The Longhaul Shop Pant: Not Your Father's Wool. Our proprietary merino blend is the result of over a year of fabric testing and prototyping; designed to maximize comfort, durability, and style. We worked with custom textile fabricators to dial in our proprietary blend to maximize comfort, durability, and style. The Longhauls are made from a mix of 75% fine Australian merino wool, 21% viscose bamboo, and 4% elastane. Tapered legs and an athletic fit give the Longhaul a modern look and minimizes extra fabric to avoid snags and flapping in the breeze when you're working hard. Launched on Kickstarter after almost 2 years in development and now available to everyone. Upgrade your pant drawer with the Longhaul and live the full merino life.
