Made for everyday bedtime routines
1.0 TOG thermal rating.

Choose the right fit
Available in NB–6M, 6–18M and 18–36M. Age labels are a starting point: check the manufacturer’s size guidance and make sure the neck and arm openings fit securely so your baby cannot slip inside. Choose warmth for the actual room temperature and clothing layers, rather than the season alone.
For families using or renting SNOO
This is a regular sleep bag for an appropriate crib sleep setup. It is not a SNOO Sack, does not attach to SNOO and must not replace the required SNOO safety system. Follow Happiest Baby’s instructions while using SNOO.
Delivery and purchase details
One sleep sack per purchase. A one-time purchase, separate from your SNOO rental. Fulfilled by Silkberry Baby from Canada; typically dispatched within one business day. Delivery time varies by address. Available shipping charges are shown at checkout, and this item may arrive separately from your rental.
Common questions
Does 1.0 TOG work for every room?
No. TOG describes insulation, not a guarantee of comfort in every temperature. Follow the product’s dressing guidance and avoid overheating.
