Castelli's all-surface riding range; unlimited. For those who ride a mixture of paved and unpaved surfaces, who ride hard and demand a lot from their clothing. The Unlimited Jersey uses everything Castelli know about moisture management, fit, shape, and the convenience of zippers that open easily and pockets that are the right shape and in the right place. But on this jersey they took the extra step of using fabrics that better resist snags from tree branches or vines that you'll find on your favorite trail. The main body fabric is a polyester knit with good stretch and moisture management but better durability than the typical fragile fabric that's OK on the road. Then on the sleeves, shoulders and back panel we use a stretch woven fabric that is extremely resistant, since this is the area that most often gets snagged.
