    Go Nano.

    Rumor has it Castelli is working on a portable pedal-powered force field that will protect you from rain and wind when you're riding, but it's still in the test phase, so they wheeled out the new Nano Flex Pro Bib Tights to keep you dry while they run through some more R&D. It's a simple, elegant solution to a difficult problem: how do you stay dry when you're riding in a rainstorm?

    The obvious answer is "Wear hard-shell rain gear", but that leads to sweating and eventually sogginess. To prevent sweat buildup, Castelli built the Nano Flex from the fabric of the same name, a stretchy, warm, and soft blend of polyester and spandex, and then infused it with silicone nanofilaments, which make the fabric virtually waterproof without inhibiting breathability.  Accordingly, you can wear the Nano Flex Pro on its own when its drizzly or under Castelli's new Tempesta Pants — which are a more traditional rain shell — when conditions are really bad.

    On the thighs, knees, and rear, Nano Flex Light overlays provide extra water resistance, while a waterproof and reflective band at the inner leg keeps wheel spray away from your legs and ankles. All the Nano Flex's panels are joined with reduced seams to eliminate bulk and discomfort, and Castelli's Progetto X2 Air chamois keeps you comfortable in the saddle even if the ride is grueling and the weather straight up nasty.

    • DWR-treated material repels water while breathing
    • Chamois included for comfort through base miles
    • Reflective details help keep you visible under overcast skies

    insanely small size

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: XL

    I'm 6'4" tall and thin (35" waist) about 190lbs. I could barely get the XL on. I am used to Castelli sizing their gear a size or two small, but this was crazy. I couldn't even zip the calf zippers, and I have pretty narrow calves.. Size up one or two sizes... I wanted to like this, but the fit was just crazy.

    Yes, size up +2. Italian sizing -is- different.

    And... @Guy, I don't think it is a bad design. It is a great design. Just no design can fit every body type.

    Tip (online shopping reality): Order two sizes. Return the one that does not fit. (Or both if neither fit.) CC has an easy return procedure. Ride dry and happy out there!
