Who Should Buy This?

New parents struggling with inconsistent sleep schedules will find this sleep sack invaluable. It's designed for babies 8–13 pounds who benefit from swaddling but also need their arms free to self-soothe. If your baby wakes frequently from the startle reflex or fights traditional swaddling, this arms-up design offers the perfect middle ground between freedom and security.

Buying Tip

Pairs perfectly with breathable crib sheets and a white noise machine for optimal sleep conditions. Consider buying two so you always have a clean one available while the other is in the wash. Check your room temperature against the TOG guide—this 1.0 TOG version is warm enough for mild climates but may need layering in colder environments.
