Packing Philosophy: Light is Right

Every experienced Nepal trekker eventually arrives at the same conclusion: they packed too much the first time. The mountains have a way of clarifying exactly how much a full pack weighs after hour five of a 1,200 m ascent. The standard advice - bring everything you might need - is the wrong starting point. The better question is: what will I genuinely use every day?

For a Nepal trek, your day pack (what you carry while your porter carries the main bag) should be 10 - 14 kg absolute maximum. Your porter bag (what they carry) should be no more than 15 kg. Experienced trekkers routinely complete EBC with a 7 kg carry. Start with this list and then aggressively cut anything you "might" need but can't say you'll definitely use.

Footwear

Your boots are the single most important item. Get this wrong and nothing else matters.

Trekking Boots

For any trek above 4,000 m - Everest Base Camp, Annapurna Circuit, Manaslu, Dolpo - you need waterproof leather or synthetic mid-to-high cut trekking boots with a Vibram or equivalent rubber sole and ankle support. Gore-Tex or equivalent waterproof membrane is essential: the high passes above 5,000 m regularly see snow, and wet feet at altitude are a serious cold-injury risk. Break your boots in thoroughly (100+ km minimum) before arriving in Nepal. New boots cause blisters; blisters end treks.

For lower-altitude treks (Poon Hill, Langtang lower sections, Annapurna Panorama) trail runners or approach shoes are viable in dry conditions, though the unpredictability of mountain weather makes waterproof boots a safer choice for multi-day itineraries.

Camp Shoes

Lightweight sandals or Crocs for the teahouse. After 8 hours in boots, your feet need air. These can be used as bathroom shoes (essential at most teahouses) and for short walks around camp. Weight: 300 - 500 g.

Gaiters

Short trail gaiters are useful on muddy lower-altitude trails (monsoon or spring) and above 4,500 m in late autumn when light snow dusts the high passes. Not essential for dry autumn trekking to EBC, but worth considering if you're doing the high passes (Renjo La, Cho La, Kongma La) or the Annapurna Circuit's Thorong La in late October.

Liner Socks and Wool Socks

Bring 3 - 4 pairs of wool (merino) trekking socks and 2 - 3 pairs of thin liner socks. Merino wool manages moisture and temperature simultaneously. Avoid 100% cotton socks completely - cotton holds moisture and causes blisters. Change into dry socks at the teahouse every evening. Your feet will thank you.

Clothing Layers

The Nepal layering system has three components: base layer (next to skin), mid-layer (insulation), and outer layer (wind and waterproof). Everything should be synthetic or wool - no cotton above the first camp.

Base Layer

Merino wool long-sleeve top × 2
Merino wool long-sleeve bottom × 1
Merino wool briefs × 3
Lightweight synthetic trekking trousers × 2 (zip-off legs optional)
Trekking shirt (short sleeve, synthetic) × 2

Mid Layer

Fleece jacket (100 - 200 weight) - essential for evenings in teahouses above 3,000 m
Down or synthetic puffer jacket - critical above 4,000 m; temperatures drop to -10°C+ at Gorak Shep in October nights
Fleece or softshell trousers - for cold evenings; the trekking trousers alone are insufficient above 4,500 m at night

Outer Layer

Waterproof/windproof shell jacket (Gore-Tex or equivalent) - the most important outer layer; doubles as windbreaker and rain jacket
Waterproof shell trousers - optional for short treks; essential for extended high-altitude routes and the Annapurna Circuit

Accessories

Wool or synthetic beanie (covers ears)
Balaclava or buff × 1 - for very cold early-morning starts at Kala Patthar
Sun hat with brim - UV at altitude is intense; protect your face and neck
Lightweight liner gloves + insulated outer gloves - the combination handles the range from 5°C to -15°C
Neck gaiter (buff)
Gaiters (if needed per above)

Sleeping System

Teahouses above Namche Bazaar provide blankets, but the blankets are heavily used and not always warm enough at altitude. A sleeping bag rated to -15°C (comfort rating, not limit) is standard for EBC. Sleeping bag liners add 5°C and are useful for hygiene. If you're doing a camping trek (Dolpo, Dhaulagiri Circuit, any remote route), you need a -20°C bag for high camps above 5,000 m.

A sleeping bag can be rented in Kathmandu or Namche Bazaar - see the renting section below.

Daypack and Bag

Main bag/duffel: A 60 - 70 litre duffel bag (not a backpack) that your porter carries. Duffels compress better than packs and are easier for porters to handle. Waterproof dry bag liner inside.
Day pack: 25 - 30 litres for what you carry yourself: water, snacks, camera, extra layer, first aid, headlamp, sleeping bag if not in duffel. Rain cover included or buy one separately.

Electronics and Navigation

Headlamp with spare batteries - essential for early morning starts (Kala Patthar at 04:30) and teahouse hallways without electricity
Powerbank (20,000 mAh minimum) - charging at teahouses costs NPR 200 - 500 per device and may not be available; a powerbank covers phones, GPS, and cameras for 3 - 5 days
Phone with offline maps (Maps.me or Gaia GPS with Khumbu/Annapurna map downloaded offline)
Camera - a mirrorless or DSLR with a 24 - 200 mm zoom covers nearly every Nepal trekking shot; the 70 - 200 mm range is where mountain portraits happen
Extra camera batteries (cold kills battery life; carry 2 - 3 spares for above 4,000 m)
Universal travel adapter - Nepal uses Type C and D outlets primarily

Medical and First Aid

Your guide carries a main first aid kit, but you should have your own personal kit. The essentials:

Diamox (Acetazolamide) 250 mg - altitude sickness prophylactic; discuss with your doctor before departure; start 1 tablet twice daily from 2 days before reaching 3,000 m
Ibuprofen and/or paracetamol - for high-altitude headaches
Blister kit (Compeed, moleskin, needle, antiseptic)
Diarrhea treatment (Imodium + oral rehydration salts) - one of the most common trek disruptions
Antiseptic wipes and small wound dressings
Pulse oximeter - essential above 4,000 m; available in Kathmandu and Namche for USD 15 - 20 if not bringing your own
Water purification tablets or SteriPen UV - teahouse water is safe above Namche but belt-and-suspenders caution is wise
Sunscreen SPF 50+ - UV at 5,000 m is approximately 3× stronger than sea level
Lip balm with SPF
Eye drops - the altitude and wind cause eye irritation above 4,000 m
Insect repellent - for lower altitude sections and Kathmandu

Documents and Money

Passport (original - required for all permit checks; do not leave it in Kathmandu)
Nepal visa stamp/entry proof
Travel insurance policy document and emergency contact number (keep a physical copy)
Trekking permit copies (your guide carries originals but you should have a photo on your phone)
USD cash - Nepali Rupees are required for all teahouses; exchange rate for USD is best in Kathmandu; ATMs exist in Namche Bazaar but are not reliable above that
Budget NPR 2,500 - 4,500 per day for teahouse accommodation and meals above Namche

What to Rent or Buy in Kathmandu

Kathmandu's Thamel district has excellent rental and purchase options for trekking gear. Renting is cost-effective for items you won't reuse after Nepal:

Sleeping bag (NPR 100 - 200/day) - sensible to rent if you don't own one
Down jacket (NPR 150 - 300/day) - rent unless you'll use it regularly at home
Trekking poles (NPR 100 - 150/day) - worth renting for any trek with significant altitude gain
Duffel bag - often provided by trekking agencies; or purchase a local Sherpa brand bag (USD 15 - 25, excellent quality)

Buy in Kathmandu if needed: headlamps, buffs, merino wool base layers (Kathmandu brand or similar), trail socks, Nalgene bottles, pulse oximeter. North Face and Marmot knockoffs are widely available - reasonable quality for budget trekkers, though waterproofing may not match genuine brands.

What to Leave at Home

Jeans and cotton trousers - cotton kills at altitude
Heavy hardback books - download e-books; the Kindle weight is worth it
Hairdryer or electric shaver - electricity is limited and precious above Namche
Excessive toiletries - deodorant, multiple shampoos, conditioner; you won't shower above Namche; a small wet-wipe pack covers the basics
Multiple camera bodies and lens systems - the weight-to-reward ratio does not favour trekking with more than one body and two lenses
Expensive jewelry - security and practicality argue against it

Pack your bag, weigh it, then take out 20%. Repeat until it's 10 - 12 kg. Then go to Nepal and climb something extraordinary.
