The Castelli Unlimited Ultimate Liner is built for long, rough rides and compatibility with baggy shorts, and pairs comfort with unrivalled ventilation for those planning to spend summer days adventuring.
The liner is built around the luxuriously comfortable Progetto X² Air Seamless Seat Pad. Constructed with two densities of foam and gel pads designed to absorb vibrations and improve ride quality, not to mention a soft upper layer that moves with the skin, this pad offers optimal long-distance comfort.
Castelli's 170g compressive yet breathable Force fabric holds that pad just where it needs to be, while the GIRO Air elastic leg grippers mean you can easily lengthen or shorten the legs to fit under your baggies. Between these two sections, the leg is made from perforated fabric that allows heat to escape and air to circulate freely.
This cooling effect is continued at the top since, like the Free Aero RC Pro Bib Shorts, the Castelli Unlimited Ultimate Liner has minimalist, breathable mesh bib straps that stay firmly in place, thanks to a reinforced yolk.
With all these amazing features, not to mention three rear pockets, this liner gives you all the performance of Castelli's best racing bib shorts, so that you can wear baggies and still achieve the pinnacle of ride enjoyment when it's warm out.
