This is the list of items I took with me for the for the Everest Base Camp Trek, be mindful that I am typically a light traveler, others I was with struggled to reduce their bags to an acceptable weight. Have a look at my guide "EBC Shopping List" for more details about the type of clothing and brands I used and can highly recommend:

Essential Clothing:

• Base layers x 3
• Insulating layers x 3
• Fleece x 1
• Insulated Jacket x 1 
• Waterproof and windproof jacket x 1
• Trekking trousers and shorts x 2
• Thermal underwear x 5
• Hat, lining gloves, thick insulated gloves, scarf and bandana x 1

Footwear:

• Sturdy hiking boots (broken in)
• Good quality hiking boots suitable for the
• Walk are critical, you’ll see locals running up and down in trainers and sandals, please don’t try this! If you start experiencing problems with your feet this will not be an enjoyable trek.
• Trekking socks x 5 (wool or synthetic)
• Normal socks to sleep in and for evenings x 2
• Sandals or comfortable shoes for evenings.

As soon as you reach your accommodation for the evening take your boots off, take your socks off and air your feet, sweaty feet in sweaty boots results in frozen boots the following morning (I experienced this one day, it’s not too enjoyable). If needed dry your boots near the heater in the communal area.

Gear and Equipment:

• Backpack - Various sources online suggest 60-70L if carrying your own stuff, I used a 50L and it was more than enough, I had a laptop for remote work too.
• Sleeping bag (appropriate for cold temperatures)
• Headlamp with extra batteries
• Sunglasses and sunhat
• Water bottles or hydration system
• Basic first aid kit
• Waterproof bag cover

Personal Items

• Toiletries (toothbrush, toothpaste, biodegradable soap, etc.)
• Sunscreen and lip balm with SPF
• Personal medications and any necessary prescriptions
• Diamox (acetazolamide) – Alititude sickness tablets. I would recommend having these spare just in case you need them and I would also suggest you purchase them from a pharmacy at home, there had been reports of fake Diamox tablets in Kathmandu
• Hand sanitizer and wet wipes
• Toilet roll

Electronics

• Camera or smartphone for photos
• Portable charger or power bank/solar bank
• Spare batteries or chargers

Documents

• Passport and necessary visas
• Trek passes (Details below)
• Travel insurance documents
• Cash in local currency ($600 minimum)

Snacks and Extras:

Energy bars, chocolates, or trail mix

Water purification tablets or a water filter (I used water purification tablets in boiled water, overkill I know but I thought it was better to be as safe as possible)

Remember, it's essential to pack light and only carry what you need, as every extra kilogram can be burdensome at high altitudes. Also, consider the time of year you'll be trekking, as weather conditions can greatly influence your packing needs. If you are traveling with an agency like Heaven Himalaya, then they will give you a porter to carry your bags, if not its you who carries, so be mindful of the packing.
