Medium  18 to 28  pounds

Large   28 to 40  pounds

The Snap version on this page. The Hook and Loop version is here.

Don't confuse this sized cover with the Duo Wrap. This one does NOT have snap rise adjustments and it has more room in the seat than a Duo Wrap.  This is a true sized cover which comes in sizes XS through Large. For an even tinier cover, the Newborn/Preemie size comes in Hook and Loop version only.

When Thirsties Duo size 2 is getting too small on your toddler, the size Large cover is the next size up. Large is bigger than Duo size 2 but smaller than Duo size 3.  It has room enough inside for a nighttime diaper.

Jellyfish and Ocean Lullabies are limited edition prints.

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, XS, 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.

very happy

I love the snaps! I have used velcro for 3 kiddos and it has finally worn out and has become a big issue to fix. Snaps are the WAY to GO!

Awesome cover!

I love the rise on this cover. My baby is slim and quite tall, and so I always reach for these covers for fitting over a flat and an insert for extra absorption overnight. Seems comfy too for baby and doesn’t cause any red marks anywhere.

Great fit, no fuss!

These are a great fit for our 20 mo, 34in and 26 lbs.

Roomier option

I’m really enjoying size large covers on my little one. He is well under the recommended/suggested weight but he has a long torso and I like to boost his nap time large or extra large workhorse. He can still wear a size 2 duo, but the sized cover is wider and roomier when we use a bulkier setup. I like the smooth front without the rise snaps too. The only drawback is that the sized covers come in fewer print options.

Favorite Covers

These have become the favorite covers for my husband and me when we change our 16-month-old. We mostly use Thirsties Duo Wraps which we also love but these are definitely roomier to accommodate our current setup, which is a pad folded one size muslin flat with a pad folded newborn size muslin flat. The snaps are very sturdy, and our curious toddler hasn’t been able to unsnap them yet (he can’t wear Velcro right now unless we put pants over the diaper). While the Duo Wraps are a great economical choice for more sizing options, we sometimes get annoyed with the extra riser snaps that can come undone accidentally while changing a squirmy toddler. These sized diapers are a perfect fit and seem like we will get a lot of use out of them. For reference, our son is 16-months-old and 23.5 lbs wearing a size medium.
