    A good base layer will only make your rides better, and Giro's Chrono Base Layer is a classic example of what ultralight fabric construction in a contoured silhouette can do. Constructed with Wikpro, a light synthetic blend, the Chrono is designed to closely hug your body so that it can immediately pull moisture away from your skin, transferring it to your jersey so that it can evaporate as quickly as possible.

    My new favorite

    • Familiarity: I've used it once or twice and have initial impressions

    Great baselayer. Fit was spot on. I bought an XL/XXL (46” chest) and it fits perfect. Great breathable material with a ton of stretch. Wicks sweat well and prevents chaffing from your bib straps.

    Giro Base Layer Fit

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: XL
    • Height: 5'7"
    • Weight: 155lbs

    Great quality base layer from Giro but be aware that these run very small. Definitely go up one size.
