On a weekend loop that starts cool in the shade and warms up by the first stop, the Spring Fall Headband P3 covers what the chill reaches first. This cycling headband wraps the ears and forehead in light, soft insulation and leaves the crown open, so heat escapes as the effort builds and the sun climbs. The wide band adds coverage over the ears, and the knit keeps windchill from stinging them. What Our Gearhead(R) Experts Are Saying:"On cool hill repeats, my ears stayed warm at the bottom of every descent, and my head stayed dry at the top of every climb because the thin knit dried quickly between efforts. Once the sun came out, the band went into a jersey pocket and took up almost no room."
