The Neumel Natural, made with plant-based materials, retains the iconic look and feel of UGG®'s bestseller, the NEUMEL. It is woven from a durable blend of 55% cotton and 45% hemp. Hemp is a renewable resource that absorbs carbon dioxide from the atmosphere. Another material that brings UGG®'s signature comfort through the power of plants is TENCEL™, made from regenerated cellulose fibers sourced from sustainable eucalyptus farms. The naturally tapped rubber sole, handcrafted from latex, provides maximum cushioning while minimizing environmental impact as it does not require the felling of old-growth forests. - Upper: Cotton / Hemp - Lining: 17mm Tencel™ Lyocell plush * - Insole: 17mm Tencel™ Lyocell plush * - Outsole: Hevea rubber ◆ Upper - Due to plant-based dyeing, color may change with UV exposure. ◆ Rubber Sole - Made with 100% natural raw materials and handcrafted, air bubbles or streaks may be visible. - Color may change over time from when purchased (e.g., darkening). - Blooming (powdering) may occur due to the nature of the material.
