The ergoPouch Cocoon Swaddle Bag 2.5 TOG is a zip-up swaddle bag that gives your newborn that snug, wrapped feeling without any of the folding and tucking of a traditional swaddle blanket. Designed to be easy to use and difficult to escape from, it holds baby securely from day one — so you can settle them for sleep with confidence, even in the early bleary-eyed weeks.
Because it's TOG-rated for warmth, the 2.5 TOG version is made for cooler rooms and can be used on its own in room temperatures between 17–23°C, with no need for loose blankets in the bassinet or cot. It's made from soft, breathable, GOTS-certified organic cotton that's gentle on delicate newborn skin, and the super-stretchy fabric moves with your baby while leaving room for growth spurts.
How it works
- Arms-in to arms-out: Arm poppers let you switch from a snug arms-in swaddle to an arms-out sleeping bag, so the same garment can adapt as your baby changes.
- Startle reflex support: The snug fit is designed to restrict the startle reflex while still allowing movement for healthy growth, giving a feeling of closeness and comfort that mimics the womb.
- Lower-TOG chest panel: The chest area is rated at 1.0 TOG to help avoid overheating and allow full chest expansion for comfortable breathing.
- Bell-shaped bottom: The roomy lower shape allows the hips and legs to move freely, supporting healthy hip and joint development.
- Two-way zipper: Opens from the bottom for quick, fuss-free night-time nappy changes, and the zip enclosure is designed to protect your baby's delicate skin.
Choosing your TOG and layers
TOG is a measure of warmth: the higher the rating, the warmer the garment. At 2.5 TOG, this Cocoon suits cooler room temperatures of 17–23°C. You can add layers underneath as needed, and each swaddle bag comes with a free room thermometer and a "what to wear" guide to help you dress your baby appropriately for the temperature. Room conditions, base layers and your individual baby all play a part, so use the guide alongside your own judgement.
Best for
The ergoPouch Cocoon Swaddle Bag 2.5 TOG is a great option for parents who:
- Want the calming, contained feeling of a swaddle without complicated wrapping
- Are dressing a newborn or young baby for a cooler room (17–23°C)
- Prefer a zip-up design with easy two-way access for nappy changes
- Like the flexibility of switching between arms-in and arms-out as baby grows
It may not be the best fit if you're dressing baby for a warmer room, where a lower-TOG option would be more suitable.
Care
Machine wash on a gentle cold cycle and low tumble dry. It can be ironed on a moderately hot setting and is dry-cleanable.
Disclaimer
Any arms-in swaddle has an ability-based stopping point. Once your baby shows signs of trying to roll, switch to the arms-out configuration using the arm poppers and follow the product instructions. Always place baby on their back to sleep on a firm, flat surface, and use the included room thermometer and layering guide to help judge warmth. This product is made from organic cotton and is not treated with chemical fire retardants; the relevant fire label applies according to AS/NZS 1249:2014.
