The packing mistakes that actually end EBC treks aren’t about forgetting an item — they’re about gear choices that fail once you’re days from the nearest road: unbroken-in boots, cotton clothing, and a sleeping bag rated for the wrong temperature. None of these show up as a problem in Kathmandu. They show up on Day 4 at Dingboche, when there’s no gear shop left to fix them. This guide covers the mistakes we see repeatedly, and what to do instead.

Wearing Brand-New, Unbroken Boots
This is the single most avoidable trek-ending mistake we see. Stiff, unbroken boots create blisters within the first two days, and a bad blister on Day 2 at Namche Bazaar doesn’t heal — it gets worse every day you keep walking on it, because there’s no rest day built in early enough to let it recover. We’ve seen trekkers forced to slow down or shorten their trip because of a boot problem that a few weeks of proper break-in at home would have prevented entirely. Buy your boots at least a month before departure and hike in them repeatedly before you fly.
Packing Cotton Clothing
Cotton t-shirts and jeans feel comfortable in Kathmandu’s warmth, which is exactly why trekkers pack them without thinking twice. The problem shows up once you sweat on a climb into Namche or Dingboche: cotton holds that moisture against your skin instead of wicking it away, and once you stop moving, wet cotton pulls heat from your body far faster than dry synthetic or wool fabric does. At altitude, that’s not just uncomfortable — it’s a real contributor to hypothermia risk on cold, wind-exposed sections of the trail. Synthetic or merino wool base layers cost more but solve this completely.
Underrating Your Sleeping Bag
A three-season sleeping bag rated to 0°C feels like plenty when you’re shopping for it at home. It isn’t, once you’re at Gorak Shep or Lobuche, where teahouse rooms aren’t heated and night temperatures regularly drop well below freezing. Trekkers who underrate their bag end up sleeping in every layer they own just to get through the night, which means those layers aren’t dry and ready for the next day’s trek. A bag rated to -15°C to -20°C is the standard recommendation for EBC specifically because the margin matters more than the extra bulk.
Ignoring the Porter Weight Limit
Our porter policy allows 15kg per porter, and packing right up against that limit — or over it — creates a problem on Day 1, not later. An overweight duffel means renegotiating logistics at Lukla, adding an extra porter at extra cost, or leaving items behind at short notice. Weigh your packed duffel at home before you fly, not for the first time at the airport in Kathmandu.
Packing One Heavy Jacket Instead of Layers
A single heavyweight jacket seems simpler than a full layering system, but it fails on the actual trail conditions. You’ll overheat climbing into Namche in the same jacket that’s barely warm enough for a Gorak Shep evening, and once you’re sweating inside it, you’re now wet and cold at the same time. A base layer, mid layer, insulation layer, and shell — see our full packing list guide for the complete breakdown — lets you add or remove warmth as conditions change through the day, which a single jacket can’t do.
Buying Counterfeit Gear in Kathmandu
Thamel sells genuine gear alongside convincing counterfeits of major outdoor brands, often at similar-looking prices, and it’s genuinely difficult to tell them apart without knowing what to check. A counterfeit down jacket with thin or synthetic fill instead of real down performs noticeably worse in genuine cold, which is exactly the situation you can’t afford a gear failure in. Buy from established shops with a track record, check stitching and fill quality in person, and treat a suspiciously low price on a “premium brand” item as a warning sign, not a bargain.
Underestimating Sun and Glare at Altitude
Cold air at altitude doesn’t mean weak sun — UV exposure is significantly stronger the higher you climb, and snow and ice reflect a large share of it straight back at your face. Trekkers who pack sunscreen but skip proper UV-blocking sunglasses risk snow blindness, a genuinely painful and preventable condition, especially on bright days above Dingboche and around Kala Patthar. Regular sunglasses without real UV protection aren’t a substitute.
Packing for the Wrong Season
A packing list built for an October trek doesn’t automatically work for a January one, and the gap is bigger than most trekkers expect. January nights at Namche Bazaar average -8.5°C compared to October’s 1.2°C low — a difference that changes what sleeping bag rating and how many insulation layers you actually need. Check our seasonal weather guide before finalizing your gear list, and adjust for your actual travel month rather than a generic list.
Frequently Asked Questions
Yes, and boots are the most common cause. A serious blister from unbroken boots, caught early enough, can be managed — but ignored or aggravated over several more trekking days, it can force a trekker to stop well short of Base Camp. It’s one of the few packing mistakes with no easy fix once you’re on the trail.
For core safety items — your down jacket and sleeping bag — yes, from a shop you trust. Locally made gear from established Thamel shops is often good value and not the same thing as counterfeit gear; the risk is specifically with suspiciously cheap “premium brand” items that may not perform as advertised.
Not weighing the duffel bag before departure. Trekkers plan their clothing carefully but guess at total weight, then discover at Lukla that they’re over the 15kg porter limit with no easy way to redistribute gear on the spot. A home scale check the week before you fly avoids this entirely.
