The Ayacucho Women's Lamu dress is made of natural material and has a supple drape. The dress is made from viscose produced from bamboo, which stays fresh for longer than polyester. The dress is made of cotton with the BCI mark and feels comfortable on your skin. The Better Cotton Initiative (BCI) is a partnership between development organisations that aims to make the cultivation of cotton more sustainable. The fabric is quick drying and insect repellent. The dress also has a UPF of 50+ to provide protection from the sun.
