snaps covers for padfolding?

[faiths13]

what are the best snaps covers for padfolding flats? something that holds them in nice and snug and is trim? i would prefer sized if there are any....we have flips but they are almost too short in the rise, but the bummis super lite are a good length. so im hoping a sized cover will fit better than os. although i was wondering about the thirsties duos and if they maybe have a longer rise than the flips.
