For wet and cold conditions, Castelli's Nanoflex 2 Bib Knicker 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. 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 tightly. A KISS Air seat pad provides excellent comfort with its anatomic shape and continuously variable thickness, and the knickers stay securely in place with mesh bib straps up top. Features reflective accents front 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.

Very comfortable and warm

I usually wear a medium (in Pearl Izumi) but ordered a large based on other reviews. Sizing up was the right answer and these bib knickers are extremely comfortable. Rode in 3C to 5C (37-41 F) and my legs were at a perfect temp.

Good Bib Knicker

Definitely need one size larger than you would normally use. The 34 length is good as the rest of my skin is covered with a mid length wool sock. Only issue is that the straps seem short. That is unusual as I am short

Nice knickers but Castelli logo peeling off

Typical Castelli comfort and quality (mostly, more on that in a moment). Have been wearing in low-to-mid 40's temps and I'm comfortably warm. Chamois is good, nice snug fit.

Another reviewer said theirs run a size smaller than other brands. I would say almost 2 sizes smaller. I wear medium bibs in other brands and my XL Nanoflex bib knickers are VERY snug.

WRT quality, I've worn these bib knickers twice and washed them in a cold water load after each time, then hang to dry. The Castelli logo on the leg is already peeling off. Disappointing to pay this much and already peeling.

My first knickers, probably not my last

I've never tried knickers before these. I've always used either shorts or tights. But it's been a warmer fall than normal so I thought I'd give them a try.

I've now done a few rides in these and I'm fairly impressed. They're definitely a little cooler than tights but still keep my knees warm. The Chamois is not quite as nice as some of my other shorts but it stays in place fairly well. Overall, they're fairly comfortable.

Sizing is typical Castelli. About a size smaller than most other brands.

Works for me as advertised

I'm a snow bird. Out riding in the rain in the desert and was amazed to watch the rain run off like a waxed windshield

Also the shammy is a good fit for me. Bought these to,warm my knees for early morning rides and was impressed overall.

Even better than its Very good predecessor

Typical Castelli sizing, get a size larger than Pearl Izumi. Compared to the previous one the thighs are a tad tighter and the pad is perfect - padded where it counts and otherwise imperceptible. Good temperature range - low 40s to mid 60s.
