How to Pack for Patagonia’s Four-Seasons-in-a-Day Weather

Pack using a strict three-layer system—base, insulation, and shell—regardless of the season. Focus on moisture-wicking synthetic or wool fabrics and skip cotton entirely to stay dry and warm during rapid weather shifts.

  1. Prioritize a hard-shell outer layer. The wind in Patagonia can gust up to 100km/h. Bring a high-quality, windproof, and waterproof jacket with a hood. It must be able to withstand horizontal rain.
  2. Master the mid-layer. Bring a packable down or synthetic puffer jacket for cold mornings, and a fleece or wool sweater for active hiking. You should be able to remove these easily as you warm up.
  3. Choose your base layers. Carry two sets of merino wool or synthetic long-sleeve base layers. Avoid cotton at all costs; if it gets wet from sweat or rain, it will not dry and will sap your body heat.
  4. Select the right footwear. Break in a pair of waterproof mid-cut hiking boots at least two weeks before your trip. The terrain is rocky and uneven; you need ankle support and a stiff sole.
  5. Don't forget the accessories. Pack a thin beanie, lightweight waterproof gloves, and a buff. You will reach for these even in the middle of summer when the wind chill hits.
Should I bring an umbrella?
No. The wind is too strong. It will break your umbrella in minutes. Use a rain jacket with a hood instead.
Is it really that windy?
Yes. Expect sustained winds that can make walking difficult. Use trekking poles to improve your balance on exposed ridges.
Do I need technical mountaineering gear?
If you are doing standard trekking like the W-Trek or Fitz Roy, no. If you are doing glacier trekking on ice, you will be provided with crampons and ice axes by your tour operator.
