The Mons Royale Approach Merino Gridlock Jacket keeps us light and toasty when chasing backcountry powder. Equipped with odor-fighting merino fibers and a balanced construction that keeps heat high and weight low, this midlayer excels on our multi-day missions. The mesh panels boost airflow, so we don't overheat on the climb, while the woolly blend traps heat even when wet, ensuring we stay warm through transitions.
