Works as Expected
Color: Black
This Under Armour skull cap does exactly what it's supposed to do. It fits comfortably, stays in place, and works well under a helmet. The material is lightweight and breathable, helping keep sweat out of your eyes during games and practices. Makes it easy to put on and remove helmet. It has held up well after multiple washes and remains comfortable to wear for extended periods. Nothing fancy, but it's a quality product from a trusted brand that serves its purpose perfectly. I would definitely buy it again.

Cool
Color: Black
Been wearing these for about ten years! Nothing better to keep a bald head warm than these. The mesh up top lets your head breathe and dissipate heat. I will miss the wider bland then the thin one now because your head does slip out of it instead of it securing comfortably to your scalp! But I don't know maybe the cost of materials dropped the headband width to what it is now! Anyway, still a great piece!

Great product!
Color: Black
Use this under my hard hat to keep from sliding everywhere. I have bought several over the years and this have been my favorite so far. Will definitely buy again.

Good but if the elastic band were wider it would be great
Color: Black
This is a great under helmet or perspiration barrier for the face during heavy spinning workouts. Sadly to avoid an indentation to your forehead, you must wear it inside out because the sewing band is narrow and tight.
