Choose hiking clothing based on the dominant weather challenge you'll face:
Cold weather (below 10°C):
Thermal base layers (midweight to heavyweight merino or synthetic)
Insulating mid layers (fleece or synthetic insulation)
Windproof outer layer to prevent heat loss
Moisture-wicking fabrics to prevent damp cold from sweat
Extended coverage (high collars, long sleeves, full-length trousers)
Rain and wet conditions:
Waterproof shells with taped seams and waterproof ratings above 10,000mm
Water-resistant hiking trousers or waterproof overtrousers
Breathable membranes to manage internal moisture
Quick-drying base layers and mid layers underneath
Adjustable hoods, cuffs, and hems for weather sealing
Hot weather (above 20°C):
Lightweight, highly breathable fabrics with maximum airflow
Moisture-wicking base layers or technical t-shirts
UPF sun protection in fabrics for exposed skin coverage
Light colors to reflect heat
Ventilation features (mesh panels, pit zips) in outer layers
Quick-drying materials to handle sweat
Snow and winter conditions:
Layering system: thermal base + insulated mid + waterproof shell
Windproof outer layers to prevent wind chill
Water-resistant or waterproof trousers to shed snow
