Great light weight cap for running. The wind blows straight through it cooling your scalp with ease. Make sure you get the correct size to get a night tight fit otherwise this cap will come off your head. Anyone with thick alive hair (afro, plaits, cornrows, lion manes etc) please try on the last 2 sizes in-store as maybe the largest maybe too large and your hat will move a lot due to the cap being so light weight. And vice versa you don’t want it too small. I have locs levelled cut by my shoulders and I purchased an L/XL when after a few weeks of this size now my locs aren’t fresh so they become thicker, only then I noticed I should’ve purchase the M/L which is all good. I like the hat and will be purchasing the red one next. Hope this helps people with non European hair types. If you have flat hair this hat is a non issue. My Welsh friend owns the hat and she has no issues. She has the first size. JJ
