the best i have tried [SEP] i have tried nearly a dozen different sleep masks and this is my favorite it manages to block the light without gaping and manages to keep from pressing on my eyes without any of the annoying padding or buldging cups i have experenced on others which allows me to sleep comfortably in my sides the material has remained silky after years of use i also like the adjustable velcro strapi bought a new one recently as a back up and was disappointed to find it scented especially since i use it mainly for my migraines however with nothing to lose i put it through my washing machine on cold and air dried it after that one wash the scent was gone and does not irrtate my very sensitive skinyou cannot beat this mask for comfort and effectiveness especially for this price still give yourself enough time before needing it to throw it through the washing machine
