For Everest Base Camp you need a cold-weather, high-altitude packing list: a layered clothing system, a down jacket, a sleeping bag rated to minus 15 C, broken-in boots and a 50 to 65 litre pack. Teahouses provide beds and meals, but the 5,364 m altitude and sub-zero nights mean insulation and sun protection are the priorities over ultralight weight savings.
How heavy should your Everest Base Camp pack be?
On the Everest Base Camp trek, many trekkers hire a porter who carries up to 15 kg, leaving you a light daypack. If you carry your own load, expect a base weight of 9 to 12 kg because of bulky cold-weather gear. A 50 to 65 litre pack works best; the Osprey Atmos AG 65 offers excellent load support for self-carriers, while those splitting gear with a porter manage with a 40 to 45 litre pack such as the Fjällräven Abisko Hike 35 as a daypack.
What clothing layers do you need?
Altitude makes temperatures swing wildly, from 15 C in the midday sun at Namche to minus 15 C at dawn at Gorak Shep, so a full layering system is essential:
- Two to three moisture-wicking base layer tops and bottoms
- An insulating midlayer fleece and a heavier down or synthetic jacket
- A waterproof, breathable hardshell jacket and trousers
- Trekking trousers plus insulated layers for camp
- Warm hat, sun hat, glove liners, insulated gloves and a buff
- Four to five pairs of merino trekking socks
The down jacket is the single most important garment for the high camps and early-morning Kala Patthar ascent.
What sleep system works at altitude?
Teahouse rooms are unheated and can drop well below freezing, so bring a sleeping bag rated to at least minus 15 C, ideally minus 20 C for the higher villages or winter trekking. Add a silk or fleece liner for extra warmth and hygiene, since blankets are limited. A lightweight inflatable pad adds insulation from cold floors. This sleep system is the difference between resting and shivering through the critical acclimatisation nights. A roomy carry like the Zpacks Arc Haul Ultra 60L swallows the bulky bag.
What footwear and foot care do you need?
Wear sturdy, broken-in waterproof trekking boots with good ankle support; the trail is rocky and crosses moraine near Base Camp. Pack camp shoes or sandals for the evenings, plenty of merino socks, and a thorough blister kit. At altitude, cold feet are a real risk, so consider a thicker sock for the highest days and keep boots inside your sleeping bag overnight at Gorak Shep to stop them freezing.
What altitude and health items are essential?
Altitude is the trek's defining hazard, so health gear matters as much as clothing. Carry a personal first-aid kit, water purification (tablets or a filter, as bottled water is costly and wasteful), high-SPF sun cream and lip balm, and category 4 glacier sunglasses, since UV is brutal above 4,000 m. Discuss acetazolamide for altitude sickness with your doctor before travel, and know the symptoms of AMS. Bring a 20,000 mAh power bank, as charging is paid and unreliable above Namche. Review acclimatisation advice from the Himalayan Rescue Association.
What documents and extras should you pack?
Bring your passport, the Sagarmatha National Park and local Khumbu permits, travel insurance that explicitly covers trekking and helicopter evacuation above 5,000 m, and enough Nepali rupees in cash, as there are no ATMs above Namche. Useful extras include a headtorch, trekking poles to spare your knees on the long descents, quick-dry towel and toiletries. Confirm permit requirements with the Nepal Tourism Board for 2026. For trekkers carrying a full self-supported load, a larger Gregory Baltoro 75 handles the combined cold-weather and safety kit.
| Category | Key item |
|---|---|
| Sleep | Bag rated to -15 C |
| Insulation | Down jacket |
| Eyes | Cat 4 sunglasses |
| Health | AMS meds + first aid |
Trekkers extending onto the Three Passes Trek need the same kit plus extra warmth and food capacity for the higher, longer crossings. Build your full checklist on HikeLoad before flying to Lukla in 2026.
What can you buy on the trail versus pack from home?
Namche Bazaar (3,440 m) is the Khumbu's last major resupply point, with gear shops selling everything from down jackets to trekking poles, much of it genuine brand-name stock and some of it convincing copies. You can rent a heavy sleeping bag and down jacket here cheaply if you would rather not fly with bulky kit, though quality varies, so inspect rentals carefully. Above Namche, prices climb steeply with altitude, and choice narrows to basics, so buy what you need lower down. Snacks, batteries, water purification and toilet paper are all available but cost two to three times Kathmandu prices at the high villages. The smart approach is to bring your critical items, boots, base layers, sun protection and any medication, from home, and treat Namche as a backup for anything forgotten.
Charging, hot showers and Wi-Fi are all available in teahouses for a fee that rises with altitude, so a 20,000 mAh power bank saves money and frustration. Pack your electronics and documents in a dry bag, since condensation and spills are common in the lodges. A foldable summit pack like the Zpacks Bagger Ultra 25L is handy for the Kala Patthar push when you leave your main bag at Gorak Shep.
How do you pack to manage the altitude?
Smart packing directly supports acclimatisation on the trek. Keep your daypack light, because every extra kilo is harder work in thin air; if you hire a porter, carry only water, snacks, sun protection and the layers you need during the day in a 35 to 45 litre pack such as the Fjällräven Abisko Hike 35. Carry at least 2 litres of water capacity and electrolyte tablets, since hydration is critical for adjusting to altitude and the dry air dehydrates you fast. Keep a small medical kit with painkillers, rehydration salts and any prescribed acetazolamide accessible rather than buried. Pack high-calorie snacks within reach so you keep eating even when altitude blunts your appetite, a common problem above 4,000 m. Self-carriers needing to fit a four-season bag and full down kit should choose a 60 to 65 litre pack like the Zpacks Arc Haul Ultra 60L, while those carrying everything plus extra cold-weather margin prefer a Gregory Baltoro 75. Logging your pack weight in HikeLoad before departure helps you trim grams that the altitude will magnify in 2026.
Frequently Asked Questions
How warm a sleeping bag do you need for Everest Base Camp?
A sleeping bag rated to at least minus 15 C is essential, and minus 20 C is safer for the highest villages or winter trekking. Teahouse rooms are unheated and routinely fall below freezing, so add a liner for extra warmth and hygiene.
What size backpack do you need for Everest Base Camp?
If a porter carries your main gear, a 40 to 45 litre daypack is enough. Self-carriers need a 50 to 65 litre pack to fit the bulky down jacket, four-season sleeping bag and cold-weather layers, with base weight typically 9 to 12 kg.
Do you need special sunglasses for Everest Base Camp?
Yes. UV intensity rises sharply with altitude, and reflective snow and ice near Base Camp make category 4 glacier sunglasses important to prevent snow blindness. Pair them with high-SPF sun cream and lip balm, as sunburn is common even in cold conditions.
Should you carry your own pack or hire a porter?
Many trekkers hire a porter, who typically carries up to 15 kg, leaving you a light daypack and helping you cope with the altitude. Self-carrying is possible for fit, experienced trekkers but adds 9 to 12 kg of load at elevations where every kilo feels heavier.
