We’ve chosen to create our luxury line of Sheets and Duvets using only 100% organically grown bamboo. This allows for the smoothest, silkiest and most breathable fabric, and is considered our ‘superior’ line. The eco-melange line consists of a blend of bamboo and cotton threads, so you do have options if you want a blend. But the 100% bamboo line will give you the most cooling effect. They’re also more resistant to bacteria and odors, and more comforting against sensitive skin.
