The lightweight Halo Cycling Cap has quickly become our favorite mountain and road bike riding gear. The cap fits comfortably under any helmet and the flexible visor keeps the sun glare out of your eyes. The cap can also be worn with the visor in the UP position. The smooth mesh top breathes well and it can be worn for year round comfort. The stretch fabrics allow it to be worn above or over the ears and it will not lose shape, form, or stretch out. Made in the USA, one size fits both men and women.
