Is the Halo Skull Cap the Best Under-Helmet Option for Cyclists?

If you want sweat control and sun protection without any bulk under your helmet, the Halo Skull Cap is the answer. The 4-way stretch micro-mesh top fits smoothly under any lid and provides serious UV protection, UPF 35 in white and UPF 50 in black, charcoal, camo grey, camo green, and Star Gazer. Halo's patented SweatSeal® channels sweat away from your eyes so you can stay focused on the ride, not what's dripping into them.

In cooler weather, the sides fold down over your ears for wind protection and added warmth, making it genuinely useful year-round. Grip Technology keeps it locked in place, and antimicrobial Dryline® fabric wicks moisture and dries fast. One size fits most. Machine wash cold, hang dry. Made in the USA with a one-year manufacturer warranty.
