FlyCoco is a red 3D contoured sleep mask designed to block light for sleep and rest, with a 99% light-blocking claim and deep eye contours.
Ambient light can make it harder to settle down for sleep or a nap, whether you are at home or away from your usual sleeping space. FlyCoco is made for blocking light during sleep, daytime rest, and meditation. Its contoured shape is designed to cover the eye area while leaving room around the lashes, and the adjustable strap lets you set the fit for different head sizes.
Yes. Deepened eye-socket grooves create space over the eyes, including for long eyelashes and lash extensions. An ergonomic arc shapes the mask around the eye area, and the design is intended to avoid pressure on the eyes. Thick memory foam forms the soft face-contact layer.
The strap adjusts to fit head circumferences from 46–67.5 cm (18.11–26.57 in). It is designed for women and men, and can be tightened or loosened to help keep the mask in place during sleep.
Hand-wash FlyCoco with water below 40℃ /104℉, then leave it to dry naturally before use. Gently hand-wash it before its first use as well; odors can occur during production and transportation. The mask can be used for sleeping, napping, or meditation at home, in an office, or while travelling.
