The Sleep Suit Bag should be fitted around the neck and the armholes to avoid your child slipping through. In 'legs' mode, there should be enough length at the end of the suit to allow your child to move their feet freely. 2.5 TOG and 3.5 TOG Sleep Suit Bags should not be used in a 5-point harness or car seat for safety reasons.

- Catherine A.Verified BuyerReviewingSleep Suit Bag 1.0 TOG SavannahI recommend this productRated 5 out of 5 stars2 months agoFantastic mid-weight sleep suit bag
We love ergoPouch and have purchased the 1TOG sleep suit bags in the past. They are long-lasting and hardwearing, surviving daily use across multiple children. This bag has lovely smooth, soft fabric and the convertible legs are amazing when transitioning toddlers who want to roam from a bag to a suit. The 1TOG is a versatile weight for our climate (in Melbourne) during the warmer months when many nights still get cold. The short sleeves are great as can also pair with long sleeve pjs for cooler nights or short sleeve pjs for warmer ones.
This purchase was for our 3 year old who'd grown out of his previous size. He loves the ergoPouch prints and often points out the adorable characters in the various designs we already own, however this is his absolute favourite print to date. Highly recommend.

I got this for my son who’s learning to sleep under a blanket. He’s still getting use to the concept so I got him this style sleeping bag and it works a treat. I know he’s still warm if he’s out of the covers. 10/10

It works well for my 1.5yo I was trying to transition out of night nursing to independent sleeping. He runs hot and likes to move around so this worked well for him and he tolerated it decently relatively quickly.
