I love these suits

My baby sleeps in these suits every night and I love putting her in them when we go for our stroller walks

Color fading

I bought 2 ergopouch sacks, one of them 2.5 tog and the other one was 3.5. I washed and dried them according to instructions and they have never seen a sunlight but 2.5 tog one started fading and it’s spreading

It’s ok

First of all the sleeve is very thick and not as thick as other part and I don’t know why design this way.Second the bottom part has two zips on both side but they have gap which is not fully zipped so when the weather gets cold, it has gap where cold air can go there to make sleep bag not as warm as it is supposed to be

Great!

It’s an amazing suit! If I could change one thing, it would be the sleeve length. They always seem to be too short. Even when I buy a larger size, the sleeves are still quite short. Other than that, it’s a fantastic product.

Best sleeping bag ever!

I tried different sleeping bags and Ergopouch is definitely the GOAT! Quality, design, durability and comfort. I feel so happy to see how my bub can sleep warm and safe in it.

Warm but my 15m old is a mover

Nice and warm for bub but my 15m old is a mover and we had the jersey for the 1 tog. She was used to the stretch so we’re still getting used to this one. She moves a lot in her sleep and gets frustrated when she can’t move as easily which wakes her up

Good quality, but hard to get tall child into.

We have used these bags since baby was born, he is now 1yo, and we are finding these new bags tricky to get him in as the zip only goes half way.We are a bit disappointed with this, as he now whinges when we need to put him in his bag, when it use to be such an easy transition.

I like it - but it's hard to get long-legged babies into it!

I like the warmth, colour, material. My only gripe is that the zip at the top doesn't come down very far - when lying my son down, it's hard to get his legs in and out unless I put them in before putting the arms in.

Brilliant design

What a perfectly clever design! These suits will keep bub warm and comfortable in our coming cooler months, including during pram and car rides, and make life so much easier for her parents! Well done, ergopouch!

Really aids with sleep!

My baby never slept through the night - we ordered these as part of his first birthday gifts & the first night he wore it was the first time he slept throughout the night.
