If you’re heading to Everest Base Camp (EBC) and wondering what size backpack you need, you’re not alone. With so many options—20L, 30L, 40L+—it’s easy to get overwhelmed. But the right answer depends on whether you have a porter and what you’ll be carrying during the day. Let’s break it down so you can find your perfect trekking backpack.
What Size Backpack Do You Need?
✔ If You Have a Porter → 25L to 35L is ideal.
✔ If You’re Carrying All Your Gear → You’ll need a much bigger pack, 50L+ (but most trekkers use porters).
Most trekkers hire a porter, meaning they only need to carry daily essentials like water, snacks, an extra layer, gloves, and rain gear. The sweet spot for most hikers is between 30-35L—big enough for layers but not too bulky.
Why Not Just a 20L Pack?
Some trekkers get by with a 20L pack, but it can be tight. Here’s why:
🟢 20L is fine if you only carry the bare minimum—water, sunglasses, sunblock, phone, and maybe a light jacket.
🔴 But—mountain weather is unpredictable. You’ll likely need to stash layers, gloves, rain gear, snacks, and a battery pack throughout the day. A 20L bag might feel too cramped.
Best Recommendation? 30-35L gives you room without adding much weight.
What to Look for in an EBC Backpack
✔ Hydration System Compatible – Many trekkers recommend Osprey backpacks with a built-in hydration bladder (so you don’t have to fumble with bottles).
✔ Comfortable Straps & Ventilation – You’ll wear this pack for hours each day, so look for padded shoulder straps and a ventilated back panel.
✔ Multiple Compartments – Easy access to rain gear, gloves, and snacks is a lifesaver when the weather changes fast.
✔ Water-Resistant or Rain Cover – A light rain cover is a must—weather shifts quickly at high altitudes.
Final Verdict: What Should You Get?
If you’re using a porter, a 30-35L backpack is the safest choice—it gives you enough space for layers without being overstuffed. If you’re going super minimalist, a 20L pack can work, but it’s tight.
