Description

For those days when a full skully would be a bit of overkill, but the wind is still nipping at your ears, the Viva Thermo Headband makes a perfect go-to. The fleece-lined ThermoFlex material that comprises it is warm and soft, stretching easily to accommodate a wide variety of domes, yet it's also especially breathable and never lets you overheat. It's raw-cut edges don't bunch and won't apply pressure points to your head under your helmet, making this light cap something you'll almost forget it's there — until you take it off, of course.

Perfect Headband

  • Fit:True to size

Thin yet warm; it's width gives you the option to cover more (or less) of your ears; doesn't bulk up under the helmet; looks really cool. Pretty much perfect, from around 32 to 55 degrees. Very happy with it.

Love it

  • Familiarity:I've used it once or twice and have initial impressions

Super thin, good coverage and doesn't irritate my head like some of the thicker wind blocking caps and bands. This replaced a PI Barrier band I lost which was ok but love the simplicity of this and it's bright!

UPDATE: Maybe a tad thin for 35 degrees but wasn't super unbearable on a 2 hours road ride in that temperature.

Brett B. is right on target. I noticed the difference with this head band at about 35 degrees. It is comfortable and a great addition to a skull cap on a cold day but not for the really cold days. I am happy with the product.
