Thirsties Duo Wraps - Now Available in Size 3!

Thirsties Duo Wraps diaper covers were originally designed to fit babies from birth through the potty training years with their perfect two-size diaper cover system. Based on customer feedback, the Thirsties team realized there is a considerable need for a larger option in the Duo Wrap line to fit babies and children in the 40-60+ pound range. The size one and size two, slim-cut Duo Wraps with the adjustable rise and signature leg gussets you love so much now has a bigger sibling, Size Three! The size three Duo Wrap provides the same superior leak protection as its smaller siblings, just bigger!

Trim Fitting Leak-Proof Coverage

Trim fitting Thirsties covers are a smart selection for families using prefold diapers. Folded and wrapped around baby or trifolded and laid into the diaper cover, Thirsties Duo Wraps' leg gussets provide the leak-proof coverage and protection needed. The super-soft leg bindings are an added benefit against baby's sensitive skin.

The Duo Wrap also pairs well with your favorite fitted diaper.

Your child's delicate skin needs a breathable, yet waterproof diaper wrap!

Thirsties Duo Wraps may be lighter on the budget, but they didn't cut out any of their great features to get there! Completely waterproof, Thirsties Duo Wraps are still breathable, pliable, and comfortable for baby. Secured around baby's waist with durable snap closures, diaper changes are easier and baby gets a comfortably snug fit every time.

Thirsties Duo Wraps grow with your baby!

Sizing up Thirsties Duo Wrap Diaper Covers

  • Size Two - 18-40 lbs (8-18 kg) 9-36+ months

Definitely BIG!

Finally! A diaper that I can put on my 21+ lb 7 month old and it is still on the lowest rise setting! It has plenty of room to stuff with all sorts of overnight goodness while she is this size. If you're looking for a big diaper cover, this is it!

These rock! DD is 4, 38lbs, DS is 2, 41lbs(little giant, haha). This is our night solution with two flour sack towels in the kite fold with an additional pad folded fst. Neither have leaked and this cover will last a long long time.

Hooray Size 3!
Reviewed by: (Verified Buyer)  from PA. on 5/30/2018
When the size 1 is on it's fullest rise and baby fills the size 1, then you can use the size 2 on it's lowest rise. The same concept applies between size 2 and 3. My daughter is on the largest rise of size 2, the waist with two snaps exposed. The size 3 fits GREAT on her on the lowest rise. I think Thirsties did a wonderful job at keeping their sizing consistent in this respect. I would say from what I've observed from other diapers, if your child is nearly outgrowing OS diapers, bigger/super covers, or size 2 covers of common diaper brands, and you don't see potty training in the forecast anytime soon, definitely get yourself some 3's! I particularly like the size 3 for my daughter. She is day trained and while she could fit in a size 2 on the largest size, with a big nighttime diaper, she needs the extra space the size 3 has to offer. Considering she only wears them nights, I only need maybe two covers too. And I don't have to worry much about how long it takes her to hold her bladder overnight because the size 3 will last a long time!
