Ready to conquer those in-between days when the weather can’t make up its mind? The Castelli Pro Issue Sleeveless Baselayer is your go-to trusted sidekick, designed to keep you drier than an old joke told by a skeleton — and believe me, I know a thing or two about dry!


Product Features


  • 100% polyester 3D mesh fabric for ultimate breathability
  • Reduced seaming at shoulders for extra comfort, because nobody likes chafing
  • Wider collar designed to sneak under your aero jersey with the grace of a cat burglar
  • Flat waist hem that lies perfectly in your shorts, keeping things smooth and streamlined

Technical Features


  • Weight: 103g, light enough to make a feather look heavy
  • Temperature range: 15°C - 25°C / 59°F - 77°F, your ideal sweet spot

This is the piece our pros specifically called for during those tricky transition periods when the Prosecco base layer feels like wearing a blanket and the Core Mesh leaves you feeling like the ice-cream cone in the sun. Perfect for Spain in February and Belgium in April. You’re not after warmth; you need something that knows how to move moisture away from your body so your race jersey can perform like it’s auditioning for the lead role in a blockbuster. With our innovative 3D mesh fabric, enjoy a little dead air space next to your skin, while the polyester works its magic, whisking sweat away faster than I can dodge a bad pun.
