i went out for an hour and a half run. and i wore my light-weight camoflage hat. and it prooved to work rather well, because i have hair down to my nose. if i woulda not worn the hat my hair woulda been all over the place/ in my face/ anoying me. it def. keeps in heat i took it off a couple times to air my head off after that i was fine.
Get, the lighted hat im sure it will come in very handy. esp in the morning when theres no cars out and you cant see anything!
