The impossible just became possible. Say hello to HALO SleepSack Swaddle Ideal Temp, the ONLY swaddle that helps regulate your baby’s temperature. Featuring IntelliThread technology, our innovative smart textile for newborns absorbs heat, stores it, and then releases it back to your baby, maintaining an ideal temperature and avoiding heat spikes (that often lead to wakeups). Yes, really. Bonus points: IntelliThread fibers are embedded in the fabric, so they won’t ever fade or wash out!
