Cocoon Swaddle Bag, 1.0 Tog
7.3/10 overall£35.00
A zip-up swaddle bag with a wing design that swaddles the arms while leaving the hips and legs free to move naturally.
The Cocoon swaddle bag combines two things some swaddles handle separately: secure arm swaddling via a wrap-around wing design, and a roomy, hip-healthy bottom half that lets legs move and bend naturally into the recommended 'frog' position, in line with hip dysplasia prevention guidance. It's made from a TOG-rated, breathable bamboo-cotton blend, which matters for temperature safety — the NHS Safe Sleep guidance is clear that overheating is a risk factor, and TOG-rated sleepwear removes the guesswork of how many extra layers to add.
Against Love To Dream's Swaddle UP, both prioritise arm freedom in slightly different ways: Swaddle UP's arms-up design lets a baby bring hands to their face to self-soothe, while the Cocoon's wing wrap gives a snugger, more traditional swaddle feel some newborns settle into more easily in the earliest weeks. Many parents move from a snugger 1.0 Tog wrap style toward an arms-up design as the startle reflex fades.
What we liked
- Roomy, hip-healthy bottom half alongside secure arm swaddling
- Breathable TOG-rated fabric removes guesswork on overheating risk
- Snug wrap style some newborns settle into more easily than arms-up designs
Where it falls short
- Snug arm design needs transitioning away from once the startle reflex fades
- Sizing needs replacing more often than adjustable swaddles as baby grows
- Zip-up design less adjustable mid-feed than a traditional swaddle blanket

How we scored it
Self-Soothe / Arms Freedom
Whether the design lets baby get a hand to their face to self-settle, versus fully restricting arm movement.
Snug arms-in design is soothing for many newborns but doesn't allow hands-to-face self-settling like arms-up styles.
Safety & Hip-Healthy Fit
Room for natural hip and leg movement and overall adherence to safe-sleep guidance.
Roomy, hip-healthy bottom half well aligned with hip dysplasia prevention guidance.
Value & Longevity
How many months of use you realistically get before baby outgrows or rolls out of it.
Good quality for the price, though sized fairly tightly to the newborn weeks.
