Castelli's work with GORE-TEX has been exceptionally fruitful, especially with the advantages and variants of the INFINIUM WINDSTOPPER fabric. Building off the popularity and success of the Perfetto RoS Glove, the design team at Castelli tapped into the Stretch High Loft fabric offered in in the INFINIUM WS line to create a warmer version of what had been the best overall winter glove Castelli had offered. Enter the Perfetto Max Glove. The upgrades from the Perfetto RoS is that the Perfetto Max has a thicker, warmer fleece on the inside and extends farther up the wrist. Other than the extra warmth, both gloves feature the same wind and water protection, the comfortable thermoformed single-seam construction, grip and durability overlays on the palm, and touchscreen zones on the fingertips. It also carries the a stretch wrist for easy on-off action and the CDS damping system, which protects the median nerve while gripping the bars or controls. The Perfetto RoS Glove covers a wide range of conditions, but if you ride in colder weather or suffer from cold hands, the Perfetto Max is the solution.
