Have owned a number of goretex rain hats (usually until I lose them) but this is the one I would re-purchase if I ever lost it.

All season, comfortable in summer or winter.
The fold down ear muffs really come in handy when the wind starts to blow a chill.
Well made, Good fit, comfortable on head, chin strap keeps it on in the wind.

Folds nicely into packet, jacket or pack.
