I have 3 lge peapods & I haven't had any issues witht hem at all. I got the second hand also & they are hemp.
BUT Isla is not in the "lge" weight range & I bought her a Med & had nothing but troubles with it. It wicked really badily.
contacted Peapods & all we could come up with was that the medium fit was just not right for Isla & to stick with the lge & cross over the wings.
