For most resort skiing, lightweight (130-180 g/m²) is the best choice if you ski aggressively or run hot, while midweight (180-260 g/m²) is better if you run cold or spend more time sitting on lifts. Because synthetics dry so fast, you can run a lighter weight than you might with merino and still stay comfortable—your effective warmth comes from staying dry, not from fabric insulation. It's always easier to add a mid-layer for warmth than to deal with an overheating base layer.
