Rearz sizing

Quick question, how is the sizing for these, I know that they have a range, but do they have a good stretch to them? Do they seem to fit on the larger size? Going to order a samples from amazon and wondering what soze to order. Thanks guys!

They tend to fit kind of small, so if you're near or in between sizes you should go with the larger size.

Rears are on the large end of fit for length and width per size category (s/m/l/etc), and all of their models have both front and rear elastic, as well as four strands of leg gather elastic and two strands of leak guard elastic on each side. The lower tapes are fitted about in the middle of the back wing, and will have the fit/feel of other diapers with "higher bottom tapes"
