side by side comparison of three sleep masks earth theraputics is no longer my favorite [SEP] this is a side by side comparison of three earth therapeutics mind body therapy sleep mask cotton silk i have used the earth therapeutics soft mask for five years and the the nidra and bedtime bliss masks for the last several months all have their advantages and disadvantages my favorite is now the nidra mask but it has an important flawi sleep from after midnight until and my bedroom is bright therefore i need a mask that will stay on for seven or eight hours if it shifts when i move during the night it will not be covering my eyes when the sun comes upalthough i used it for several years the earth therapeutics mask does the worst job of staying in place all night i think this is because it does not have as much shape or structure as the other two masks also it presses on your eyes making it a bit less comfortable than the other two masks i no longer use this maskthe nidra mask does the best job of staying in place it is also slightly larger than the bedtime bliss mask and feels a bit more comfortable however the nidra has a flaw i have stopped using the earth therapeutics mask the bedtime bliss and nidra are very similar but the nidra fits me better and stays in place longer if you have a large head like me the nidra mask will be tight if you have a small or narrow face try bedtime bliss
