What is a TOG?

Best for Arm Warmers

All babies and toddlers sleeping arms-out (from around 3 months of age)


Our Arm Warmers are a bolero style jacket, designed to be used over the top of any arms-out sleeping Swaddle, Sleeping Bag, Sleep Suit or Sleep Onesie. If your baby is wearing a sleeveless sleeping bag, you may notice their arms feeling cool during the coldest hours of the night. If this is causing them to wake, a little more warmth on the arms may be needed. The sleeves on the Arm Warmers are rated 1.0 TOG making them suitable as a mid-weight layer, and the foldover cuffs will help keep hands warm too. Size 12-36 months has grey piping and cuffs.

We recommend the Arm Warmers are only used over a sleeveless sleeping bag, not one with sleeves. This will help your child maintain a comfortable temperature whilst sleeping and ensure they do not overheat. Hot tip - on transeasonal nights when it is warm at bed time but cools down during the course of the night, put your baby to sleep in their sleeping bag as normal, and add the Arm Warmers later in the evening before you go to bed. The position of the Arm Warmers on the body will not interrupt the natural sleeping position for healthy hip joint development.

Made with our signature premium GOTS certified organic jersey cotton with stretch for comfort. Natural fibres are better for sleeping for the simple reason they are breathable, and help your little one regulate their temperature overnight. Our certified organic fibres are also skin-friendly and sensitive on eczema and dry skin conditions. All ergoPouch fabrics are dyed with non-toxic water based dyes.

*Note: Size 12-36 months has grey piping and cuffs.
