HALO SleepSack Wearable Blanket 100% Cotton review

HALO SleepSack Wearable Blanket 100% Cotton ranks first because it covers the basic need of a post-swaddle baby at a fair price and with few things to get wrong. HALO describes it as the next step after swaddles, a roomy, extra-long cotton sack that replaces loose blankets in the crib. The 0.5 TOG rating suits rooms from 68°F to 77°F, and the inverted zipper opens from the bottom so a night diaper change does not mean taking the whole sack off. HALO lists approval from the International Hip Dysplasia Institute and a zipper cover to prevent irritation. Sizes run from Small at 10 to 18 lb up to Large at 22 to 28 lb, and HALO sells a 1.5 TOG bamboo version in sizes up to 36 lb for cooler rooms at $44.99. The trade-off is that this sack has no wings or arm coverage, so babies who still want a snug feel may need a transition product first. We compared documented features and published prices.

Who it is for
