The FUTURUM PROFORMANCE Base Layer Xtra Cool is an excellent base layer for summer thanks to the special lightweight Dryarn material. The special structure of the fabric ensures that moisture is removed quickly. This base layer fits perfectly under very tightly cut cycling shirts and ensures high breathability and maximum comfort. The 4-way stretch material ensures a good fit and the base layer feels like a second skin. In addition, this base layer is round-knitted, which means it has no seams. As a result, there are no irritating pressure points that bother your performance. By using yarn made from recycled plastic, we are helping to improve the environment with these base layers. At FUTURUM we say: we like to suffer in nature, but nature doesn't have to suffer for us.
