I’ve tried well known brands like Slip (100% silk) to more affordable options on Amazon (typical polyester & not silk) and my biggest qualm is the fit. They’re either too tight or too loose and end up somewhere in your sheets while you’re sleeping or leave a dent on your forehead. This cap is perfect! I can’t figure out how to adjust it but I have a MASSIVE head so the full width is what I want, without it being too loose to fall off. I also love the color white is offered. Most brands have the same color options like pink, beige and black (sometimes silver), and they just remind me of something my grandmother would wear, which is not a problem but I’m going more for sexy but still comfortable haha white just gives the same look a towel wrapped on your head does so it doesn’t become the focal point. It’s extremely comfortable, so much that I don’t notice it on my head at all.
