Gain an advantage over the rain.

Nanoparticle waterproofing is quickly helping us gain ground in our ever constant struggle to combat the elements while riding. Castelli's second wave of Nanoflex bib shorts combines their water-shedding Nanoflex fabric with a KISS Air seat pad that offers all day comfort with its anatomic shape and continuously variable thickness for natural-feeling contours. Mesh bib straps provide a secure and breathable fit, and reflective details at the sides and rear increase your visibility in low light.

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.

I love these. Great for winter, chilly fall and chilly spring rides.

In the rain they are good too. Not water proof-but when it rains a little water beads up on the surface.

They have a long cut and excellent grippers which are ideal to wear with leg warmers.

pI 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.p

Best rain short EVER!

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.

Comfortable chamois, warm enough for 40-50f rides, runs a bit longer down the thigh like other castelli shorts but that helps keep the leg warmers in place.

Wears too fast.

I was elated when I first wore these shorts. Fit was great, warm and new pad is great. BUT! I was only able to wear them twice. Was going to wear them again this morning but found and felt a very wear hole start to develop. Since I hate chaffing I dont want to wear again. Hoping for a warranty exchange.

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.
