Review (4/5): Does the Job
I purchased this mask because I work nights and have a difficult time sleeping during the day. The mask arrived in a timely manner, is made of quality materials and even has a storage pouch.
As for the functionality, it does the job of keeping daylight out, except for a few small areas around the bridge of my nose. The straps, however, were slightly bothersome and left the area behind my ears sore after wearing for a few hours. This may just be because they are new and need to be worn in a little.
Overall, it's a good mask that does the job.
