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.

- Thea D.Verified Buyer5/8/26ReviewingSleep Sack 2.5 TOG DragonfliesRated 5 out of 5 starsWarmer than my previous 2.5tg bags from a few years ago? But I think it is a good thing :)
Great quality as usual (although some of the stitching has already come undone). Otherwise seems a lot heavier than my previous orders of the same bag 2.5tg but it’s been good on the colder nights, just the borderline warm nights if feels a little too hot. Otherwise good! Much more roomy than a few years ago too!
- Laura M.Verified Buyer5/1/26ReviewingSleep Sack 2.5 TOG DaisiesRated 5 out of 5 starsWorth it
Beautiful sleeping bag. So soft and washes well. Worth the money and gives piece of mind it's made of breathable fabric on gentle skin!

Easy to wash and dry. Material feels very soft and comfy. Easy to zip baby in and out (no poppers!). Gorgeous design too- love it.
