Don't confuse this sized cover with the Duo Wrap. This one does NOT have snap rise adjustments. This is a true sized cover which comes in sizes XS through Large.

When Thirsties Duo size 2 is getting too small on your toddler, the size Large cover is the next size up.  It has room enough inside for a nighttime diaper.

The size LARGE of this Thirsties Cover is larger than the Thirsties Duo Wrap size 2.

A true-size diaper cover with snap closure. What is "true-size"? True-size or sized means that it comes in each size, Xsmall, small, medium and large. Unlike an adjustable rise cover or a one-size-fits-all cover, it doesn't have rise snaps, Not everyone likes the bumpy rise snaps on the front of adjustable covers, nor the bulk of the cover fabric in front when the rise is snapped down. This cover is sized so it is made to fit the actual size without rise adjustments. No cover bulk up front! The shape of the cover is not the same as the Thirsties Duo Wrap. It is roomier inside. Don't size up with this cover because it is generously sized. The XS cover is really nice over newborn fitted diapers. It is too big on small newborns, though.

The waist does still adjust since there are many waist snap selections to choose from. I find that not having rise snaps on the front does have an advantage for me when I hold the baby next to my body. It is more comfortable for me. I also think that true-size covers such as this are a bit less confusing for caregivers. It has gentle leg gussets and exposed laminate inside, also known as a wipe-clean interior.100% polyester with TPU laminate. FREE of VOCs, PVC, phthalates, lead, and latex. Another quality CPSIA-compliant, made in the USA diaper cover choice from Thristies.

The size Large is a big cover. If baby has outgrown the Thirsties Duo size 2, the size Large Thirsties Diaper Cover is the next size up after the Duo size 2. It is also a good nighttime diaper cover because it is roomy enough inside for extra doublers.

snap front diaper cover Small pictured. Very adjustable waist and it has leg gussets.

medium prefold Size medium cover with size medium red edge prefold. The prefold lays right in there at full length without folding it down easily. This is a roomy cover. Great for pinning or snappi fastening. The size medium fits over the size large Workhorse. Small will fit over small or medium Workhorse. XS works with newborn or small Workhorse. XL Workhorse will work under either the medium or the large cover but I prefer it under the large cover but it depends on the baby's shape. What works with what is variable depending on baby's shape and your preferences for how you like things to fit. Give pinning a try! It really works.

Overall great except white parts stain

Very functional, comfortable for baby. I was disappointed that the white elastic parts stained from BMs and the Bummis covers with first 2 kids never did this.

Great fit

These XS thirsties diaper covers fit our newborn great. We have had no leaks or blowouts using these where we had several when we were using disposable diapers. We are very happy and will purchase larger ones when baby grows out of these.

Perfect for overnight

I've used Thirsties Duo size 2 covers for years now (3 babies so far), and always wished there was a little more "room" in them for night time use. I just found the large sized Thirsties cover and love it! Wider between the legs so stuffing an extra doubler is no problem - the gussets still fit snugly. Covers the large and extra large workhorse nicely too! (I found the Duo cover to be a little too narrow for good workhorse coverage) No leaks.


I have the oak and acorn cover size medium and it is my favorite cover for my chunky baby!

I have the oak and acorn cover size medium and it is my favorite cover for my chunky baby! It started fitting him around 13 lbs and still plenty of room at 18 lbs (6mo). We use the blue edge prefold with snapppi. A trim diaper with full booty coverage.


I love these covers.

I love these covers. I wish I had known that these existed with my first two kids. I always hated that the Duo covers were so big for such a long time before they finally grew into them and wished they came in more than two sizes. Baby #3 is just about to outgrow the XS and I'm here ordering the next size up. It made it SO much easier to cloth diaper her as a newborn when I wasn't dealing with the too-big Size 1 covers.
