Like a previous reviewer, I am very aware of my plastic consumption so had high hopes for this shower cap. Unfortunately, it gaped at the back when I put it on as the majority of the band is the rubber grip and there is only a small amount of adjustable elastic. Trying to slot it behind my ears was extremely uncomfortable. It is a good idea and will probably work well if you have plenty of hair but the "one size fits all" description is inaccurate.

I'm trying to cut down on plastic so a proper shower cap which is easy to use is exactly what I wanted. I hope I don't need to buy another one for years to come.
