Sleep & Wellness

Sleep products are usually sold on vibe — soft, dark, quiet — without much detail on what they're actually made of. The mask is often polyester satin marketed as silk. The earplugs are often PVC. The blue-light glasses often filter nothing measurable.

Mulberry silk for the mask, food-grade silicone for the earplugs, lenses with their actual transmission spectrum published for the glasses. Three things you put against your face for eight hours — worth knowing what they are.
