W Trek Packing List: The Ultralight Gear Guide Most People Overcomplicate

Here's the dirty secret about packing for the W Trek: almost everyone brings too much stuff. I did too. After five days in Torres del Paine in January 2025 — soaked to the bone half the time, wind ripping across the passes hard enough to stagger me sideways — my biggest takeaway wasn't about the scenery. It was that my pack could've been five pounds lighter and I wouldn't have missed a thing.

The reason is simple, and it changes everything about how you pack for this trek: you can buy hot meals at almost every campsite. Pizza, pasta, empanadas, cold beer. This isn't backcountry. It's a well-serviced trail with refugios every few hours, and that means the standard "carry a week of freeze-dried dinners" approach is just dead weight on your back.

If you want the full picture of what this trek actually feels like day-by-day — the weather, the campsites, the parts that surprised me — I wrote a separate experience guide covering what the W Trek is really like. This article is the gear list. Weights, brands, what worked, what didn't, and what I'd cut next time.

The Food Myth That Adds 10 Pounds to Your Pack

I packed roughly 2 pounds of food per day. That was absurd. Most refugios along the W Trek serve real meals — we're talking plates of spaghetti, grilled sandwiches, soup. Some have full bars. Prices are steep (this is Patagonia, not Southeast Asia), but the food exists and it's hot and it's right there.

The only exception is Campamento Italiano/Francés, which has a small shop selling instant ramen, cookies, and basics — no cooked meals. Every other campsite either has a full restaurant or at least a decent shop.

What you actually need for food: breakfast supplies (instant coffee packets, oatmeal — or just buy breakfast at the refugio for around 8,000-12,000 CLP), trail snacks for between camps (energy bars, nuts, dried fruit, chocolate), and maybe one emergency freeze-dried dinner in case you roll into camp late and the kitchen is closed. That's it. Maybe a pound per day, max. Compared to a typical backcountry trip where you're hauling 8-10 pounds of food, this saves you a massive amount of weight and pack volume. It changes everything downstream — smaller pack, lighter sleep system since you're not as fatigued, less wear on your knees.

My Actual Kit: 12 Pounds Base Weight

Here's what I carried. Everything listed with weights because if you're going ultralight, grams matter and vague descriptions are useless. Full detailed breakdown with every item: lighterpack.com/r/ll2vt0.

Pack

What I used: Palante Desert Pack, 19.9 oz. Frameless, no hipbelt padding, 40-50L. This is a committed ultralight choice — you need to actually have a light enough kit to make a frameless pack comfortable, otherwise you'll be miserable. The pack rode well at 20-22 lbs total, which is about the ceiling for frameless.

If that sounds aggressive: Granite Gear Crown2 60 (2.3 lbs) hits a good middle ground — real frame, hipbelt, but not the 4-5 lb beast that most people default to. For full comfort, an Osprey Atmos AG 50 (4-5 lbs) is the standard recommendation, and honestly, if your total pack weight is pushing 30 lbs, the suspension is worth the extra weight. The approach here is similar to building a van — invest in the right foundation and everything else gets easier.

Shelter

What I used: Trekking pole tent (32 oz) with a Polycro groundsheet (2 oz). It rained. A lot. One night near Francés, the rain hit so hard it sounded like someone was throwing gravel at the fly. The wind was gusting strong enough that the trekking pole flexed and the whole shelter swayed. Nothing leaked — the Polycro groundsheet earned its two ounces that night — but I lay there at 2 AM listening to the fabric snap and wondered if the stakes would hold. They held. The tent looked like it had been through a car wash in the morning, but everything inside was dry. The Polycro saved me from some truly soupy ground conditions — Patagonia soil turns into this gray slurry when it's been raining for days, and anything touching the bare ground gets coated in it.

Alternatives: Zpacks Duplex (19 oz) if you want more wind protection with barely more weight, or the Big Agnes Copper Spur HV UL2 (3 lbs) if you want freestanding and easy setup — which matters when the wind is blowing sideways and you're trying to stake out a trekking pole shelter with numb fingers. Also worth knowing: several shops in Puerto Natales rent tents. If you're flying in and don't want to check gear or deal with finding fuel canisters, renting is genuinely reasonable.

Sleep System

What I used: Katabatic Alsek 20F quilt (26 oz), Big Agnes Air Core insulated pad (21 oz), Sea to Summit Aeros pillow (1.8 oz). Total sleep system: 3 lbs even.

The 20F rating was right. Patagonia summer nights drop into the mid-30s regularly, and with wind chill factored in, a 32F bag would have me waking up cold at 3 AM pulling on every layer I own. The quilt format saves weight over a mummy bag because there's no insulation underneath you (the pad handles that), and I'm a side sleeper so the open design works better for me anyway.

Budget alternatives: Marmot Phase 20F (2.5 lbs) or Kelty Cosmic 20F (3 lbs) are solid traditional bags. You're trading about a pound of weight for a much lower price tag. If you're only doing this one trek, spending $350+ on an ultralight quilt doesn't make sense — that money is better put toward, say, learning a new sport than shaving ounces.

Footwear

Trail runners. Not boots.

I wore Topo Pursuit 2s (24 oz per pair) and they were perfect. The W Trek trail is well-maintained — boardwalks over the boggy sections, clear paths through the forest, some rocky scrambling on the way up to the base of the towers. None of it requires ankle support. What it does require is something that dries fast, because your feet are going to get wet. Period. Trail runners dry overnight. Boots don't. You'll be sloshing through mud and puddles and stream crossings, and the speed at which your shoes dry is worth more than any amount of waterproof membrane.

If you absolutely need the psychological comfort of boots, Salomon Quest 4 GTX are the most popular choice on the trail. But watch everyone in boots at camp, limping around with blisters while the trail runner crowd walks barefoot and happy. At camp the second night, a guy in brand-new Scarpa boots was sitting on a rock with both shoes off, his heels raw and taped with what looked like half a roll of Leukotape. He'd bought the boots in Puerto Natales the day before the trek. I offered him ibuprofen and he looked at me like I'd offered him a kidney.

Trekking poles: Non-negotiable. The descents will wreck your knees without them, especially coming down from the French Valley where the trail drops steeply over loose rock. One critical note — you cannot carry trekking poles in airplane carry-on luggage. Either check your bag, buy cheap ones in Puerto Natales, or rent. Most outdoor shops in town offer rentals for a few thousand pesos per day.

Clothing System

Patagonia's weather is best described as "all of it, constantly." I had horizontal rain, blazing sun, near-freezing wind, and dead calm within the same afternoon. The layering system matters more than any individual piece.

Worn on body: convertible hat, sunglasses, breathable synthetic shirt, hiking shorts, merino buff (doubles as neck gaiter, headband, sleep mask — the single most versatile item I packed), Injinji toe socks. The toe socks sound gimmicky but they eliminated the between-toe blisters I always get on multi-day hikes.

Packed layers:

• Frogg Toggs rain jacket (5.5 oz) — costs about $20, weighs nothing, and it worked. It's not durable and it's not breathable and it looks like a trash bag. But it kept the rain out, which is the only thing a rain jacket actually needs to do. The expensive Gore-Tex shells half the other hikers wore weren't noticeably more waterproof; they were just more expensive.
• RAB Electron Pro down jacket (18 oz) — this was essential. Every evening at camp, the temperature drops fast once the sun dips behind the mountains. Having a warm puffy to throw on at camp is the difference between sitting outside watching the light change on the peaks and retreating into your tent at 6 PM.
• Lightweight midlayer (4 oz)
• Thermal bottoms (3 oz)
• Wind pants (3.6 oz) — I used these instead of rain pants and it was fine. Wind pants block the wind, dry in minutes, and weigh nothing. My legs got wet and I didn't care.
• Sleep socks (2 oz)

Total packed clothing: 2.26 lbs. The key insight: bring more warm layers than rain layers. You're going to get wet regardless. What matters is staying warm when wet, and being able to warm up at camp.

Cook System (Or Why I'd Skip It Next Time)

I brought a full cook system: BRS titanium stove (2 oz), Toaks 750ml pot (3.5 oz), mini fuel canister (4 oz), lighter, spoon. Total: 11 oz. And I used it almost exclusively for morning coffee.

With hot food available at every campsite, the stove was redundant. I'd boil water at 6 AM for coffee and instant oatmeal, and that was it. Eleven ounces — nearly three-quarters of a pound — for something I could've replaced by buying coffee at the refugio for a couple thousand pesos.

Next time, I'd either skip the stove entirely and buy all meals, or bring a tiny alcohol stove just for coffee. If you do want a cook system, a Jetboil MiniMo (14.5 oz) boils water faster but adds weight — only worth it if you're actually cooking meals, which you probably shouldn't be on this trek.

Water

Two Smartwater bottles (1.3 oz each, 1L each), Sawyer Squeeze filter (2 oz), CNOC Vecto 2L dirty water bag (3 oz). Total: 7.7 oz.

Water sources are everywhere on the W Trek. Streams, rivers, glacial runoff. I rarely carried more than 1.5L between camps. Many hikers skip the filter entirely and drink straight from the streams — the water comes from glacial sources and is probably fine. I used the filter because I'd rather carry 2 extra ounces than deal with giardia in the backcountry, but that's a personal risk calculation.

What I'd Change

After five days, here's the honest edit:

• Less food. A pound per day max, mostly snacks. Buy dinners at the refugios.
• Ditch the stove. Or bring the smallest possible alcohol stove for morning coffee only.
• Drop either the midlayer or the wind pants. Having both felt like one layer too many. The wind pants did more work, so the midlayer would be the cut.
• Smaller battery pack. I brought 20,000mAh and used maybe a third of it. 10,000mAh is plenty for five days if you're not doom-scrolling at camp.

Weight Comparison: Three Approaches

To give you a realistic range:

• Ultra-minimalist: ~12 lbs base, ~18 lbs loaded. Frameless pack, quilt, minimal clothing, no stove. Fast and light but requires experience and good gear.
• My setup (ultralight): ~16 lbs base, ~22 lbs loaded. Comfortable enough for anyone in decent shape, with some room for comfort items.
• Traditional backpacking: ~23-25 lbs base, ~29-31 lbs loaded. Full-featured tent, sleeping bag, stove, more clothing layers. Heavier but nothing wrong with it — the W Trek's campsites are close enough that the extra weight won't ruin the experience.

The point isn't that you need to go ultralight. It's that the food situation on the W Trek means everyone can pack lighter than they think, regardless of their gear philosophy.

The Stuff That Actually Matters

Forget the gear list for a second. Five things will make or break your W Trek experience more than any piece of equipment:

• Rain protection for your pack contents. Not your body — your stuff. A pack liner (a trash compactor bag works) keeps your sleeping bag and down jacket dry. Everything else can get wet. This is Patagonia. It will rain.
• Broken-in shoes. I don't care if they're trail runners or boots. Walk 50+ miles in them before the trek. If you show up in fresh-out-of-the-box shoes, you're going to have a very long five days.
• A real warm layer. Not a fleece you kind of like. A puffy jacket that makes you genuinely warm when you're wet and the wind is howling. This is the single most important piece of clothing you'll bring.
• Trekking poles. The descent from the French Valley alone justifies their existence.
• Accepting you'll get wet. The hikers who had the worst time were the ones fighting the rain — fussing with waterproof layers, trying to keep everything dry, getting frustrated. The hikers who had the best time were the ones who got wet on day one and stopped caring.

If you're still in the planning stage, the preparation guide covers permits, transportation, booking campsites, and the logistics of actually getting to Torres del Paine. And if you've done hut-to-hut hiking before — say, the DNT hut system in Norway — the W Trek has a similar structure but with significantly worse weather and significantly better food.
