Lightest visor

Party stores have really light ones as party favors. I found this one in a thrift store. It weighs all of 0.35oz/11g and is made with foam.

Seriously?

Well if its serious we should take it that way and adress what you are really looking for in a visor.

what kind of features would you like in your visor?

water proof? you going to wear it under your hood

UV rating? how sun proof do you want it

what size bill? how much coverage would you like

color? bright colors are safer

durability? are you going to bushwack with it

weight limit 1.0 oz

hard bill or soft bill? are you going to put it in your pocket

adjustable fitted or elastic? fitted weighs less

With out the above I cant see a way anyone could properly advise you on what visor to purchase.

Geez, Josh, the guy asked a pretty simple question. Be nice!

David,

I just picked up a Nike Featherlite Visor. Weighs 40g (1.41oz) cost $20
It is pretty slick and I am not sure there is one out there that's much lighter.?

I use the party store one. Cost like $2 and works really well for that and other things along with a bandana.

I think you can get it down to 0.1 oz if you just drill enough holes in it.

My local dollar store has 3 or 5/$1.00 foam visors, something like that. They weigh almost nothing. No protection for top of head or ears, though.

I've been using a foam visor for biking over the last several years. They fit well under a helmet. I used it once for snow shoeing when I didn't have shade for my eyes. I had gotten mine at Walmart and it is thicker foam than what is used in those at the dollar store, or at least the ones I see at my local dollar stores.
