What can you expect from the Castelli Nanoflex Arm Warmers?

  • Water -resistant NanoFlex fabric
  • The same breath ability, stretch and warmth as Castelli's standard Thermoflex warmers
  • Great in every possible condition

Castelli - You know you are getting an unfair advantage!

***** on 13/11/2014

Incredibly good water resistance and protection from the elements. The fleece lining really does make a difference when the weather turns south.
One thing that is worth mentioning is how wrong the castelli size guide is. I'm supposed to be a size small according to their size guide, but I just about fit a large, and even that is a bit tight.

**** on 11/09/2014

Very warm, good non-slip grip. Sizing is a little off.. smaller than the equivalent Castelli jacket (maybe size up)

***** on 03/06/2014

Absolutely fantastic product. Kept me warm and dry in drizzle and light rain. Wish I had bought them sooner. Fast delivery & service from Merlin as usual

***** on 09/05/2014

Excellent armwarmers. Really snug fit and stay up well. Take care with sizing though as I don't feel as though my arms are particularly big and the XL only just fit. I initially went by the Castelli size guide and ordered the Large but they were way too tight. I wish Castelli would be a little more generous on their larger sizes.

***** on 23/01/2014

Super Close Fit. Very comfortable on long spin. Warm and breathable. Paired with the Gabba SS jersey perfect gear for most days this time of year

***** on 20/10/2013

These are spot on, my wife loves them kept her warm and easy to take on and off, can also just keep them in the back of the jesey incase needed. Sizing fitted perfectly from the size guide.

***** on 13/06/2013

Warm , comfortable and keep the showers off
