Hikenture Skull Cap Helmet Liner with Glasses Holes, Winter Thermal Cycling Cap for Men & Women, Cycling Hat Beanie

This helmet liner is comfortable, breathes well and keeps you warm. I really liked the slits for glasses. This lets you take them on and off with the liner on and it does not pinch the frames against your ears.Another benefit is the liner stays on your head it doesn’t ride up or shift under your helmet.Overall it is comfortable, lightweight, and a good value for the price.

I bought this for cool/cold rides > 32 degrees F. Arrived exactly as pictured, snug fit fully covers ears and sunglass slots are well placed. Very comfortable and very warm while still being thin - fits perfectly under helmet. Highly recommend this product - great function for the price

Nice snug fit under my helmet, though a little loose of a fit on my head. But I have a narrow shaped head, so just be aware of that. And it is very warm.

Warmer than the usual Lycra skull caps that most vendors supply.Well-cut to protect the ears (arguably the part of the head that is the most vulnerable to cold).The cut outs for glasses are a SUPERB design feature. They prevent the legs of glasses from undermining the insulation of the skull cap. It works better than one would imagine.All in all, the best under helmet skull cap for cold days.Highly recommended.

I love the weight of this fabric. Heavy enough to be warm on cold days cycling in the winter, but not too bulky to fit under a bike helmet. This skull cap is perfect for rides between 26-40 degrees. Colder than 26 degrees? Forget it, I’m staying inside. I thought the slits for sunglasses was a gimmick, but they work well. Allows you to wear sunglasses, but keeps the fabric close to your ears so air doesn’t leak in. Nice feature that I never knew I needed.

I was hoping for something a bit more snug, it’s overly loose but it fits a bit floppy. I’ll be wearing under a hard hat, it shifts a bit causing the hard hard to move around a bit as well. Going thru other reviews, it appears some people get a way better fit than i didUPDATE: I purchased another one, and this fits like a glove. Definitely much better. If you have a loose fitting one, try getting an exchange. It seems like the QA/QC isn’t perfect but I’m so glad I tried again. When it fits snug, it doesn’t slide around and it traps heat inside. Much better than squeezing a beanie underneath

I wear glasses so I need something that doesn't interfere with them. This is exactly what I needed. Keeps my head warm, my glasses stems slide right in, and it reduces some wind noise(not all, but it helps).The fit is just right for my medium sized head, and the elastic cuff holds it in place. I like that it doesn't pinch my head the way a knit hat can, but still provides the warmth I need while fitting under my helmet easily.I'm also grateful for the reduction in wind noise without drowning out the street noise so I can stay aware of cars.Will definitely buy again when I need another.

This is very well made. I have a large head for my body size and it results in many challenges to find a head covering that works as normally, they just don't. I was surprised and delighted that this did,and vey well. I am fortunate to live in the San Diego area with a benign climate for bicycling, but it still gets into the 40's and the ears can get pretty cold on rides. This solved the problem. It is warm enough but also is thin enough to fit under my Sena bike helmet. Function is always more important than form, but I think it looks good too. Very satisfied.
