Alternatives to tams?

Heeeeeey guys! just another quick question! It's really hard to find any reasonably priced tams in my country so I was wondering if there are any other kinda hats to keep dreads in? I've got a really long hat that I think would work great! I'll upload a pic and you can tell me what ou think. It's 100% cotton.

Check ebay or Etsy for wool tams! I got one that came from England and with shipping it was only about $20.00 US!

Etsy has some really good priced ones. Same with Ebay. But why don't you just wear a bandanna?

http://shops.dreadlockssite.com has em as low as 12 bucks

but sure the hat will work for covering your dreads wont help em dread like wool would tho

Bandanna could work! Will check out etsy just don't know if they ship to South Africa! Glad to know the hat will work for covering em. Figured that you could only use tams and that other hats weren't good for your dreads
