Karen's comments: These are not the same fit as the Thirsties sized Cover . The fit of the Duo is trimmer and the size runs differently. I don't want people assuming they are the same as the others but with rise snaps when they really do run differently - this one, the Duo, is narrower and trimmer. Size 1 works with Cloth-eez prefolds sizes Newbie through Small; size 2 works with Cloth-eez prefolds sizes Intermediate through Large. Workhorse size NB and Small for size 1 Duo Wrap, Workhorse size Medium and Large for size 2 Duo Wrap.
I think the size change might come at 15 pounds not the 18 pounds recommended below (baby shapes vary of course, so weight recommendations are always a rough guess). Great over unpinned prefolds (pad folded and just laid in the wrap) A no-pinning delight! Also lovely over fastened prefolds or use over fitted diapers such as Workhorse diapers.
100% polyester with TPU laminate FREE of VOCs, PVC, phthalates, lead, and latex. Made in the USA.
If your toddler outgrows the size 2 cover, check out the Thirsties Cover in size Large. It has enough room inside to fit a very thirsty diaper. Thirsties Cover size large (not the Duo version) is the next size up from the Thirsties Duo Wrap size Two or the even bigger Duo Wrap Size Three instead. Thirsties Duo Wrap size Three is our largest cover.
Fit tip - always put the extra fabric up when using rise snaps.
