Do I really need a waterproof tent?

Yes. The wind and rain in Patagonia can penetrate non-technical tents. Ensure your tent has a high hydrostatic head rating and strong poles.

Is it better to rent gear or bring my own?

Bring your own boots and rain gear. Rent large items like sleeping bags and tents in Puerto Natales or El Chaltén to save on airline baggage fees.

How cold does it get?

Even in mid-summer (January), temperatures can drop to near freezing (0°C/32°F) at night or during sudden storms, especially at high elevations.

Essential Gear for Trekking in Patagonia

Patagonia's weather is notoriously volatile; you need a strict layering system, high-quality waterproof shells, and broken-in boots. Pack for four seasons in a single day, regardless of the calendar month.

Choose your footwear. Bring mid-cut, waterproof hiking boots with aggressive lugs. Ensure you have worn them for at least 30 miles of hiking before your trip to prevent blisters. Pair them with merino wool socks—bring three pairs.
Master the layering system. Wear a synthetic or merino base layer, a fleece mid-layer, and a synthetic 'puffy' jacket. Carry a high-quality hardshell rain jacket with at least 20,000mm waterproofing; Patagonia wind will shred cheap rain gear.
Select the right pack. For day hikes, a 20-30 liter pack with a built-in rain cover is sufficient. For multi-day circuits like the O-Trek, use a 50-65 liter pack with a load-bearing hip belt and a dedicated waterproof dry bag liner inside.
Pack trekking poles. Use adjustable trekking poles with rubber tips. They are non-negotiable for stability on loose scree slopes and for saving your knees during the steep, sustained descents.
