HALO 100% Cotton 0.5 TOG Sleepsack Wearable Blanket

HALO SleepSack is an award-winning wearable blanket for safe sleep. It s also the recommended next step after SleepSack wearable blanket for a seamless transition without losing sleep. Design details include a zipper that opens from the bottom for easy diaper changes, and a roomy, extra long sack. That means it s hip healthy and you won t have to size up as quickly. 100% cotton is soft, breathable and especially gentle on baby skin. Starting in 2024, we ve removed the "Back is Best" embroidery from SleepSacks. To reduce waste, we re selling through inventory and are unable to guarantee which version you will receive.

Not 100% Cotton

It’s very, very hard for me to believe this is 100% cotton. It feels like it contains elastane. It also did not absorb water when tested. The product itself feels fairly cheaply made.
