For wet conditions that aren't cold enough to necessitate tights, Castelli's Nanoflex 2 Bib Short is at the top of the list. Using five-phase nanotechnology treatment, the fabric of these bib tights simply sheds water when the rain starts coming down, but when it's dry, Castelli assures that this fabric is just as breathable and warm as their benchmark Thermoflex fabric. A KISS Air seat pad provides excellent comfort with its anatomic shape and continuously variable thickness, and the shorts stay securely in place with mesh bib straps up top. Features reflective accents on the sides and back to increase visibility.

Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.

Significant Improvement on the Original!

I have used the first version of the Nanoflex bibshorts for a few years now, and was always impressed with their versatility. When you want a bit of extra comfort or a layer thicker than see-through spandex, these are a perfect go-to choice. Adding on to the impressive performance of the original, the Nanoflex 2 has an updated bib cut and material, and more subdued graphics in addition to the KISS Air chamois which is as comfortable as they come. A great spring and fall choice for the Northwest, which can be extended into the winter with use of Nanoflex knee or leg warmers as well.

Best rain short EVER!
by HC Biker

I was skeptical when I first got these, how can a cool weather lycra short be truly water proof, but one ride in the seattle rain convinced me. Water runs off like water on a duck keeping me dry, warm and regulated. Best springtime riding shorts I've ever had.

Improved version

Nanoflex 2 has all the great qualities as the previous versions with the exception of improved lettering process that doesn't appear will peel off. Sizing consistent with other Castelli bibshorts. Water resistant, not water proof.
