Natural Silk Sleep Mask
The Alaska Bear mask is the best entry-point for circadian health, using 19 momme natural mulberry silk. It provides a breathable, hypoallergenic light barrier that is far superior to synthetic polyester masks found in retail stores.
Ingredients & Purity
Made from 100% Grade 6A Mulberry Silk on both sides. Silk is naturally thermoregulating, which supports the body's core temperature drop required for deep sleep.
Scientific Evidence
Silk has a high opacity-to-weight ratio, though it may allow some light leakage at the nose bridge compared to contoured masks.
Brand Transparency
Alaska Bear is transparent about the 'momme' count (weight) of their silk, which is the primary indicator of silk quality.
Value Assessment
Unbeatable value for natural fiber. Ideal for back sleepers who don't want the bulk of a foam mask.
Why Not Alternatives?
It beats luxury brands like Slip on value while providing the same 100% mulberry silk quality. Unlike cheap 'satin' masks, this is actually breathable and doesn't cause skin irritation or overheating.
