I have tried many different sleep masks, and I think this is my favorite so far.  I used to sleep with one made of silk/satin with a velcro strap, but it was stuffed with lilac.  Given that I have allergies, and my eyes were really bothering me, my eye doctor suggested I do away with the lilac stuffed mask and try something else.  I gave this Lewis & Clark a try (ordering the BLACK, based on other recommendations to avoid Navy), and I'm so glad I did.

The buckle/slide adjustment, rather than velcro, is easy to use and should actually provide for a longer life of the mask, since elastic stretches over time.  Velcro adjustments have a limited span for closing up the gap when the elastic stretches out. This slide buckle will allow you to keep tightening up the elastic as needed.  I have a larger than average head for a lady, and some of the velcro masks simply do not allow enough strap for me without leaving the whole thing just too tight.  This mask has plenty of  strap length for me.

One other reviewer mentioned that the buckle is uncomfortable sleeping on the right side.  If you place the elastic on your ear, that is true. I found that by placing the elastic just above/behind my ear I was not uncomfortable. If they would simply move that buckle a little more toward the back and get it off the ear entirely, it would be better, but then you would lose some of the adjustment range that it currently offers.

The eye pillows on this mask are quite full, and absolutely no light leaks through for me.  The main body of the mask is padded, which makes my eyelids stay firmly closed all night (I have a problem with one eye lid being partially open when I sleep, which is why I need a mask in the first place.)  So, eyelid problem solved.  Light blocked, comfortable mask.  If the buckle were slightly relocated, i would give this one a 5 star rating.

Other pluses with this mask:  it is hand washable (the silk ones are not), it's an excellent price for a padded mask with an adjustable strap and really effective eye pillows.
