The complete cold-weather chart.
Seven temperature bands, three weather conditions, and both Fahrenheit and Celsius—designed for one landscape page.
Three useful layers
Wick. Warm. Shield.
A base layer manages sweat. A mid-layer retains warmth. An outer layer blocks wind and precipitation. You may not need all three, but thinking in roles makes it easier to adjust.
Carry a layer when a long route, exposed terrain, or changing weather could leave you colder than expected.
