Our Sleep Sack is a baby and toddler sleeping bag designed for arms-out sleepers (usually from around 3 months of age). The Sleep Sack has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'first sleep sack' after the swaddling phase is over. Please use your child's weight and height to find the most appropriate and safe size for them. A sleep sack should be well fitted around the neck and the armholes to avoid your baby slipping through. It should also be bell shaped in the bottom to allow for easy leg movement. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.

- Roma S. T.Verified Buyer5/26/26ReviewingSleep Sack 2.5 TOG Sleeved WillowRated 1 out of 5 starsDisappointed with Warmth of the 2.5 TOG Sleep Bag
I purchased the Ergopouch 2.5 TOG Sleeved Willow sleep bag for my son, but unfortunately it has not performed as expected. We have used sleep bags since his birth, including other Ergopouch and Love To Dream products, and this one feels noticeably colder on the inside despite following the recommended TOG dressing guide.
Since using it, our baby has been waking more frequently overnight, seemingly due to not staying warm enough. I wanted to raise this concern as it relates to a toddler product and see whether anything can be done to resolve the issue.
