What Our Gearhead(R) Experts Are Saying:"I wore the Col de Tourmalet Baselayer under the matching jersey on a hard climbing day and it handled moisture better than I expected from something this lightweight. The extended back cut stayed put the entire ride, which sounds like a small thing until you've dealt with a baselayer that bunches up mid-climb."The foundation of a well-built kit often goes unseen, but it determines everything about how a ride feels from the first pedal stroke to the last. The Santini Col de Tourmalet Baselayer sits closest to the skin and works hardest in the background, pulling moisture away from the body and cycling it outward so the layers above can do their job without interference. It is a simple function, but the difference between a baselayer that performs it well and one that does not is felt on every long, hard effort. Santini constructed the Col de Tourmalet Baselayer from a lightweight mesh fabric engineered for high breathability and rapid moisture transfer, keeping skin dry when output climbs and temperature regulation becomes critical. The sleeveless cut eliminates sleeve bulk under a fitted jersey, and the extended back panel is shaped specifically for the forward riding position, maintaining consistent coverage without riding up or pulling free during aggressive efforts. Minimal chest lettering and a green colorway drawn from the forested slopes of the Tourmalet give the baselayer a considered visual identity that carries the collection's spirit all the way to the innermost layer.
