It's very lightweight and flattens out to lay on the dashboard so it will not obstruct my view of driving. You won't be disappointed with this purchase.

The brim is stiff enough that it doesn't interfere with sighting. Wore this hat to the 2021 us formula 1 grand prix in austin, tx.

The brim gets wavy/floppy in little to no time. Even the rim is flimsy. Tried washing and drying flat, low iron but nothing would remove the creases.

Low crown seems to defeat the wanted purpose of the mesh venting. Brim is 3 inches, not 6 inches as previously stated in other reviews. The mesh is useless since it the entire hat falls down on your head.
