Reviews over the

Castelli Nano Flex 3G

The product works as expected.

Pros & Cons

Perfect mid-season wear that will help usher in winter riding

Pros & Cons

Closes well around the arms

The description is correct, size chart also good. They are of good quality and due to the material use and fit do not sag and just to be on the safe side there is a silicone edge on them but is not even necessary. Small size is well suited for long thin arms, which is sometimes different. Sleeves of the Castelli endurance jersey fall well over it and a gabba over it and you are ready to 0 degrees

Pros & Cons

By now worn in various conditions with sun, wind and rain. In doing so, it does what it is supposed to do and makes it the ideal all-round arm piece for autumn and spring. In winter on really cold days, I use them as extra insulation under my winter jacket

Pros & Cons

Great material for use throughout the year.
