Castelli discovered the best combination of fabrics along with a minimalist design to create a base layer that keeps a cyclist drier and cooler when his body heats up. The main fabric, Magic Mesh, will not absorb sweat. It simply acts as a medium for moisture to be pulled away from skin. In the Core Mesh 3, a cyclist dries nearly immediately. The mesh’s extreme stretch and less than ¼ pound weight provide a cyclist with a base layer that is barely noticeable. The only thing he will notice is that while riding in the Core Mesh 3 base layer, he’ll feel exceptionally more comfortable. The base layer not only dries body moisture, but it acts as a second layer. The second layer increases air circulation to cool down a cyclist who is riding at a high intensity. Comfort is further enhanced by use of minimal seams. The Core Mesh 3 feels silky soft against skin providing a base layer to help a cyclist feel great on the bike.\u003c\/p\u003e","brand":"Castelli","offers":[{"title":"Black \/ 2XL","offer_id":52092748497216,"sku":"A17027010-6","price":70.0,"currency_code":"USD","in_stock":false},{"title":"Black \/ L\/XL","offer_id":52092748529984,"sku":"A17027010-4","price":70.0,"currency_code":"USD","in_stock":false},{"title":"Black \/ S\/M","offer_id":52092748562752,"sku":"A17027010-2","price":70.0,"currency_code":"USD","in_stock":false},{"title":"white \/ L\/XL","offer_id":52092748595520,"sku":"A17027001-4","price":70.0,"currency_code":"USD","in_stock":false},{"title":"white \/ 2XL","offer_id":52092748628288,"sku":"A17027001-6","price":70.0,"currency_code":"USD","in_stock":false},{"title":"white \/ S\/M","offer_id":52092748661056,"sku":"A17027001-2","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/1943\/3024\/files\/a17027_001.jpg?v=1780703202"},{"product_id":"castelli-active-cooling-sleeveless","title":"Castelli Active Cooling Sleeveless","description":"\u003cp\u003eThe Castelli Active Cooling Sleeveless base layer keeps you cool and dry during hot summer months.
