Category: Comparisons

Compare the Spring Cocoon Swaddle 1.0 TOG and 2.5 TOG bags to find the right warmth for your baby's room temperature and season.

Quick answer

Choose the 1.0 TOG for warmer rooms (24-27°C) or the 2.5 TOG for cooler rooms (18-24°C). The bundle gives you both to handle changing spring temperatures.

Why TOG matters for safe sleep

TOG (Thermal Overall Grade) measures a swaddle's insulation. Using the right TOG prevents overheating or underheating, which are both linked to unsafe sleep. The 1.0 TOG is a lighter layer, while the 2.5 TOG provides more warmth.

When one TOG isn't enough

Spring weather can swing from cool nights to warm afternoons. A single swaddle may not cover all conditions. The Spring Cocoon Swaddle Bundle solves this by offering both TOGs in one set, saving you from buying separately.

Trade-offs at a glance

  • 1.0 TOG – lighter, for warmer rooms: Use when the nursery is 24-27°C. It's the go-to for warm spring days or heated rooms. Less insulation means less risk of overheating.
  • 2.5 TOG – warmer, for cooler rooms: Use when the nursery is 18-24°C. Ideal for cooler spring nights or air-conditioned rooms. Provides cozy warmth without extra blankets.
  • Bundle – both TOGs, one price: The Spring Cocoon Swaddle Bundle includes both 1.0 and 2.5 TOG bags at 20% off RRP. Swap between them as the weather shifts. Check the room temperature before each sleep and choose the corresponding TOG. No guessing needed.
