I’m glad I found this product to keep my baby warm during these below freezer temp. Baby stay in house and this onesie are perfect to keep him warm. It fits true to size

I loved how warm they are and the fabric is soft. But the zipper on the back/butt area is poor design. I don’t want my baby laying down with zippers jammed into his back. Ultimately not using these due to this.
EUergoPouch UK3 weeks agoHi Cassandra
Thank you so much for sharing your feedback. We really appreciate you taking the time to let us know about your experience with the long sleeve layer. We're sorry to hear that the zipper placement would not be ideal for your little one.
Our rompers are designed with a unique 3-way zipper that allows for easy nappy changes without having to fully undress your baby. The zipper can be adjusted to sit at the front or along the crotch area, so your baby doesn't need to lay on it while resting or playing.
We completely understand that comfort is everything, and we hope this helps you get the most out of your layer.

I have never had a bad experience with Ergopouch. The quality is amazing and they have a super smart design (full access zips and foot covers). I love the TOG ratings so I have a confident starting point to dressing my baby for the night. Orders are fast and prints are cute. Thank you!
