the trick!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    These are a good value and definitely do the trick. Temps dropped today and the arm warmers worked great. These are well made and have a good weight fabric. Inside the sleeves is a nice soft low fleece type backing; comfy. More insulating than your typical lightweight SPF type warmers. I bought a size Medium and they fit well.

    • Size Bought: Medium
    • Height: 5'7"

    It works for me. Very warm! The only cons is that the strap is a little tight and I have thiny arm, but it is bearable.
