We tested the Thirsties Duo Wrap with their Thirsties Stay Dry Duo Insert and feel it is an easy-to-use All-in-Two (AI2) system. Aside from extra fabric bulk in the cover, we found this to be a high quality and well-performing diaper as well. It scored a 9 out of 10 in absorbency because of its multilayer insert whose layers snap together. Directly against baby is a stay-dry and stain-resistant polyester microfleece with then 2 layers of fast absorbing microfiber terry made from hemp and cotton to wick away moisture. This snaps together with 5 layers of soft hemp/cotton jersey, the absorption workhorse of the Stay Dry Duo Insert. The thirsties Duo Wrap is not a One Size system. Both the cover and the insert are come in two (Duo) sizes, 6-18 lbs and 18-40 lbs, so you will need to purchase an additional set of each of these as your baby grows.
The Stay Dry Duo Insert has two layers of our fast absorbing microfiber terry, topped with our stay-dry and stain-resistant microfleece and snapped together with 5 layers of our buttery soft hemp jersey.
