CastelliMen's Nanoflex 2 Bib Knicker(Return to Product Page)

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.

I have been using the Castelli Nanoflex knickers for three years now. They perform excellently during cold and rainy weather. Water repels off of the material and keeps your butt and thighs dry. They are also quite breathable thereby preventing overheating.

At 5'-7 and 142lbs, I most often buy a size small, so I upsized to a medium, but they were still too tight and the straps were shorter than normal. The pad feels good and the construction is good.

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.

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

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.

Great fit, great warmth, excellent quality.

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.

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.

These are great for cooler temps due to the thicker material.

I'm normally a large in other brands but have to go to 2xl with the bib due to the strap length!
