We don't let the low-profile design of the Windham WaveCel Helmetfool us--there's a lot going under that sleek shell to protect our nogginwhile we get in our laps. The WaveCel lining technology features an advanced structure of interlocking cells that provide the rotational impact protection of a MIPS helmet, as well as linear protection--meaning all angles are covered. That coupled with the fine-tuned adjustment system and a comfy fleece lining makes the Windham an easy choice, all season long.
