MISSIONCooling UPF Performance Hat - Unisex One Size Cap for Workouts, Golf & Running - Sweat & Water Activated Technology

The BEST most comfortable hat. I have a small head and it fits my head. I also get migraines and get hot easily and this hat is so comfortable and keeps me cool. It’s high quality and super bendy.

Love the fit, feels light and breathable.

Great cap except in White! My white one turned a yellow off white after a few uses. The cooling effect with water is excellent and the cap is easy to wash. Avoid White unless you like yellowish off white!

Love the material, and style of these hats. I don’t get so hot, in the summer, in these, versus cotton hats. I also have a small head and these easily adjust to fit me well.

I wear a hat 24/7, and I sweat a lot. I was looking for an affordable, washable hat and that’s exactly what this is. The black is jet black, but doesn’t feel too hot out in the sun. If it does get hot, “wet to cool.”In case it’s relevant to you, you can fold this hat up into the bill. The bill is stiff, but the hat part is a thin, foldable material.

Hats are great BUT:THERE ARE 2 SIZESSmall/Medium AND a 1 size fits allIt’s RANDOM as to what size they send meI keep returning the SMALL/MEDIUMS….

This product is exceptional. It does exactly what I states it does, its lightweight, well fitting, well made and extremely comfortable to wear. After purchasing one, I went back andvirdeted two more!! I rarely write reviews but this hat is well worth sharing about!

This hat fits my large melon fine. I was concerned with some of the reviews stating their hats are indicated as being S/M. I figured with the Prime deal and the difficulty I have had with finding a lightweight, tan/khaki colored hat for summer, I will order one and take the risk. I am glad I did. It is a very thin, lightweight hat and even with the S/M sticker and tag, it still fits my large head. For reference I have a few UA fitted hats that are L/XL, and this Mission hat fits fine. I just got it, so not sure how it will hold up, but for now I am happy.
