We currently stock two brands of sized pocket diapers, AMP duo pockets and Fuzzibunz perfect-sized pocket diapers. So here is a breakdown of each diapers' pros and cons.
AMP duo pocket diapers have been manufactured in Winnipeg, Manitoba for several years by Annie Marie Padorie. Fuzzibunz diapers have been around for ten years (an eon in the cloth diaper industry!), they were originally manufactured in the USA, but they have recently moved manufacturing to China.
With respect to the moniker "duo pockets" the idea is that they can be used as a pocket diaper or a cover. To be honest, any pocket diaper can be used as a cover if you feel like it, but I don't really see why you would. If you want a cover, buy a cover, and pay a cover price, not a pocket diaper price. There, so we got that out of the way!
As far as sized pocket diapers go, I have to say, the AMP duo pocket offers a nice fit, especially on newborns (small AMP diapers fit from 7-18 lbs). Fuzzibunz perfect-size diapers in size small are supposed to fit from 8-18 lbs, but in our experience, they run a little large. The large AMP duo pockets fit from 15-35 lbs. On a note related to fit, the AMP diapers have elastic gathering in the front of the diaper, which prevents gaping at the belly. A very nice touch that allows for a great fit on babies with a skinny belly. Large diapers fit from 15-35 lbs, so the AMP duo pocket diaper system requires the purchase of only 2 sizes. Fuzzibunz have three sizes, as mentioned previously, size S fits from 8-18 lbs, size M fits from 15-30 lbs, and size L fits from 25-40+ lbs. Most babies potty train out of size M (roughly 2.5 years old), so realistically, most parents only purchase two sizes of Fuzzibunz perfect-fit diapers.
The pocket opening in the AMP diaper's pocket opening is envelope-style (covered with a flap), so the insert will not poke out. Fuzzibunz pockets are not covered, so you may have to tuck the insert down sometimes. Another thing different about the AMP duo pocket opening is its placement at the front of the diaper, no need to worry about poop getting in the pocket (the pocket opening is located at the back of the Fuzzibunz diaper, although you should be able to just shake the insert into your diaper pail at a diaper change, no touching required!).
You have the option of purchasing AMP pocket diapers empty ($18.00 each), Fuzzibunz perfect size pocket diapers are sold together with a 4-layer microterry insert ($23.95), which is thicker than the standard microterry insert (usually 3 layers). AMP makes a nice bamboo insert ($6.00 when purchased together with the diaper, $8.00 when purchased alone) that can be used as a pocket stuffer, or trifolded and laid in the diaper a la cover/prefolds style. Their bamboo inserts are super-duper trim, and super-duper thirsty (n fact, they're a great addition to any night-time diaper!!
Since Fuzzibunz have been around for over 10 years now, it's a well-known brand, which can affect (boost!) resale value. If you skim the local used ads (Kjiji, UsedOttawa, Craigslist), it's not uncommon to find people looking for used Fuzzibunz diapers. Keep them in good shape, and you can expect to sell them for at least half of their retail value!
