Perfect weight for running in cold weather. I wore it the other morning when it was 37 and breezy and it was perfect! Not too warm and keep me comfortable. Highly recommend!

My ears felt like they were even colder running with these outdoors than without. And it kept sliding up. Might not fit well over beanies or other headwear.

Very comfortable and fits my head well. I wear it under my bike helmet on cold-ish (40F)commutes. Thin enough to be comfortable but warm enough for a chilly morning.

These are lightweight and comfortable headbands, which I will use for walking, bicycling, and hiking in cold weather.

These are very silky and low-profile, knit to keep out the wind. The fit is comfortable but not loose. They are so small, you can take them in your posket.

Stayed put & didn’t slide. Wore for spring hiking in the mountains. Not "super” warm but enough to keep wind out of ears yet prevented sweating.

I love these for running as they're streamlined and light to carry if I get warm. For biking, they fit nicely under my helmet.

These proved to be perfect to for winter riding (bike, both road and mountain). They look cheap (when you pick them up) due to how thin they are, but have proven to be very durable and the "thinness" was actually a huge help as it fits under a helmet with no issues at all. I've used them through the entire winter season of riding and love them. In extremely cold weather (snow), I simply put both pairs on at the same time. If they ever wear out (or I lose them, which is more likely)…

These are perfect for hiking. I always struggle between being too hot and my ears freezing, but these are light weight and comfortable yet still keeps you warm. You can also roll it back into a headband to still hold your hair back if you start to overheat.

Used this for skiing in 20 to 30 degree weather with a helmet. My ears did not get cold and mine are sensitive. Perfect for use. Will buy again.

I DID NOT RECEIVE THESE FOR FREE, nor would I take or use them if they WERE. While they are soft, the material is so thin air blows right through and the fabric is so stretchy that they don't even make a useful headband. Figured I was getting a bargain, and wanted to get multiples so I could toss them in the laundry and not reuse them for multiple runs. I should have known that you get what you pay for. Very bummed; I had high hopes. Will be returning.

These ended up being crucial for our trip to Iceland. Underneath another hat, they were perfect -- fairly thin, didn't slip around.

These are the perfect balance of thin and light while still providing warmth and shield my sensitive ears from wind and cold. Very comfortable and hold up well over time.

First thought they were too thin to actually work but I was wrong! They work very well in the wind and cold! May not fit all head sizes comfortably.

I got the thin 2-pack as early winter running headbands. I'm an avid running all year, and I don't have many headbands so I wanted to get another pair. The thin bands have a little layer of microfleece on the inside so they're soft, but they are extremely thin. I was concerned they wouldn't keep my ears warm on an early morning run, but it was better than I expected! In the upper 30's I was still sweating underneath the band and my ears were plenty warm.

I got these to wear running outside in the cold. They're a bit on the thin side so they don't provide much protection for temperatures below freezing, but they work well for chilly days. I did notice that they helped with wind tremendously. I ran with a friend on trails by our lake and winds were 25-30mph and this headband really kept my ears from falling off. I also wear slightly bulky wireless earbuds and this headband is flexible enough to fit them underneath without the pressure from the…

Thin, lightweight, comfortable. Don't know if I'd use these on an arctic adventure, but they're perfect for yard work and snow shoveling in moderate weather. P.S. when things get buggy, these keep the mosquitoes and gnats out of your ears!

I bought these for the winter for running. Wanted a little extra protection on my ears other then my hat and this is perfect for that. They covered my ears great, they are very light weight and also does the job of keeping the sweat off me. So far after a couple runs i love these and would recommend them.

Perfect for running, thin and lightweight. Just need it to keep the wind off and keep ears from freezing. 2 pack is perfect.

These are perfect for all workouts. The ear covers kept the wind and cold out on runs. They are comfortable and don’t fall off. However, the extra material isn’t needed for warmer months or indoor workouts and the ear flaps don’t tuck or hide well, which can be annoying.
