COOLING TECHNOLOGY By using hydrophilic and hydrophobic yarns, this base layer holds a bit of moisture next to your body while allowing free airflow through the fabric, thanks to the special open knit. You get evaporative cooling directly on your skin. We recommend using this with our coolest jerseys, like the Climber's or Superleggera, though it will work under any breathable jersey. - Base layer to cool you on hot days - Polartec Delta fabric features regulated drying so that the evaporative effect cools your core - Sleeveless design with minimalist construction - Sublimated overprint - 25°-35°C / 68°-95°F - Weight: 84g

Insulate yourself against the harshest winter rides with Castelli's Flanders Warm LS. Made to withstand your coldest days on the bike, the Flanders features SottoZero Fleece fabric for exceptional warmth. Flatlock stitching ensures a smooth feel against your skin, and mesh armpit inserts allow venting right where you need it. A flat hem tucks easily into tights so you avoid bunching, while the high collar keeps your neck warm and drafts at bay. PRODUCT FEATURES - SottoZero Fleece multi-denier 100% polyester fabric - Flat-lock stitching - Mesh armpit insert - Flat hem tucks away in tights - -4°-10°C / 25°-50°F - Weight:184g

The Prosecco base layers are our mid-weight option and are made to wick moisture away from your body while adding a moderate amount of insulation. This all-around base layer can be used under a short-sleeve jersey to extend the comfort range to those first cool fall days, or even under a full jacket for your intense cold-weather training sessions. - Prosecco mid-weight fabric to keep you dry with a bit of insulation as well - Cut to fit under any Castelli jersey - Flat seams

The first goal of this base layer is to move moisture away from your skin while adding minimal insulation for those cool days when your riding intensity is high enough and your outer layers are warm enough. The areas covered by the bibtight around the waist and up the back can get hot, so we used a lightweight PrimaLoft fabric to help even out the temperature. This baselayer works best when in contact with the skin, so both fabrics are very stretchy and the cut is slim. On extremely cold days we'll use this as a first layer under a Flanders Warm second base layer, or under a thermal jersey. It's very effective at moving sweat away from the body. - Proprietary stretch rib knit 100% polyester main body fabric with Prosecco hydrophilic treatment for maximum wicking - PrimaLoft panels at waist and back where bibtight covers the upper body, to reduce uneven insulation - Crew neck closure to fit under short-collared jerseys
