This is a light weight, low profile cap. I haven't worn it out in the heat yet as I purchased it during the off season. The bill of the cap is pre curved, which can be flattened by simply placing a heavy item on it (Sonos one speaker); the bill won't be perfectly flat, but it wasn't made to be perfectly flat. The tail of the size adjuster in the back of the hat can be discreetly tucked in to a slot in the fabric, which is a nice touch. I'm pleased with this TaylorMade 2023 Circle Patch Radar Hat.
GTown wanted $45 for this hat. A much better price was found here at Golf Vault. I'll be looking at Golf Vault in the future.
