What is a TOG?

What is a TOG?

TOG stands for Thermal Overall Grade and is a unit of measurement for insulation and warmth of sleepwear and bedding. The lower the TOG rating, the lighter the fabric; the higher the rating, the more padded and insulated it is.

Size Guide

Cocoon Swaddle Bag

Please use your child's weight to find the most appropriate and safe size for them. To comply with safety requirements, our Cocoon Swaddle Bags have a firm fit around the neck, shoulder and chest area to prevent your little one from slipping inside. You should be able to put 2 fingers inside the neck opening for the correct fit. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.

Butterfly Cardi

The Butterfly Cardi is designed to be a firm fit, to mimic the enclosed feel of a swaddle. The firmness can also be adjusted using the press-studs according to how strong your child's startle reflex is. Choose the tighter fit for a strong reflex, and the looser fit for older babies who have lost their startle reflex.

Best For

Cocoon Swaddle Bags are best for newborn sleepers who prefer to be swaddled

For newborns and babies either swaddled, or arms-out sleeping once rolling.


All babies are wonderfully different, and just like adults, have different sleeping styles. The Cocoon Sleep Set is an all-in-one solution that gives your baby three different sleep-style options to choose from: Arms-in, Arms-out, or Hands-up swaddling.

Whichever your baby’s preference, all three swaddle configurations are TOG-rated for warmth, and designed to keep your precious newborn safe and comfortable during sleep without the need for loose blankets.

The Cocoon Sleep Set contains two of our most popular newborn sleepwear products. The award-winning 1.0 TOG Cocoon Swaddle Bag is a TOG-rated zip-up swaddle that is easy to use, and difficult to escape from. With the ability for baby to sleep swaddled with arms in for babies with high startle reflex, or alternatively arms-out for babies with low startle reflex, the flexibility of the Cocoon Swaddle Bag is a sleep-saviour for many parents.

The Butterfly Cardi is designed to be worn over your baby’s swaddle or sleeping bag, and has two functions. It can be used as a hands-up sleeping option over the Cocoon Swaddle Bag or an arms-out sleeping bag, or as a transitional tool to help baby transition from swaddled to arms-out sleeping once they show signs of rolling. Babies who love the Butterfly Cardi usually have a lower startle reflex than those who like to be swaddled.

Both products in the 1.0 TOG Cocoon Sleep Set are made with our signature GOTS-certified organic cotton, and designed for the specific sleep needs and safety of newborns – 6 months old. Being TOG-rated for warmth, the 1.0 TOG Cocoon Sleep Set can be used for sleep in room temperatures between 21-24°C / 70-75°F without the need for blankets in the sleep environment.

How To Use

For hands-up sleeping
1. Dress your baby in a Cocoon Swaddle Bag with the arm studs open, or appropriately sized arms-out sleeping bag.
2. Lay your baby on top of the Butterfly Cardi, and contain their hands in the foldover arm pockets.
3. Do up the studs according to the strength of their startle reflex (tighter, if strong reflex. Looser, if weak reflex).
4. Their hands should be up near their face when lying on their back.
5. To transition to arms-out sleeping once showing signs of rolling, release arms fully from the foldover pockets (see below).

Always put baby down to sleep on their back, in a safe-sleep environment.

For transitioning out of a swaddle
We recommend transitioning over a 10 day period. This should commence when your baby first shows signs of wanting to roll (not after they start rolling) for their safety.

DAY 1 - 3
Dress your baby in the Butterfly Cardi over their sleeping bag or Cocoon Swaddle Bag with their arms contained within the fold-over arm pockets for all their sleeps (day & night).

Use the press studs to adjust the firmness of the Cardi around the torso. If your baby has a strong startle reflex, start with a tight fit. If your baby has a low startle reflex, you can start with the looser fit.

DAY 4 - 7
After your little one is familiar with their new sleepwear addition, you can now take one arm out of the fold-over pocket for all their sleeps.

DAY 8 - 10
In this next stage, you can take their remaining arm out of the other pocket for all their sleeps. On the final day, remove the Cardi altogether. Your baby is now sleeping, arms-out. Hooray!
