WHY BAMBOO?

HYPOALLERGENIC

Bamboo fibers are naturally smoother and rounder with no sharp spurs to irritate skin. It also requires way less dye compared to conventional types of fabric. Making it ideal for those who experience allergic reactions or with skin sensitivities. 

MOISTURE WICKING

Bamboo fabric is extremely breathable. A cross-section of its fibers reveals various micro-holes allowing bamboo cloth to have a superior absorption. Its fibers absorb 40% more than any other type of fiber. Absorbs and evaporates moisture faster pulling it and driving it away from your skin.

SUPER SILKY SOFT

Bamboo fabric is extremely durable yet still has a natural soft and silky feel to the touch that you can easily compare with cashmere and silk. Bamboo fibers are smooth and round and contain a natural ingredient called pectin that helps enhance its soft texture. The fabric drapes elegantly without wrinkling.

UV PROTECTION

Scientifically proven to possess sun blocking characteristics. Shield your skin from the harmful UV rays in comfort. Considered a UV protective as it cuts 98% of harmful UV rays. An Australian study found that bamboo shields the wearer from sun up to 60% more effectively than cotton.

POWERFULLY INSULATING

Comfort in any season. Natural fiber insulation naturally regulates your body’s temperature. A recent study by theInternational Journal of Thermal Sciencerevealed that fabrics containing a higher percentage of bamboo fibers provided an increased level of thermal regulation. Cool in summer and warm in winter. How great is that?!
