great product

paJanuary 30, 2025

This Under Armour Iso-Chill hat is fantastic! I'm a big runner, and I'm always on the lookout for hats that keep me cool and comfortable, especially during the summer months. This one delivers on both fronts. The Iso-Chill technology really does work – I've noticed a significant difference in how much my head sweats compared to other hats. It feels noticeably cooler, even on the hottest days. The ArmourVent fabric is also great. It's super breathable and lightweight, which is exactly what you want when you're working out. I also love the stretch fit – it's snug enough to stay put during my runs, but not so tight that it feels uncomfortable. It doesn't give me that "hat head" feeling either, which is a bonus! The look of the hat is also sharp. It's a clean, modern design that I'm happy to wear both during workouts and casually. I went with the black, but I'm already thinking about picking up another color. Overall, I'm incredibly happy with this purchase. If you're looking for a high-performance hat that will keep you cool and comfortable during your workouts, I highly recommend the Under Armour Iso-Chill ArmourVent Stretch Fit Hat. It's worth every penny. Read more

Super comfortable

Mike WaterburyDecember 27, 2025

I wear a 7/38 fitted hat normally & I got the L/XL. Fits perfectly & extremely comfortable. Can already tell that this will be a great hat to wear with the fabric keeping my head cool. Read more

YipManWillBeatUJanuary 2, 2026

My wife told me she thought this hat looked good on me. She is not one for many compliments either. It fits comfortably and I like it too. Read more

All turned out great!

PRDecember 22, 2025

Never arrives...ok originally 1 star just revised to 4. Although multiple date promises were made, only the last one was accurate. Eventually I would love the hat and finally arrived day before Christmas...PHEW! Nice fit for my husband, and design. Would recommend! Received as expected. 1 star off for delivery. Read more

Love these hats!

DAVID L.September 19, 2025

I’m very happy with these hats. Have bought 2 different colors so far and I plan to get more. I live in the hot humid south and we spend a lot of time outdoors. I have a large noggin and so I have very limited options when trying to find a lightweight/breathable hat that will actually fit me properly. Regular hats look ridiculous on me. These hats are perfect because they are very light-weight and breathable. Best of all, they’re available in different sizes! I ordered the XL size and they fit tailor-made for me. They look great! Also, I’ve put them thru the wash a few times and they come out looking like new. I can’t speak on the long-term durability yet, which is a concern since they are so “light”. But so far I’m seeing no evidence of wearing out or seam issues etc, despite the fact I do not treat things with kid gloves! I’m a bit brutal on my gear. So, all things considered, I highly recommend these hats. Especially if you have a big noggin and need a light weight breathable hat. These are perfect. Read more

Great cap that keeps your head cool.

Hot GuitarJanuary 10, 2026

This cap is perfect. I bought the all‑black version; it looks great, has no obvious logo, and keeps my head cool outdoors. It provides good sun protection, the fabric quality is excellent, and it’s easy to clean if it gets a little dirty. I found it simple to adjust on my head and highly recommend it. Read more
