- Shreya h.Verified Buyer9/2/26ReviewingLong Sleeve Romper 1.0 TOG Oatmeal MarleRated 5 out of 5 starsSo soft and high quality
Love the material!
- Mim Z.Verified Buyer8/20/26ReviewingLong Sleeve Romper 1.0 TOG DragonfliesRated 5 out of 5 starsGreat layer for winter
I love that my little one can be warmer in winter. However, they run quite big and i do wish they did 2x pieces for size 1 rather than a onesie, it’s much easier with a wiggly toddler with the two pieces
- Stacey P.Verified Buyer8/10/26ReviewingLong Sleeve Layer 1.0 TOG RoseRated 5 out of 5 starsAlways a winner and great paired with the cocoon swaddle
First started using Ergopouch onesie and sleep suits with our first born when he was 3 months old. This time around we started using the cocoon swaddle.and tog rated onesies from day 1 with our daughter. So much easier to snuggle up and maintain a good body temp.ivernight when layered. A lot easier to navigate in the night for nappy changes and having to do a full.swaddle wrap everytime. Highly recommend the tog rated onesies and the sleep cocoon. Make the perfect pair to keep a newborn snug.anf feeling secure.
