Amrules cotton sleep masks are a two-mask set designed to shade the eyes for sleep, naps, meditation, and travel, with an ergonomic nose design and adjustable elastic straps.
Bright surroundings can make it harder to settle in for sleep or a daytime rest. Amrules eye covers are made for creating a darker, more restful-feeling setting at home or while traveling, and can also be used during meditation and yoga. The two colors make it easy to keep the pair together or use them in different places.
The contoured nose area is designed to match noses of different heights and limit gaps where light can come through. Amrules positions the mask as a way to block even faint light and support uninterrupted rest. Its weighted eye-mask design adds to the sleep-focused format.
The elastic head strap is adjustable and designed to fit every head size. It is made to remain in place without slipping or falling off when you sleep on your back, side, or stomach, so the mask can suit different sleeping positions.
The set contains two cotton sleep masks: one dark blue and one dark red. Each has an elastic cotton outer layer and a fluffy velour cotton inner lining. For care, hand-wash or machine-wash in cold water on a delicate cycle, wash separately from other items, and air dry.
Amrules is suited to adults looking for a reusable eye cover for nighttime sleep, travel, naps, or quiet wellness routines. Its two cotton masks combine a contoured light-shading shape with adjustable straps and simple cold-wash care.
