Unnivoll Baby Sleeping Bag 1.0 Tog for 18-36 Months – Wearable Blanket
Product description
What this is and what it’s for
The Unnivoll Baby Sleeping Bag 1.0 Tog is a wearable blanket designed for babies and toddlers aged 18–36 months. Made from 100% cotton with a fluffy polyester filling, it aims to keep your little one warm and cosy without the risk of loose blankets. The 1.0 tog rating places it in the lower end of the warmth spectrum, suitable for room temperatures around 20–24°C. It’s a practical alternative to traditional wraps or blankets, providing constant coverage while allowing free arm movement.

How it’s put together (quality at a glance)
The sleeping bag features a quilted design to distribute the filling evenly, reducing lumps and ensuring durability with everyday use. A preshrinking process helps minimise later shrinkage to under 2% after machine washing and low-temperature drying (below 30°C). The fabric is soft and gentle on delicate baby skin, which matters for longer wear.

What stands out


Two features worth noting are the 2-way zipper and the zipper protector. The full-length two-way zip allows easier night-time nappy changes without fully waking your child, while the protective top stops the zipper from chafing the chin. The sleeveless cut promotes airflow and reduces overheating, yet the overall fit remains roomy enough for kicking and growth.

Who it’s for
This sleep sack is marketed as suitable for newborns through toddlers who weigh roughly 10–34 pounds, depending on size (S, M, L, XL). It’s unisex, so it works for both boys and girls. If you’re looking for a breathable option that covers arms yet leaves room to move, this could be a good match.

When it makes sense to buy
- You want a simple, all-in-one sleeping solution that reduces the risk of blankets covering a face.
- Your baby tends to wriggle and kick, risking loose blankets but you still want warmth without overheating.
- You’re shopping for a practical, durable option for daily use that’s easy to care for.



When it might not be the best choice
- If your baby sleeps in cooler or warmer environments outside the 20–24°C range, you might need a warmer or lighter option.
- If you require a model with additional features (e.g., built-in foot coverings or different weightings), this design remains fairly basic.

What to check before buying
- Confirm the size you need: S (0–6 months), M (6–12 months), L (12–18 months), XL (18–36 months). Weigh your child against these ranges.
- Look at room temperature needs: 20–24°C is ideal for 1.0 tog, in cooler rooms you may require extra layers.
- Consider washing routines: preshrunk with care guidelines (machine wash, low temp drying). Do you have a suitable washer-dryer setup?
Practical usage and alternatives


In use, imagine a night when the room is comfortably warm but not hot, your child stays covered and can move arms freely for playtime after a nap. Compared with loose blankets or sleep sacks with heavier tog ratings, this option emphasises a balance of warmth and breathability. If you live in a notably cooler climate or want to transition through multiple seasons, you’ll likely compare it to higher tog options or separate layers for flexibility.
FAQ (based on available details)
- Is it suitable for 18–36 months? Yes, the XL size targets that range and more, with a roomy fit for growth.
- How easy is it to change nappies at night? The 2-way zipper enables changes without fully undressing the baby.
- How durable is it after washing? Preshrunk, expected shrinkage under 2% with machine wash and low-temperature drying.
Is it worth it?
Worth considering if you prioritise a practical, skin-friendly sleep solution that stays on while your child moves and grows. It isn’t the only option for seasons beyond a 20–24°C room, and if you expect to use it heavily in cooler months, you may want to pair it with additional layering.
