The De Soto Helmet Beanie works really well. Cycling in hot climates like southern Florida requires keeping the sweat out of your eyes and keeping cool. This works well. One thing - there is a lot of excess cloth at the top for me. It doesn't affect the overall experience, but does make for less than a snug fit.
This is has a comfortable fit and does a great job with keeping your head cool on those hot, summer days. Also, like that this is moisture wicking and keeps sweat from dripping down your head.
For hot weather, this is my go to skull cover. The skin cooler material really does work as advertised. The other De Soto skin cooler products are also excellent - I have several of them.
I have been using one of these all season and just bought two more. It is plenty "long" to come down to the brow where it is effective at wicking sweat. Perfect wicking fabric and very comfortable.
Really stretchy so it fits my medium to large head with no discomfort. Does not cause any heat build up whatsoever and keeps sweat from dripping into my eyes.
I haven't been able to test this in searing heat just yet but it feels good, not too tight and it stays in place. I've recently come to appreciate having a helmet liner in warmer weather, this one does not disappoint.
