French Fitness RevolutionHelmet Liner Sweat Wicking Skull Cap Beanie. Ultimate Performance Moisture Wicking. Fits Under Helmets

These are thicker than another set of beanies i bought. I really like these. I usually use these at work since I have to wear a hard hat all day. These beanies hold back the sweat really well. Now to wait till winter to see how they hold up. Great product! Strong and stretchy. Fits really well its also comfy too since im bald and hate the feeling of the hard hat liner on my scalp. Thanks again!

Fits well

So I just got this it feels pretty comfortable put some water on it and definitely had a very good cooling effect but the issue with it is is that they're not very tight they say one size fits all but they're not taking into account if you have a smaller head it definitely doesn't fit very tight for someone like me with a smaller head I mean it's still nice but I wish it was tighter it wouldn't look so wrinkly on the top and would hold my hair in better.

I bought the 6 pack in 2019. I use them for running, inline skating, cycling or just even walking the dog when it’s cold out. They have been washed and dried in the dryer and all 6 have held up perfectly. They fit my head perfect and I have a medium/ large head. Very convenient to carry in your pocket. I have tried Under Armour skull caps and they are too small for my head.

Fit tight and wash well. Worth the premium to have a hard hat liner that is comfortable.

Update 2/18/25: I really needed more of these beanie hats as I lost my last one recently. I decided to order one of each color to see if there are differences, as even recent reviewers state either too small or perfect fit.What I found is, there are three different “sizes” of this supposedly one-size-fit-all product. The second picture tries to visualize that. Red and olive are laughably short. Maybe fit a child’s head. On my “L” head, white and grey just reach the earlobes. OK for most situations but in stormy weather, cold air will enter your ears. Blue and black are the longest and fully close off your ears.I tried to contact the company a while ago about their sizing issue. Never heard back. Sad!In any case, I hope this review helps others pick the right size and avoid their misfits.—-I had purchased two of these beanie hats in the past to fit under a bike helmet and as a light-weight and comfy hat for hiking and outdoors. I lost one of them and purchased a new one.To my disappointment, the current product is very different. Look at the pictures that I attached. The material is over an inch shorter, almost like a kids hat. It doesn’t cover the ears at all (unlike shown in the product pictures). Also, the cloth is different. Previously it was soft and comfu material. Now it feels cool and plasticky, not pleasant for cool weather.I don’t know what changed in their production but unfortunately I’ll need to look elsewhere for a replacement now. I really loved the old model.

Very comfortable and have held up over time. I wear one of these under my cpap and also when I use my Meta headset. They're great for both.

Perfect fit and design…Works well every time. Needs other colors
