There is also typically a larger size range (up to 40lbs.) in a two size system compared to a one size system which only range to 30-35 lbs. Combine this size range with their waist extenders they have available for purchase and you can guarantee that they will fit through potty training for even the chubbiest thighs. My daughter fit in the size 2 diaper on the last setting when I only put one insert and/or doubler in, but I love that I can double stuff it for naps and know that I can get a better fit using the waist extenders and that she won’t grow out of them before potty training.
The envelope style pocket opening was pretty easy to stuff and the only downside is that it may be a little messier to clean up messy or loose BMs that get caught in its crevices. The up side is that you don’t need to worry about unstuffing the insert after a messy job or even when it is just wet, because the inserts agitate out in the wash. I did notice, however, that it did not always agitate out when it was double stuffed with two inserts. I found a method that worked for us when we double stuffed: fold one half of the diaper back to sort of peel the cover away from the insert and expose just half of the inserts so the inserts finish agitating out on their own, yet you keep your hands mess free.
The elastic on these diapers was very stretchy and seemed to be snug yet gentle of my daughter’s thighs. There is also elastic under the belly which is always a nice feature so that you get a good fit, yet still allow your little ones to comfortably bend and wiggle around. I definitely think the shape of these diaper hold to its name and they are adorable and trim diapers that can still be customized to the absorption and size you need. The waist extenders I mentioned above also allow the diaper to stay trim for the average or petite baby and only need to be purchased if you need to extend the waist for larger babies.
These diapers are on the pricier side when used as a pocket diaper, but can be used more economically as an all-in-two diaper. You will also save money by buying the kits such as the Starter Kit and they also have a Mini Test kits available with 1 cover and 3 inserts which would be a perfect way to test out the system and save compared to buying the cover and inserts separately. The fact that they sell the kits with more inserts than covers encourages that you use the diapers as an all-in-two system unless you prefer to use them as a pocket diaper.
Closure Style: Snaps, two on each side, vertical.
