Cool Blue Sleep Sack 1.0

Introducing the Cool Blue Sleep Sack 1.0. This is our slightly heavier TOG option which is perfect for cooler nights. 

Still made from the same breathable yet cozy Bamboo. Our sleep sack has a double zipper feature. 

Sizes: 0-6m (28 1/3 Inches), 6-18m (34 5/8 Inches). No need to size up!

TOG rating – aka Thermal Overall Grade – measures coziness. The higher the TOG, the toastier the sack, while a lower rating = lighter material. Opt for a lighter TOG in hot months, and heavier in cold.
