Nike Fly

Wasn’t able to run very far in this, it’s innovative but misses the mark. Way too heavy to do any serious runs and they ice molds leaked down my head. The hat by its self is a nice comfortable light weight hat. Maybe this would be helpful to wear at the end of a long run. But I don’t see any other practical uses.

Postpartum and breastfeeding make me run really hot, especially in the summer, so staying comfortable on walks has been tough. This cooling cap has already helped me on walks, and the lightweight, breathable fabric makes a noticeable difference. I’m not back to running yet, but I can tell it’ll be great once I start again because it keeps me cool without feeling heavy. The fit is relaxed and comfortable, and the unstructured design sits nicely without feeling tight. The only downside is that the cooling inserts don’t last as long as I expected, especially outdoors, but they still make the heat more bearable. Even without the ice, it works well as a lightweight everyday hat. Overall, it’s been helpful for staying cool during postpartum walks, and I’m looking forward to using it more once I’m back to running.

Standard Fly cap fit, low-depth and snug, which is accurate to how these run. I didn't get to put the cooling system through real heat, so I can't speak to how well the ice actually cools on a hot day. The concept is genuinely clever. Molded ice cubes that sit in crown pockets and channel melt-water down to cool your neck is a smart, specific idea. The Swoosh turning blue when ice is loaded is a fun touch. Reflective details and the bungee closure are nice functional additions. Feels well made. Lightweight polyester, clean construction, and the recycled-material story is a plus. No complaints on build. What I liked most is the idea itself, it's inventive and unlike anything else out there. What I'd change is the practicality for people without much freezer space. The ice molds take up room, and in a small apartment fridge they're awkward to store and prep. This is a product that rewards a certain lifestyle and setup, and that just isn't mine. Cool idea, well executed. Honestly not my style and not something I'd reach for, but I can see it landing for someone who runs hot, spends time outdoors in real heat, and has the freezer space to keep the molds ready. Right product, wrong user in my case.
