Very happy with this product. I wear this on my morning bike commute when it's cool out, and it fits easily under my helmet. Keeps the wind off my ears while remaining breathable, and I can easily flip the flaps up over my ears if the temperature goes up.

Perfect lightweight headband. I use this under my helmet while bike riding. I hate cold air in my ears. This headband is plenty warm but not too much. I was skeptical of its warmth since the fabric feels thin but it’s the perfect for those cool weather days and the lining is so soft. I’ve work this while running as well. Stays in place, not too tight and wicks sweat.

Product was perfect for my run. Super light material but kept my ears covered from the wind and cold. I'm so happy I made this last minute purchase for my April run where it was 26 degrees at the start time.

These headbands are great! I was really skeptical because they are thin and very light weight. However, I use them for cycling outdoors in temps 35-45 degrees Fahrenheit. They were thin enough to fit under my helmet but still kept my ears warm. And more importantly they kept the cold wind out!
