Sleeping bags for kids | Our Penguinbags

Our Penguinbags are ideal to keep walking toddlers and young children warm at night time.
Unlike conventional sleeping bags, the Penguinbags keep the little ones’ feet free to stand in the cot or even to walk safely by themselves.
All our Penguinbags have an outer and lining made of 100% cotton fabric. It has a long frontal zip that allows children to use the toilet by themselves. The zip also slides between the legs and along the lower part of the back to facilitate the nappy change in the case of children who still use them.

Available in 8 different designs that encourage the development of children’s creativity.

Outer and lining: 100% cotton.
In TOG 2.5: 100% polyester filling.

    • For the children’s comfort, all the seams are sewn inwards.
    • For greater safety and comfort of the little ones, we do not use buttons, snap buttons or any other small design element that may go loose. Moreover, they have a neck zip slider protection to avoid rashes and an interior zip protection cover.
    • The main label of the garment is made of 100% cotton and designed to ensure the children safety and comfort. For this reason, they are sewn all around their perimeter.
    • We are very reluctant to the use of chemicals in the manufacturing of children clothes.
    • Due to this, all the fabrics we use for outer, lining and filling are either OEKO-TEX or have been dyed by OEKO-TEX certified dyers.


  • All our products widely exceed the requirements of the European, British, Australian and New Zealand regulations on flammability.
  •  Our filling is made of a material free of chemicals and is not flammable.

  • Toddler Small: 12 months to 3 years / 29″ – 38″ (74-96 cm.)
  • Toddler Large: 2 to 4 years / 34″ – 43″ (87-110 cm.)
  • Junior: 4 to 6 years / 39″ – 47″ (100-120 cm.)




Choosing the right size:

The sizing of our Penguinbags has been calculated so that in the lower side between the legs reaches a point between the ankles (but not below such point to ensure safety) and the knees. Once such lower part is just 5 centimetres under the knees of the child, it is time to move to a bigger size, as otherwise his ability to move will be limited.

All our products are made with 100% cotton. When choosing a size, please take into account that shrinkage of up to 5% may occur while washing the garment.

In any case, each child’s body is slightly different. Please check the chart above for more complete information on sizes.


Our Penguinbags are available in two different TOGs:TOG 1 (for warmer rooms) y TOG 2.5 (for colder rooms, with filling).



Choosing the right TOG

TOG is the international unit that measures the warmness of a garment: the higher the TOG the warmer the garment is.

There are several factors that influence which TOG is best for your child. The main factors are:

  • The clothes the child is wearing under the garment and their quality.
  • The temperature of the room.

TOG 1: Ideal for warmer temperatures between 21 and 23 ºC / 69 – 73 ºF.
TOG 2.5: For room temperatures between 16 y 20º C / 60 – 68 ºF.
