CONS - I just got it and worn it about 10 minutes when one of the four cotton suspension straps inside the crown tore. Easy fix with glue or needle/thread, but still....Also, my Big Head version is oversized, even for my 7 3/8+ head. I put the adjustable headband on its tightest setting, and it is just barely tight enough, and probably not tight enough for windy days. The chin strap is flimsy, and I'll probably replace it with something in soft nylon and modern buckle system.
PROS - It's very lightweight and comfortable when wearing it inside. I haven't worn outside yet. The price is reasonable, but I'd pay 10 bucks more for better quality control in the suspension and strap system.
Perhaps you guys can consider making a "Professional" or "Working Man's" version for a little higher price, which has an upgraded suspension and chin strap system.
