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.

- Charelle B.Verified Reviewer3/10/26ReviewingSleep Sack 3.5 TOG Sleeved DragonfliesRated 3 out of 5 starsSleeves too short
We have a couple of these sleep sacks that were gifted to us for Christmas and love how warm they have keep my baby during this winter in a house without great heat. However the sleeves are just too short, so his hands are always popping out of the hand covers and get super cold unfortunately. I don’t know if my son has long arms relative to other babies (he seems pretty proportional to me, he’s in the 60% for height) but the sleeves have been too short the entire time we’ve had these sleep sacks (from 5m until now 8months).

My baby is 14 months old, I bought the TOG 3.5 size for 2-4 year olds and it's been great on these days when the temperature drops in the morning; she stays safe, warm and comfortable.
