That is why we recommend replacing it if you have the slightest doubt. 2/After 5 years of use: The foam deteriorates. It can deteriorate due to impact, where it is stored, the climate, and its use. We therefore recommend replacing your helmet at least every 5 years.

Great hat for hot weather! Good for women with a small head!
Size: One Size, Color: Aurora Plum Purple/Powder Plum Purple/3, Size: One Size, Color: Aurora Plum Purple/Powder Plum Purple/3
This hat is super light weight, breathable and comfortable. It feels high quality and it looks cute. I wore it on a super humid day on a hike and my head felt a lot less sweaty than it does wearing a regular baseball cap. The color is pretty! I also have a problem with most unisex baseball hats being far too large and deep for my head. They usually come down over my ears, but this one fits me really well and doesn’t push my ears down. Definitely would consider buying it in another color.

The hat is just as described. thin, cool and fits me perfectly.
Size: One Size, Color: White/Silver Metallic/3
The fit and color are really good. I was looking for a hat to cover my new short hair cut. Not too heavy so i can wear it in the sun.

Great Hat
Size: One Size, Color: Black/White/3
I absolutely love the adidas Women's Superlite Hat! It's incredibly lightweight and breathable, making it perfect for workouts, runs, or just casual outings. The relaxed fit feels comfortable even after hours of wear, and the adjustable back strap ensures a secure, custom fit every time. What really stands out is the moisture-wicking fabric — it keeps sweat off my face and dries quickly, which is a must during hot weather or intense workouts. Plus, the classic adidas logo adds a sporty, stylish touch without being too flashy. I’ve washed it multiple times and it still holds its shape and color. Whether I'm at the gym, running errands, or walking the dog, this cap is my go-to. Highly recommend for anyone looking for a functional yet fashionable sports cap!
