I should have known better. They suck.
I bought 6 sample packs of different diapers from XP. Today I went into my office to get some work done and brought an M4, a Seni, and one Attends. Well, I'm glad my chair is black because the Attends didn't stand a chance. Hopefully my khaki shorts dry before I go home.
Now I'm in the Seni Super, which, if you haven't tried it, I recommend it. I never thought I would like a cloth backed, but they're way comfortable and the regular size is great for tall people with a normal waist size (34"), who want their diapers to rise higher than most mediums (M4 comes to mind) will facilitate.
