The Ayacucho Men's Sechura Eco Crew Sweater is a great basic top for casual outdoor activities. Tencel is as soft as silk but as strong as polyester. Tencel dries quickly, is naturally antibacterial and disperses moisture and perspiration – it will keep your skin cool and dry. This sweater 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.
