I've been using the bonnet a few nights now and it’s just what I was looking for. It feels lovely and has a good amount of room for my (straight, shoulder-length) hair. It stays on pretty well – I’ve only woken up once to find that it had worked its way off. It helps my hair to retain the freshly-washed look after being slept on, which is something I struggle with due to my hair being so fine. I’m really interested to see what it’ll do for the condition of my hair with long-term use.
