Castelli Nanoflex
Castelli Nanoflex
Castelli have two different type of warmers – Thermoflex and Nanoflex – with the main difference being that the latter offer an element of water resistance.
Review: Castelli Nanoflex arm warmers
We’re big fans of the Thermoflex warmers, which we reviewed in spring, but the Nanoflex warmers get the nod here thanks to that water resistance. The silicone-treated fabric repels water and will see off short showers and road spray, making the Nanoflex warmers versatile for when you’re not quite sure what the weather’s going to do.
Review: Castelli Thermoflex arm warmers
Silicone grippers keep the warmers locked in place, and external grippers at the top of both the arm and knee warmers help keep your jersey and shorts where they should be, too.
Price: £30/£35
