Manta PRO Sleep Mask
The Manta PRO is a contoured blackout mask whose C-shaped eye cups slide along the strap to match your eye spacing, so the seal lands on cheekbone and nose bridge with nothing touching the eyelids. It suits side sleepers, shift workers and long-haul travellers who have given up on flat masks. Its trade-off is bulk and a premium position; the MZOO does most of the same job for less.
