SleepSloth is a 3D contoured sleep mask designed to help block light for rest, with deep eye cups that leave room to blink naturally.
Daylight, cabin lighting, and other ambient light can make it harder to settle down for a rest break. SleepSloth is designed for nighttime sleep as well as daytime naps and recovery after a night shift. Its portable format also suits plane travel and meditation, while the shaped eye area and adjustable strap are intended to support comfortable wear across different sleeping positions.
Yes. The deep, contoured eye cups let you blink without the mask touching your eyelids or eyelashes, and provide space for eye makeup. Their shape is designed to reduce pressure on sensitive eyes during extended wear. The mask’s contours fit closely around the eyes and nose to help limit light entering at those areas.
Its soft, low-rebound memory foam gently cushions the face and helps reduce pressure points for side, back, and stomach sleepers. The construction is lightweight and breathable, and the slim elastic strap is designed to remain comfortable without pulling hair, snagging, or causing discomfort behind the ears.
The elastic strap adjusts from 15.8 to 27.6 inches (40.1 to 70.1 cm) to provide a secure fit for most head sizes. Use the mask for overnight sleep, afternoon naps, plane travel, meditation, or rest after shift work. Its light weight makes it suitable to take along when you need a sleep mask away from home.
SleepSloth is suited to people who want a contoured eye cover for different sleep positions and settings, including side sleepers, travelers, and shift workers. Its deep eye cups, cushioned memory foam, and adjustable strap make it a practical choice for rest when reducing exposure to light matters.
