Should I buy my boots in Patagonia?

No. Never break in new boots on a Patagonia trek. Buy them at least 3 months early and hike in them locally to prevent blisters.

Can I get away with a cheap rain jacket?

If it is not truly waterproof, no. Patagonia weather changes in minutes. If your jacket wets out, you face a serious risk of hypothermia.

Budgeting for Patagonia Trekking Gear

Budget between $800 and $1,500 USD for technical gear if you are starting from scratch. Prioritize quality boots and a high-quality rain shell, while renting bulky items like sleeping bags and trekking poles once you arrive.

Audit your existing kit. Before buying anything, check if you already own moisture-wicking synthetic base layers or a thermal fleece. Do not bring cotton; it stays wet and will make you dangerously cold in Patagonian wind.
Prioritize the 'Big Three'. Invest your budget primarily in your boots, your rain shell, and your daypack. These are your protection against the elements and are not worth skimping on. Plan to spend $200 on boots, $250 on a GORE-TEX jacket, and $150 on a 30L-40L pack.
Rent locally to save weight and cash. If you are trekking the W or O circuit, rent sleeping bags and trekking poles in Puerto Natales. You will save approximately $200 in gear purchase costs and save significant luggage space. Daily rental for a quality sleeping bag is roughly $8.
Buy used or previous-season items. Check sites like Geartrade or local consignment shops for technical pants and down jackets. You do not need the current year's model to stay warm; you need high-loft insulation and DWR (Durable Water Repellent) coatings.
