The outer layer of the blanket is made of bamboo fibres, which are: Cooling, moisture-wicking and easy for the skin to breathe in. As cotton absorbs moisture and retains heat, bamboo conducts moisture away and does not retain heat nearly as much, providing a nice, cool sleeping experience. Incredibly soft due to its finer threads (compared to cotton). Bamboo's cooling and moisture-repelling abilities mean that allergenic dust mites are not attracted. Environmentally friendly, as bamboo does not require fertilizers or pesticides to grow and is therefore chemical-free. Bamboo also grows faster than any other plant in the world, which is why bamboo production does not contribute to environmentally harmful deforestation. Odor resistant as it does not retain sweat moisture and therefore does not attract micro-organisms to the same degree as cotton.
