The best gear for the Everest Three Passes Trek is a 50–60 litre pack, a sleeping bag rated to -15 °C, microspikes for the Cho La glacier, and a robust four-layer clothing system. The 166 km loop crosses three passes above 5,300 m, so cold-weather warmth and traction outrank ultralight weight savings.
What gear does the Three Passes Trek demand that EBC does not?
The Everest Three Passes Trek is teahouse-based, but its high passes add three gear requirements over the standard route: microspikes for Cho La's glacier, a warmer sleeping bag for camps above 4,800 m, and more pack capacity for pass-day food and layers. Get these right and the rest mirrors a normal Everest kit.
Which backpack is best for the Three Passes Trek?
Self-carry trekkers should choose 50–60 litres. The Zpacks Arc Haul Ultra 60 stays under 800 g while carrying the extra insulation, microspikes and food the passes demand. For maximum load support when you are tired at altitude, the Deuter Aircontact Lite 45+10 transfers weight to the hips better than almost any pack in its class. Porter-supported hikers can use a smaller summit pack like the Zpacks Arc Scout 37L on pass days, carrying only water, layers and snacks.
How warm should your sleep and insulation system be?
High camps at Lobuche (4,940 m), Gokyo (4,790 m) and Dzongla (4,830 m) are colder than anything on the standard route. Carry a sleeping bag with a -15 °C comfort rating plus a liner for another 3–5 °C, and an insulated pad with R-value 3 or higher. For clothing, run a warmer four-layer system: two base layers, a fleece, a synthetic active-insulation jacket, an 800-fill down jacket of 400–500 g, and a 3-layer hardshell.
Traction and poles: the pass essentials
The single most important Three Passes-specific item is microspikes or lightweight crampons for the Cho La glacier, which is icy at dawn. Trekking poles are essential too, cutting knee load by up to 25 percent on the steep stone staircases off Renjo La and stabilising you on the boulder fields below Kongma La.
The Three Passes gear checklist
| Item | Spec |
|---|---|
| Backpack | 50–60 L, supportive hip belt |
| Sleeping bag | -15 °C comfort rating |
| Traction | Microspikes for Cho La |
| Insulation | 800-fill down, 400–500 g |
| Sunglasses | Category 4 glacier glasses |
| Power | 20,000 mAh power bank |
Footwear, sun and charging
Wear broken-in mid-cut waterproof boots that accept microspikes, and bring camp shoes for evenings. At over 5,300 m on snow, category-4 glacier sunglasses and SPF 50 sunscreen are non-negotiable, with UV exceeding index 10. A 20,000 mAh power bank covers your phone, headlamp and GPS, since teahouse charging is scarce and expensive above 4,000 m.
Gear you can rent or buy in Nepal in 2026
As of 2026, Kathmandu and Namche Bazaar rent four-season sleeping bags, down jackets and poles, and Namche shops sell microspikes, sunscreen and gloves. This lets you fly light while still arriving glacier-ready. If you are deciding between routes, the gentler Everest Base Camp Trek needs the same base kit minus the microspikes and warmest bag; a ventilated Osprey Atmos AG 50 is ample there. Confirm permit rules through the Nepal Tourism Board and altitude advice from the Himalayan Rescue Association.
How much should you budget for Three Passes gear?
A full Three Passes kit bought new costs roughly EUR 1,400–2,800, slightly more than a standard Everest setup because of the warmer sleeping bag and traction devices. You can cut costs in Nepal: as of 2026, Kathmandu and Namche rent four-season bags and down jackets for EUR 1–3 per day each, and Namche sells microspikes outright for EUR 25–40. Prioritise spending on the three items that most affect safety and comfort, the pack, the -15 °C bag and reliable traction, and rent or buy the rest locally. A quality load-hauling pack like the Deuter Aircontact Core 50+10 repays its cost in comfort over the long pass days.
What gear mistakes are most common on the high passes?
The biggest errors are arriving without microspikes for Cho La (5,420 m), bringing a summer-rated sleeping bag that fails at the -15 °C high camps, and forgetting category-4 glacier sunglasses, which invites snow blindness above 5,300 m. Others skimp on insulated gloves, underestimate pass-day food, or choose a pack too small to carry traction and extra layers. A roomy 50–60 litre carrier such as the Zpacks Arc Haul Ultra 60 or the ventilated Osprey Aether 65 prevents the over-stuffing that strains your back. The same kit, minus microspikes and the warmest bag, also covers the standard Everest Base Camp Trek, so buying for the harder Three Passes route future-proofs your setup for 2026 and beyond.
How do you layer for sub-zero pass mornings?
The passes are cold and windswept even in October, so your clothing system runs warmer than on the standard route. Build it in four parts: two merino base layers, a fleece plus a synthetic active-insulation jacket, an 800-fill down jacket of 400–500 g for pass mornings, and a 3-layer waterproof hardshell jacket and trousers. Add insulated gloves with liners, two warm hats and a buff for the dawn wind chill, which can feel like -20 °C on Kongma La (5,535 m). Category-4 glacier sunglasses are essential on the snow-covered passes, where UV exceeds index 10 and snow blindness is a real risk. Keep the down jacket and gloves at the top of your pack for fast access. A 50–60 litre carrier such as the load-hauling Deuter Aircontact Core 50+10 or the ultralight Zpacks Arc Haul Ultra 60 holds the extra insulation, and the same layering covers the standard route too on the Three Passes loop in 2026.
Frequently Asked Questions
What size backpack do you need for the Three Passes Trek?
A 50–60 litre pack suits self-carry trekkers, with room for a -15 °C bag, microspikes and pass-day food. Porter-supported hikers can use a 35–40 litre summit pack for daily water, snacks and layers on the long pass crossings.
Are microspikes essential for the Three Passes Trek?
Yes, for the Cho La (5,420 m) glacier, which is often icy at dawn. Microspikes provide enough grip in peak season; full crampons are usually unnecessary. They can be bought or rented in Namche Bazaar if you do not own a pair.
What sleeping bag temperature rating do you need?
Aim for a -15 °C comfort rating because high camps at Lobuche, Gokyo and Dzongla all sit above 4,800 m. A silk or fleece liner adds another 3–5 °C and keeps the bag clean over a three-week trek.
Can you rent gear for the Three Passes Trek in Nepal?
Yes. As of 2026 Kathmandu and Namche rent down jackets, four-season sleeping bags and trekking poles, and Namche sells microspikes and sunscreen. This is the cheapest way to avoid flying with bulky cold-weather equipment.
Do you need a different kit than for Everest Base Camp?
Mostly the same, with three additions: microspikes for Cho La, a warmer (-15 °C) sleeping bag, and slightly more pack volume for longer pass days. The clothing, footwear and health kit are otherwise identical to the standard Everest route.
Can one backpack cover both the standard and Three Passes routes?
Yes. A 50–60 litre pack with a strong hip belt, such as the Zpacks Arc Haul Ultra 60 or Deuter Aircontact Core 50+10, carries the warmer bag, microspikes and pass-day food the loop needs while still working well on the standard Everest Base Camp route. Buying for the harder route future-proofs your kit for 2026 and beyond.
