For wet and cold conditions, Castelli's Women's Nanoflex Donna Tight is at the top of the list. Using five-phase nanotechnology treatment, the fabric of these 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. To get the most out of this water-resistant treatment, seams are kept to a minimum, and the ankles feature GIRO3 grippers that lie flat and seal tight against shoe covers. A KISS Air seat pad provides excellent comfort with its anatomic shape and continuously variable thickness, and for easy on / off, YKK® camlock zippers are located at the ankles.

Features reflective accents front and rear 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.

Great tights for cold temps

These are great tights for cold temps. The chamois is very comfortable as is the overall fit. The leg length works well for me (size Small isn't too long on my 5'2 frame). They are not thick like Castelli's Meno wind bib tights (which are super awesome for really cold rides!) but still provide nice warmth and comfort on cold rides. One great feature with no bibs is not having to get half undressed to make a nature call, which is particularly nice in cold weather!
