AMAZON CLOTH DIAPERS!

I'm a FTM and since summer is already here where I live I want something more comfortable for my baby I saw so many cloth diapers on Amazon but have no clue which ones to buy if anyone can recommend me some I'd really appreciate it also some tips!
I have a 4 month old son and we love Dino's lol 
These are the ones I saw and that were cute but don't know if they're great...
