Think in systems: breathable merino next to skin, lofty mid-layers trapping heat, and a shell blocking wind that slices through river valleys. Avoid cotton, manage sweat, and size outerwear for movement. Comfort equals patience, which directly increases your chances of witnessing complex auroral structures.
Choose insulated boots rated well below your expected lows, add wool socks, and carry spare pairs. Chemical warmers tucked near toes and kidneys help circulation. Simple hacks like seated pads and thermos cozies prevent heat loss so the night remains inviting, not punishing.
