Review (1/5): Not for me!
This cap is vinyl and had a film that rinsed off while showering with it. It had a bad taste, so I kept rinsing my mouth and body after I had already showered. I've had similar experiences with cheap drugstore caps. I prefer the nylon caps like Fashionista which are a bit more expensive but are much roomier and have no film or odor. They keep your hair dry as well because they are lined with waterproof nylon.
