I'm just starting out (a little over a month in!) and I definitely have some preferences already, though I haven't tried many brands.
I'm liking the fit of Alvas and Kawaii best so far. I like the flips with velcro (with a flour sack towel and mf insert, or two of the mf/bamboo inserts). Not a huge fan of the Bum Genius 4.0 with snaps, honestly..I know most people love those!
I'm also finding that it seems to be more the insert that is important - I've only tried microfiber (okay, but doesn't last long), mf/bamboo blend (like these a lot!), and hemp.
what do you like best?
