01 / A closer look
Look for gaps, not just coverage.
Try a mask in a lit room and pay attention to the bridge of your nose and the edges. An adjustable strap gives you more room to fine-tune the fit without overtightening it.
02 / A closer look
Flat or contoured?
A flat mask can feel simple and compact. A contoured design creates space around the eyes but adds bulk. Think about whether you prefer fabric near your eyelids or more room around them.
03 / A closer look
Read the care label.
Look at the whole material description, including the lining and strap. Choose a washing routine you will realistically follow. A delicate fabric may need more attention than you want to give it.
04 / A closer look
Test it on your pillow.
Lie in your usual position. Does the adjuster press against your head? Does the mask shift when you turn? Check the return terms before buying, because comfort is personal.
