I just received my hoodie, I love it so much, as an autistic adult with severe anxiety and get sensory overload very easily, this is a life saver. It instantly relaxes me. It is a perfect weight and the weight in the hood is really nice. Also it is very discreet, no one else would know what this is, which is a problem I have with most other compression or weighted items to wear. It just looks like a thick sweatshirt. The fabric is soft and I would equate it to maybe a thick knit both inside and outside. So it wouldn't be super hot in the fall or spring. The only thing I don't love is cuffs kind of bother me and since it's a little small it cuffs my wrist instead of my hands so that kind of bothers me. I am about 6 feet tall and wear usually a size large or extra large, this juuussstttt fits me. I would have gotten one size bigger if I could of. It's a little tight and the sleeves are short. So as a slightly above average sized adult in height who is fairly slender to medium sized with a small chest, I don't see wear that leaves anyone bigger than me. Which there are plenty of people who are, so I would suggest increasing the sizes.
