Baby sleeping bag routines feel easier when bedtime is simple, comfortable, and easy to repeat. This 1.5 TOG design brings together gentle warmth, a breathable sleeveless shape, and a practical bottom-opening zip for everyday sleep from 3 to 24 months.
Made for mild to cool rooms, this wearable sleep bag is designed to stay on through the night without extra loose layers to manage. The soft cotton and polyester blend has a smooth finish, while the vest-style shape helps keep the feel light and easy for everyday use.
Some sleep essentials are all about keeping the routine steady. This one is designed to do just that. The 1.5 TOG rating offers balanced warmth for rooms between 10°C and 25°C, and the sleeveless cut supports airflow so the sleep setup feels lighter and less bulky.

The bottom-opening design also helps with overnight changes, so you can handle quick nappy changes without fully removing the bag. It is the kind of detail that makes evenings feel smoother and middle-of-the-night moments a little simpler.
