This helmet cap does an amazing job at keeping my head and ears warm on rides down to the 30s. From the size chart I fell between a regular and large so went with larger size. Wish I had stayed with the smaller version because the larger size is a bit loose. There is very little stretch in the fabric so getting the right fit may be difficult.
I was looking for a helmet cap that would keep my ears covered as my old cap would "ride" up over time, exposing my ears to the cold. This cap provides this - so it solves that problem. Unfortunately, what I assume is part of the wind stopping material makes it hard to hear when even in slight wind. None the less, I'd buy it again.
I wear this cap all the time when riding in the winter. I go out for multiple hours in temps below 30F degrees, and this cap is always on. It's a little thicker than the Castelli Cap I have, but goes under my helmet perfectly and keeps me very warm.
I really like this beanie super warm when dry and fits great but when I climb hills and it gets sweaty and wet it doesn't keep my head warm 30-40 degrees.
I needed this product for cold winter riding and was unhappy with the fit of other skull caps. This one has proved servicable to below 40 deg and has a nice tight seal around the edge. Only thing I would ask for is a size between S and L and $10 less expensive.
I have been out with the Windstopper Helmet Cap with wind chills in the mid 20s. Michigan winter came early! This cap does the trick. I use to have to put Cotten in each ear to stop earaches. Not anymore. Now I can hear traffic around me without a massive ear infection. Thanks so much to Gore.
Great fabric, great fit, fits beautifully and comfortably under a helmet. I don't love that the logo is front and center but otherwise this is a perfect lil gem.
