The Sleep Suit Sack 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 Sacks should not be used in a 5-point harness or car seat for safety reasons.

We love our sleep suits so having a size 4-6 is going to be great for this winter and hopefully for a few more years! My daughter is only 3.5yo but is super tall so very grateful for a bigger size as we aren’t ready to go with only blankets just yet.

Great sleep sack. Good quality, keeps the little one nice and warm and plenty of room for him to move grown into. The only thing I dont like is the length of the zippers. Its in a very akward spot and makes changing nappies hard in the middle of the night. Ive given 3 stars as its a big thing for me, I wished I bought the sleep sack instead. Id definitely recommend this for an older baby who sleeps the whole night without the need for a nappy change. Thats the only thing I can fault, the rest is great.
EUergopouch US7/8/26Hi Mandy
Thank you for sharing your feedback. We're sorry to hear you've had a frustrating experience with the Sleepsuit Bag. You have raised some points in your comments regarding its design, and we appreciate you bringing it to our attention.
Our sleepsuit bags are not designed to have the zips run all the way down to the base like a traditional Sleeping bag. As the sleepsuit is designed to convert to legs with space for their little feet, the length of the zip on the bottom-half of the bag is shorter than the traditional sleeping bags to accommodate the conversion.
In any event, your feedback is important to us, and it has been referred to our Product Development Team for their attention.

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.
