    Mason's High-Altitude Kit - Mason Matherly

    The gear I trust above the clouds, from Kilimanjaro and Mont Blanc to my Aconcagua expedition this December. Warm layers, reliable shells, and the essentials that keep you moving when the air gets thin and the temps drop. Built for the Seven Summits, useful for any big peak.
