I use this hat on a daily (non-winter) basis. It is very lightweight and has a fully vented rear. This hat is very comfortable and keeps my face out of the sun. I'm not fussy with a flat brim style but this hat is designed to be crushed and collapsed and then be able to be shaken out and worn so that is the purpose over a fixed style. Highly recommend this hat if you're looking for some protection from the sun and heat.
