Socks built for better sleep. The Earth Wardrobe Alpaca Bed Sock is a well-made sleep essential from a brand built around the belief that sustainable fashion should never compromise on quality, comfort, or purpose. Made from alpaca wool, it brings a considered, sustainable sensibility to a classic bed sock silhouette — naturally warm, exceptionally soft, and built to keep feet comfortable throughout the night without the synthetic materials or environmental cost of conventional alternatives.Alpaca wool is one of the finest natural fibres available for sleepwear — softer than merino, naturally hypoallergenic, and temperature-regulating in a way that synthetic materials simply cannot replicate. It keeps feet warm when the temperature drops without overheating, making it the ideal fibre for a bed sock that works across all seasons. A genuinely luxurious upgrade to the everyday sleep routine, and a reliable, well-made sustainable essential from a brand that takes organic fashion seriously. Machine washable for everyday ease.
