HALO SleepSack Wearable Blanket The HALO SleepSack Wearable Blanket is the one blanket available on the market this customized to fit a range of sizes to verify safety for all infants. I design is making consumers and vendors alike rethink the idea of a baby blanket. The SleepSack is the safest, yet softest blanket at the makret. It’s made of flame resistant micro-fleece. The SleepSack from HALO is sleeveless to reduce the risk of baby rebreathing into the sleeve. It reduces the risk of overheating and is easy to slip on to a sleeping child. The Sack design means that baby will never kick a blanket off or, even worse, up over his mouth and nose causing the airflow to be disrupted. An inverted zipper allows the parent to change the diaper with ease and also prevents the child from scratching his chin and even unzipping the SleepSack. HALO works hard to prevent SIDS and with the SleepSack they’ve made tremendous strides. With each and every SleepSack sale HALO donates a portion of the sale toward SIDS medical research, education and circle of relatives services and products.
