Experience ultimate performance and versatility with the TUO Kinetic 150 Zip-Off Bottom. Crafted from a lightweight 150g blend of 18.5-micron merino wool core-spun around nylon, this base layer excels in natural odor-resistance, moisture-wicking, durability, and elasticity. Full-length zippers and an above-the-boot cut allow for easy removal without taking off your boots or pants. The covered elastic waistband and flatlock seam construction ensure next-to-skin comfort while a functional fly adds to the convenience.
