TLDR: These are the SIO (Snap-In-One) System covers with extra snaps on the inside to fit SIO Inserts (Bio-Terry and Cuddly & Snuggly) and Leaklock Pockets (that you can stuff any Puppi Inserts inside)

If you're looking for the regular covers (without internal snaps) go here

Newborn - 6 to 14 lbs
Mini One Size - 10 to 21 lbs
One Size - 13-33 lbs
One Size Plus - 22-40 lbs

Size Guide: If you are looking for a wool cover that fits perfectly on a newborn and on a baby up to 2-3 months old, the newborn size will be the best choice. PUPPI Newborn wool covers fit babies up to about 6.5 kg and provide a perfect fit and no big bottom effect. Well thought cut allows proper airflow in the diaper, and ensures that our wool cover will fit on any absorbent insert and PUPPI fitted diaper in Newborn size.

Mini One Size wool covers are a solution for all parents, who plan their first try of cloth diapers not earlier than when the child reaches the weight of 4.5 kg, for all those who have very small children and for all those who do not use the universal size and want the diaper to be best suited to the current weight of the child. The Mini One Size Wool Cover will fit well from 4.5 to 9.5 kg.

You may find that One Size covers look small when they arrive. But, fully stretched, they are the size as any other One Size cloth diaper. They are fairly narrow, so those who require many layers for night time may find that these are not the best night solution for them. If that is the case, the One Size Plus Puppi covers offer more width.

When it's a good idea to choose a One Size VS a One Size Plus?

A One size SIO wool cover will be an ideal choice if:

  •     milk poops happen to your baby infrequently or not at all
  •     your baby is a small, running away "octopus" and it is difficult to change the nappy, and you are looking for a solution to do it efficiently and without fuss

One-size plus cover will be the perfect choice for you, if:

  • You are just starting using cloth diapers and your baby is aready around 20kg.
  • You are looking for perfect wool cover to use with our Puppi fitteds in One Size.

Wool cover is an outer part of a cloth diaper which is supposed to keep the moisture of absorbent insert inside the diaper.

When it's time to change the baby's nappy - we change the absorbent insert inside the diaper (or the fitted diaper), and we hang the wool cover for airing. It will be ready to use at the next diaper change.

  •  Most babies need no more than 4 or 5 diaper covers.
  • 100% merino wool
  • Wool produced and sewn in Poland
  • Our wool is prooved to be mulesing free
        - Handmade
        - 4,5-9,5 kg
        - Requires lanolin

Well-thought cut allows proper airflow in the diaper, and ensures that our wool cover will fit on any absorbent insert and PUPPI fitted diaper in Newborn or Mini One Size.

Puppi diaper covers are made of two layers of extremely soft and thin merino wool flannel. Colorful snaps and decorative stitching make this diaper a conversation piece. The leg elastics are soft yet very stretchy, which allows for a trim fit on virtually every child.

Once lanolised, these covers hold moisture very effectively. Wool is an extremely versatile fabric for cloth diapering-- it is breathable, temperature regulating (perfect for both cold and hot days), soft, and naturally antibacterial. Lanolin breaks down urine into salts and water, so it does not need to be washed as often as PUL diapers. Simply hang to dry between uses. However, a special washing and re-lanolising procedure is necessary on wash day.

Our wool covers can be used with any absorbent inserts, cotton flat diapers or prefolds. We recommend MOS covers to use together with:

  • Newborn bamboo insert
  • Cuddly & Snuggly Anatomic insert
  • Bamboo Tri-fold MINI insert
  • Close to Nature bamboo/hemp insert
  • Bio-terry slim fit insert

Long lasting for our dog. I'd buy again.
My wife fills the cups with applesauce, peanut butter and or pumpkin and then freezes it. The dog loves it and keeps him occupied for a little while. All his other toys and chews get chewed up in a couple of days and this has already been several weeks. I want to buy more cups if available. I'd buy it again and will look for similar items.

Durable, hard chew toy
My dog loves this toy!! He destroys everything but this has lasted us months. A lot of times he chews on it without us even filling the cup. Perfect size for a bigger dog like a golden retriever, but our small dog enjoys it too. Very durable chew toy!

Pieces of Plastic When Biting
My dog spent 15 minutes and then the item started to break up. As the dog was biting, little pieces were showing in his tongue. I threw it away. My dog is a lab.
