The Sleep Suit Bag should be fitted around the neck and the armholes to avoid your child slipping through. In 'legs' mode, there should be enough length at the end of the suit to allow your child to move their feet freely. 2.5 TOG and 3.5 TOG Sleep Suit Bags should not be used in a 5-point harness or car seat for safety reasons.

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!

I was excited to get your product, but unfortunately it won’t work for my situation. I would have thought that you guys would supply me with a return shipping label. I was not and it cost me 18.00 to ship it back to you. I regret ordering it entirely!! You should not expect customers to pay that much for returns

This is the 4th or 5th Ergo sleeping bag we’ve bought for our granddaughter since she was born. She loves her sleeping bag and now gets it herself when she’s feeling sleepy or for her midday nap. Even at the age of 2 she is still using it, as she would tend to kick off sheets and blankets and then get cold. Definitely a worthwhile purchase!
