Mine are bamboo and I change all of my cloth every 90 mins - 2 hours anyway, I can't stand DS being wet, and never had a leak. My friend who uses them though has both the hemp and bamboo and has a 13 month old - she HATES them and says they leak all the time. When I was talking to her the other day, she had her daughter in the red one and sitting on her hip and it leaked all over her in front of my eyes.

I only use Pea pods as my backup, I find them too bulky as I use both the microfibre insert as well as the bamboo booster. Alot of people have problems with them, but it's forgivable in a way because they are quite a lot cheaper. I get them for $17.95 from my local chemist.
