How extreme can weather changes be in one day?

Temperature swings of 40°F (20°C) are common. You might start hiking in 70°F sunshine and face 30°F winds with sleet by afternoon. Always pack for the worst possible conditions.

Is it worth buying gear in Patagonia vs bringing it?

Bring your own base layers and boots for fit and comfort. Rent or buy shells and insulation locally if you don't own quality versions — rental shops in El Calafate and Puerto Natales stock excellent gear.

What's the biggest packing mistake people make?

Bringing cotton clothes and underestimating wind protection. Cotton kills in Patagonia's wet conditions, and inadequate wind protection makes even mild days miserable.

Do I need different gear for different parts of Patagonia?

The layering system works everywhere, but Torres del Paine and Fitz Roy areas see more severe weather than northern regions. Pack for the most challenging area on your itinerary.

How to pack for Patagonia's changing weather

Pack in layers with a waterproof shell, insulating mid-layer, and moisture-wicking base layer. Bring gear for 40°F temperature swings and sudden storms. Your outer shell and warm layers are non-negotiable — everything else can be layered up or down.

Start with your shell system. Pack a waterproof, breathable jacket and pants. Look for 3-layer Gore-Tex or similar with sealed seams. This is your defense against Patagonia's notorious wind and sudden downpours that can last hours.
Build your insulation layers. Bring a down or synthetic puffy jacket for warmth and a fleece or soft-shell for active insulation. You'll layer these under your shell when temperatures drop or winds pick up.
Choose moisture-wicking base layers. Pack merino wool or synthetic base layers in different weights. Avoid cotton completely — it stays wet and loses all insulating properties in Patagonia's damp conditions.
Plan for your extremities. Bring waterproof gloves, warm hat, sun hat, and wool socks. Pack liner gloves for dexterity and backup pairs of socks. Your hands and feet get cold first in Patagonian wind.
Pack weather-appropriate accessories. Include sunglasses, sunscreen SPF 30+, and a buff or neck gaiter. The sun reflects strongly off glaciers and snow, while wind protection for your neck makes a huge difference in comfort.
