Review title is says it's adjustable? [SEP] this bonnet is smarter than me.  it says it's adjustable - i gave up trying to figure that out.  it's very large and in no way makes it through night on my head.  i'm still giving it 4 stars though because if you can figure that adjusting things, i'm sure it's great.  but it does also come with 2 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 don't do that, they are much smoother and gentler on your hair.  i'm sure i'll 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 can't figure it out, well at least i got two awesome scrunchies for sleeping.
