Thanks to its unrivalled breathability, the Castelli Insider Jersey will keep you cool when you go through the gears training indoors.
Bred from Castelli’s world-renowned experience crafting jerseys that will keep you cool on the toughest midsummer mountain climbs, the Insider Jersey is a highly technical garment that has been developed explicitly to keep you cool on your indoor training regime.
Without wind against your skin and with higher ambient temperatures indoors it’s crucial to keep your body temperature optimal if you want to perform at your best and get the most out of your indoor training. The Insider Jersey’s entire construction lends itself to unequalled indoor performance potential.
The 3D mesh polyester fabric utilised across the jersey is not only ultra-lightweight when worn but offers you maximal moisture-wicking and quick-dry properties meaning that any excess moisture is lifted from the skin, keeping you cool and comfortable, even on the toughest surges. The short waist cut, low collar and full-length zipper add to the overall ventilation and mean that the jersey can be effortlessly slipped on and off. The fabric itself is perfectly balanced between transparency and opacity making it suitable for group training sessions or use at home. Two pockets on the rear are great for storage of indoor training essentials such as earphones, headbands or gels.
Because the jersey is the product of a singular drive for maximal breathability and cooling whilst retaining a considered aesthetic, it’s also great when used outdoors in hot weather. You’ll be sure to choose it on midsummer mountain escapes as well as on the turbo trainer.
