I stress less knowing my little one is warm overnight as our house temp drops largely during winter !
- Hilda van R.Verified Buyer5/13/25ReviewingLong Sleeve Romper 1.0 TOG DaisiesRated 5 out of 5 starsThe best quality!
You really can't beat ergopouch quality. Wash after wash doesn't affect them unlike cheaper brands. The natural materials and finish are just *perfect*. Plus the fit is just right and, my personal favourite, is they have removable mittens and feetsies even at this size! Thank you legends!

These onesies are made of a nice thick quality fabric with really cute designs. I can tell that my baby is a lot warmer in these 1.0 tog rated onesies - perfect for winter as baby spends a lot of time crawling on the floor.
