The Cold-Weather Tight Without Winter Weight

Minimalist meets performance in the Castelli Velocissimo 5 Bibtight. Thanks to extreme comfort Thermoflex fabric along with fleeced Nano Flex stretch-woven lower leg, this tight delivers on splash protection for those especially rainy days.

Thermoflex fabric is the softest, stretchiest winter-tight fabric for lasting comfort. The lower leg gets the Nano Flex fleeced stretch-woven fabric, which is both warm and highly water repellent. The raw edge ankles are zipper-free to reduce bulk, so the tight remains easy to put on and take off. The KISS Air² seat pad and mesh bibs keep your bum and upper body happy, while large reflective detailing keeps you visible.

The ideal tight for most of your winter riding, the Velocissimo 5 is focused on comfort for riding in mild to cool conditions. Mesh bib straps deliver comfort through upper-body ventilation, which is perfect for layering in cold temperatures.


  • Thermoflex fabric from knee to waist for warmth and comfort
  • Nano Flex stretch-woven fabric with brushed fleece inside at lower leg
  • KISS Air² seat pad
  • Mesh bib straps
  • Zipperless ankle to reduce bulk inside shoecovers
  • Reflective inserts on thighs for visibility on back and sides

Hard to go wrong.

Warm, comfy, good stretch, price is okay, nice chamois, look good, mellow branding, appropriate reflection, easy to put on despite no zippers at leg opening. Haven't ridden them in rain yet but previous Nanoflex items worked well in moderate precipitation. Bonus: if you're a socks-on-the-outside type no zipper = no chafing.

Love it, the Kiss Air2 pad is much better than my PI bibtights

I am 5' 8" and a pretty fit 175 lbs or so (not a super lean bicyclists build but not fat either), I bought an XL and it fits great. I mainly bought these for cool, wet mountain biking due to a very rainy spring this year AND to try out Castelli bottoms. I typically wear these when it's 40-60 degrees out and they are just fine, I think I could easily, comfortably ride these in to the 30's (and plan to do so this fall). My absolute favorite thing about these bibtights tho is the Kiss Air2 pad, it is so comfy, I wish I would've purchased these years ago. I have been riding Pearl Izumi bottoms for a decade and they are so-so comfy wise, I just thought they were the industry standard so I didn't think there was better gear out there. Anyhow, here's where the Castellis are so comfy: I live in a valley and most of the fun MTB rides are an hour(s) long climbs on logging roads. With the PI gear I start to get a buttache about 1/2 hour in, but with the Castelli gear I can climb a couple of hours without being forced to constantly change my seating position or stand up on the pedals just to give my bum a break. I've already bought some more Castelli bottoms and they are also very good.
