Cool It Boi came first, bringing the liquid silky feel best described as a colder cozy and Cooling goes one step further by providing all that plus a squishable plush interior. Made of a 400 GSM of seriously soft filling that we guarantee you've never felt before (beyond the softness of Down Alternative). It's a new level of plush filling that, when combined with the outer 180 GSM nylon and spandex blend, you'll find it hard to ever leave your bed again.
