Temperatures can swing wildly on any adventure. Cold mornings turn into hot days on trail. And hot days turn quickly into cold nights when the sun ducks out of sight. Adding or removing a layer in these situations is a no-brainer, but who wants to stop the ride to pull off your boots, dance out of your pants, and adjust your layers. All too often we sacrifice comfort to avoid these tedious moments. The Strata Merino Zip-off Thermal Bottom’s full-length leg zippers, over armor fit, and above the boot design allow you to quickly and easily shed or add layers without removing your boots and outer pant. 

The Strata Merino Zip-off Thermal Bottom is constructed using Nuyarn® technology, a lightweight, incredibly comfortable, and durable blend of Merino wool and nylon. By removing the twist of the yarns and drafting the fibers over a nylon core, Nuyarn® has produced a fabric with higher stretch and recovery, better moisture management, greater warmth, and increased durability than traditional Merinos. It culminates to an itch-free, moisture-wicking, and naturally odor-resistant material to take the edge off in cool conditions.
