The Winter Cocoon Swaddle Bundle pairs a 2.5 TOG and a 3.5 TOG Cocoon Swaddle Bag at 20% off RRP. Here's a step-by-step way to layer and use both through winter.
Quick Answer
The Winter Cocoon Swaddle Bundle gives you two Cocoon Swaddle Bags — 2.5 TOG and 3.5 TOG — for USD 102.13 instead of USD 139.90, a 20% saving off RRP. Use the 2.5 TOG for typical heated winter rooms and the 3.5 TOG for colder nights or unheated spaces, adjusting your baby's base layer first. Both bags share the same secure Cocoon fit, so you can switch between them without relearning the wrap.
What the Bundle Actually Contains
The Winter Cocoon Swaddle Bundle is a two-piece set: one Cocoon Swaddle Bag 2.5 TOG and one Cocoon Swaddle Bag 3.5 TOG. Buying them together saves 20% off the combined RRP of USD 139.90, bringing the bundle to USD 102.13. That works out to roughly USD 51 per bag, which is the practical reason most parents choose the bundle over a single swaddle — you get two warmth levels for the price of about one and a half.
Why Two TOG Ratings Beat One
Winter room temperatures swing more than you'd expect. A heated nursery might sit around 20-22°C on a mild night, then drop several degrees during a cold snap or if the heating cycles off. Rather than adding blankets — which aren't recommended for swaddled babies — you change the swaddle's TOG rating. The 2.5 TOG handles the warmer end of winter, while the 3.5 TOG covers the colder end. Keeping both on hand means you're not caught out at 2am trying to improvise layers.
Choosing Between the 2.5 TOG and 3.5 TOG
Start with the 2.5 TOG if your baby's room is heated and stays reasonably stable overnight. Move to the 3.5 TOG when the room runs cold, when you're travelling somewhere without heating, or during a particularly harsh cold spell. The key checkpoint is your baby's chest and back — not their hands or feet, which often feel cooler than the core. If the chest feels hot or clammy, you've overdone it; if it feels cool, step up a TOG.
Layering Under the Swaddle
The swaddle is the outer layer, so what goes underneath matters. In most heated winter rooms, a long-sleeve bodysuit or lightweight pyjamas is enough under the 2.5 TOG. For the 3.5 TOG in a cold room, a warmer bodysuit or slightly thicker pyjamas works. Avoid piling on multiple thick layers under a high-TOG swaddle — that's the most common winter overheating mistake, and it's harder to spot than under-dressing.
Step-by-Step Winter Swaddle Routine
- Check the room temperature first: Read the nursery thermometer before choosing a swaddle. Use the 2.5 TOG for a heated room that stays mild overnight, and the 3.5 TOG for a cold or unheated room. Mistake to avoid: picking a TOG by season rather than by the actual temperature your baby sleeps in.
- Dress your baby in a base layer: Put on a long-sleeve bodysuit or lightweight pyjamas under the 2.5 TOG. For the 3.5 TOG in a cold room, use a warmer bodysuit or slightly thicker pyjamas. Checkpoint: one sensible base layer, not several thick ones.
- Swaddle arms-in for the early weeks: Lay your baby in the Cocoon Swaddle Bag and fasten it arms-in for the secure, contained fit newborns settle best with. Mistake to avoid: wrapping too loosely — a loose swaddle can ride up over the face.
- Switch TOG ratings as the weather shifts: Keep both bags within reach. Move from 2.5 TOG to 3.5 TOG when the room turns cold, and back again when it warms up. Checkpoint: the swaddle should feel snug but leave room for the chest to rise and fall freely.
- Check your baby's chest and back: Feel the chest and back — not the hands or feet — after your baby has been asleep for a while. Hot or clammy means too warm; cool means too cold. Next step: adjust the base layer before changing the swaddle, since it's the easier variable to fix.
- Stop swaddling at the first roll: Once your baby shows signs of rolling, transition out of arms-in swaddling. The Cocoon Sleep Set's arms-out option is a natural next step. Mistake to avoid: continuing arms-in swaddling after rolling begins.
Bundle Details
- Winter Cocoon Swaddle Bundle: Includes 1 x Cocoon Swaddle Bag 2.5 TOG (RRP $64.95) and 1 x Cocoon Swaddle Bag 3.5 TOG (RRP $74.95). Two warmth levels cover the full range of winter room temperatures without buying blankets or extra swaddles.
- Winter Cocoon Swaddle Bundle: Bundle price is USD 102.13, compared to USD 139.90 RRP — a 20% saving. You get both TOG ratings for less than the cost of buying them separately, which matters if you're unsure which warmth level you'll need most.
If you're weighing the bundle against a single swaddle, the two-TOG approach is the more practical winter setup — you're covered whether the heating holds or fails. Pair it with the Cocoon Sleep Set when your baby starts showing signs of rolling, so the transition to arms-out sleep is already sorted.
