Too often tights are overbuilt, designed for the very worst of conditions where survival is all that matters. The CHPT3 tight is a little lighter and designed to work on 7°-16° days where let’s be honest, some of the best riding can be done.

We have created a tight that works in reverse to shorts and leg warmers.  Our version has a top half that is thermal and a lower part that is lycra, the seam that joins the two swoops down behind the knee giving maximum protection and comfort.  This is the first tight ever to succeed in replacing shorts and leg warmers while doing a better job.

CHPT3 Bibtights 1.13 by David Millar; The CHPT3 Bibtights are a staple item of every cyclist's winter wardrobe. Sometimes we have no choice but to venture out when it's cold or wet, or worse when it's cold and wet. These Bibtights are perfect for winter base rides and feature the same high-performance materials as are in use across the CHPT3 collection.

The upper part is constructed with Castelli’s insanely warm and soft Thermo Flex fabric while the lower leg is covered with the same fabric we use in the top-of-the-line CHPT3 bib shorts. Yes, we have used a short fabric for tights. Why? Because it’s not your normal short fabric, we use a heavier density lycra that offers compression and because of that tight weave offers protection from cold air reaching the skin.

It’s the right balance for warmth and freedom. 

The bib construction is made with lay-flat bonded straps that hold the tight securely without bunching up. And you get to sit on the CHPT3 interpretation of the Progetto X2 pad.

Key Features

  • Thermoflex upper legs

In 2015, the Chpt3 project provided the newly-retired David Millar, and designer Richard Pearce, with the opportunity to work alongside long-time sponsors to create something truly different and exclusive. A collaboration with Castelli launched the brand; a collection of lovingly designed cycling garments that fuse the latest material technology with a sartorial elegance opposed to the billboard stylings of the peloton. The result is the ultimate in both performance cyclewear and coffee-stop chic.
