TOG Sleepwear Products

TOG-Rated Baby Sleepwear in Organic Cotton

Take the guesswork out of dressing your baby for sleep. Every piece here carries a TOG rating — the measure of how warm it is — so you're never wondering whether a layer is right for the room. Match the number to your nursery temperature (our TOG guide shows you how) and your baby sleeps not too hot, not too cold, but just right.

The range covers the whole night, and the whole first year:

• TOG-rated rompers (0–3 months) — the layer that goes under the sleeping bag. Most onesies aren't rated, so the base layer becomes a guess; ours print the number on the tag. Choose 0.2 TOG for warmer rooms, 1.0 TOG for cooler ones.
• Swaddle sleep sacks (0–3 months) — arms-in to arms-out, for newborns finding their sleep.
• Sleeping bags (3–12 months) — arms-out freedom as your baby grows.

All in breathable, hypoallergenic organic cotton, lab-tested to BS 16781:2018 and backed by our 100-night trial.

Not sure which TOG for tonight? Pair the range with the Goldilocks thermometer — it reads your room, predicts the overnight low, and tells you exactly what to put on. Dressing for the cold months? Our winter guide breaks it down room by room.
