Milkweed Insulated Quilted Scarf - Soft, Breathable, Comfortable Bamboo Viscose Exterior for Winter and Fall This warm and cozy milkweed-insulated scarf was designer to beat the icy winds of arctic winters. Soft, simple and pleasant to the touch, Lasclay's precisely quilted, light-as-air scarf will keep you warm even in the harshest conditions, with style. Lasclay's products offers the rare combination of high performance, durability and sustainability with its revolutionary insulation made from milkweed silk—a plant-based material warmer than down, naturally waterproof, and hypoallergenic. Featuring an easy-to-clean dry-bag interior, it's also machine washable (cold water, delicate cycle). By choosing this scarf, you support the organic farming of milkweed, which promotes biodiversity by creating much-needed habitats for monarch butterflies and other pollinators, while also capturing CO2 to reduce greenhouse gases on otherwise unused marginal land​​​​​​.
