says it is adjustable [SEP] this bonnet is smarter than me it says it is adjustable i gave up trying to figure that out it is very large and in no way makes it through night on my head i am still giving it stars though because if you can figure that adjusting things i am sure it is great but it does also come with satin scrunchies that are the absolute best for sleeping i love them they are great for sleeping and keeping your hair looking great i pull my hair back or up every night but rubber bands are really terrible for it because they will get tangled up so these satin scrunches really do not do that they are much smoother and gentler on your hair i am sure i will keep trying to adjust the bonnet i do like wearing them when i use oils in my hair or if i go to bed with wet hair to protect my pillow and keep my head warm if i cannot figure it out well at least i got two awesome scrunchies for sleeping
