Kilpi TAIL-U is a cap designed especially for running, cross-country skiing or other activities associated with higher physical performance. The lightweight, super-elastic material with the OPTI-DRY function helps wick moisture to the surface of the material and dries quickly. Flat seams do not press under the helmet. A bonus is the hole for the ponytail. We offer Kilpi TAIL-U in three sizes for women and men, in several color variants with reflective print.Material composition: 95% polyester, 5% elastane
