LOVE
I love these sleepsacks. They're just snug enough that they feel secure, just thick enough that they keep my baby not-too-wam throughout the night, and are just so cute. We love them!

Our Jersey Sleep Sack is a baby and toddler sleep sack designed for arms-out sleepers usually from around 3 months of age. The Jersey Sack has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'first sleep sack' after the swaddling phase is over. The ergonomically designed sack features a bell-shaped bottom to promote healthy hip joint development and is approved by the International Hip Dysplasia Institute, and the material is stretchy to allow baby to move more freely and stay comfortable while they sleep.

Soft and Roomy
This sleep sack is so soft on the inside and the length is nice and roomy for my little to move her legs around. It’s a very pretty green too

Just perfect
My son has eczema so I’m pretty cautious of what material is on him. I’m so thankful I found this brand! Such a soft sleep sack, love the organic cotton! Just perfect all around

My go-to
My daughter loves her sleep sacks! Just bought this one since she was growing out of her previous one, she’s obsessed with pink and could not put it on fast enough.

Great Product
Fabric is soft but durable. Love the TOG rating listed on the outside. As a side note the fabric is also very absorbent keeping leaks from diapers away from baby.

Quality sleeping bag
Have purchased a fair few sleeping bags / swaddle bags the past few months as bubs grows out of the sizes so quickly. Love the ergopouch design and material. This one I got in the 8-24month size because I have a very big 5 month old that already meets the minimum weight and height. It fits perfectly and keeps him warm enough on the cooler nights. Very happy
