Stay cool and keep pedaling in the De Marchi Men's Short Sleeve Superleggera Base Layer. Made to layer stealthily under a cycling jersey, this base layer is touted as the perfect pairing with a technical jersey within a temperature range of 64 to 77 degrees Fahrenheit. While that may be its sweet spot of intended purpose, we feel that's awfully specific and have had luck using this type of base layer under a wide variety of jerseys and jackets for year long comfort on the bike. De Marchi fashions the Superleggera from lightweight, breathable polyester mesh to wick away sweat and keep you dry. Its rounded neck sits comfortably against the skin and a semi form fit reduces bunching when paired with your favorite bib shorts and jersey. It's also worth noting that this base layer is made in Italy from Italian fabrics. Not only is it durable, but it's also framed with the impeccably classic De Marchi design.
