I'll start by saying that I've used other eyemasks in the past and not loved them but I absolutely love this one.
I tend to stay up really late procrastinating actually going to sleep by being on my phone, laptop, etc. I love using a mask because it forces me to actually go to sleep. This mask in particular is so squishy and pillow-like that it feels wonderful while wearing it and not constricting. I've also felt hesitant with wearing sleeping masks because of being a side sleeper, but I don't feel constricted at all with this mask.
Would definitely recommend!
