Hooga Dual Sided Weighted Blankets offer a cool side, and a warm side, making it the perfect blanket for any occassion, season, or body type. One side of the removable, washable cover features our silky, smooth Bamboo material which keeps you cool but comfortable while the other side features our luxurious, warm Minky material when you need a little extra warmth and coziness. Inside you'll find the innner weighted blanket, which is comprised of small, compact compartments housing our non-toxic, hypoallergenic glass beads which make the weighted blanket exactly what it is--weighted! The added weight from the glass beads tends to elicit feelings of calm, relaxation and ease. Using a weighted blanket is often compared to being swaddled as an infant, or perhaps receiving a big hug from a loved one. The general rule of thumb for choosing a weighted blanket weight is roughly 10% of the user's body weight. So, if a person is 200lbs, they may choose to go with a 20lb weighted blanket. At the end of the day, though, it comes down to personal preference and also how you intend to use the blanket.
