I get it. You want a cool, breathable hat, maybe for the 4th of July, maybe just for everyday wear. I saw the Usa Grid Trucker Hat and thought, "Easy purchase."
I was wrong. I made these mistakes so you don't have to waste your money or end up with a flimsy cap. Learn from me. Buying a good quality trucker baseball cap takes a little checking first.

I saw one listing for this grid pattern hat that was $5 less than all the others. Big mistake. I thought I was saving a few dollars.
What I got was basically a piece of costume material. The front crown was thin and floppy. It lost its shape the second I took it out of the shipping bag.
When the hat is super cheap, the structure is usually junk. It won't stand up straight. It looks terrible when you wear it.
I focused too much on the cool American grid design. I didn't pay attention to what the mesh back was made of. A real trucker baseball cap is durable.
The mesh on the super cheap version was stiff and scratchy. It made my head sweat even worse. And the plastic snapback adjuster? It was brittle.
I tried to adjust the cap on day one. The plastic teeth broke right off. Now the hat is stuck on one size—a size that is too tight.
Action Step: Look for hats that specify the material. You want a cotton front panel and a strong, non-flimsy adjuster.
The seller photos always look perfect. The colors are bright, the shape is ideal. I trusted the ad photo for the Usa Grid hat completely.
In the picture, the navy blue looked deep and rich. When it arrived, the blue looked washed out and almost neon. It didn't look like the quality cap I expected.
Even worse, the brim was glued weirdly. It sat awkwardly on my head. If I had checked the low-star reviews, I would have seen photos from other customers showing the strange color and bad shape.
