A hat works harder than any other piece of kit per gram of weight. In summer it's your first line of defence against heat and UV — a wide-brimmed sun hat or a technical trail cap can make a full day in exposed terrain genuinely comfortable. In colder months a warm beanie or insulated hat retains the heat your body works hard to generate. The caps and hats at Mountex cover the full seasonal range, sourced from outdoor brands that treat headwear as seriously as any other technical piece. Small item, significant impact.
