This is the smallest umbrella I could find on Amazon. 5" when folded, so I can put it in my jacket pocket just in case it might rain later in the day. Very light also. I hope it holds up. For the lifetime warranty, you need to send in the umbrella and $5. When my tiny Rainlax broke, it didn't cost any money to replace. As long as it doesn't break on me, it gets a definite five stars. I like the bright green/yellow one I got so that drivers can see me well.
