Designed for multiday treks and mid-output winter activities, the Rho Merino Wool Bottom offers exceptional technical performance - naturally. 150gsm Merino wool, a material known for its ability to regulate thermal comfort, resist odours and static, is soft and comfortable. A nylon core adds durability. The next-to-skin fit maximizes efficiency, layers cleanly, and elastane fibres provide stretch and mobility. The ergonomic patterning and seam placement wear comfortably and give you freedom to move.
