There is a mountain climbers respect more than Everest, and it is not as tall. K2 stands 8,611 metres on the border of Pakistan and China, the second-highest mountain on Earth and, by some distance, the most dangerous of the giant peaks to climb. This guide explains why K2 is harder than Everest, the 1954 first ascent, the route on the back of our K2 design, the trek to base camp through Concordia, and what to wear.
How high is K2, and where is it?
K2 rises 8,611 metres in the Karakoram range, on the border between Pakistan and China. It sits in the Gilgit-Baltistan region, reached through the town of Skardu.
- Height: 8,611 m (second-highest on Earth)
- Range: Karakoram, Pakistan and China border
- Nickname: the Savage Mountain
- Name origin: Karakoram peak 2, a surveyor’s label from 1856 (Britannica)
Why is K2 harder to climb than Everest?
K2 is harder than Everest because it is steeper and more technical from bottom to top, with no easy side and weather that can turn in an hour. Everest’s normal route has fixed ropes, stocked camps and a queue on summit day. K2 has far less of that. The numbers tell the story:
| Everest | K2 | |
|---|---|---|
| Height | 8,849 m | 8,611 m |
| Difficulty | Long, high, but a trade route up high | Steep and technical throughout |
| First ascent | 1953 | 1954 |
| First winter ascent | 1980 | 2021 |
| Reputation | The highest | The Savage Mountain |
What is the route on the design?
The line on the back of the K2 hoodie and tee traces the climbing route up the hardest peak in the Karakoram, drawn as a single red thread. We did not draw K2 because it is pretty. We drew it because of what it asks, and we wanted the line to be the route rather than a postcard.
The classic line, the Abruzzi Spur, climbs in stages that every K2 climber knows by name:
- Advanced Base Camp at the foot of the spur
- House’s Chimney, a steep rock cleft around 6,600 m
- The Black Pyramid, a long band of mixed rock and ice
- The Shoulder, the last stretch of easier ground
- The Bottleneck, a gully beneath hanging ice, the most feared section, then the summit
Who first climbed K2?
K2 was first summited on 31 July 1954 by Achille Compagnoni and Lino Lacedelli, part of an Italian expedition led by Ardito Desio. The approach alone took weeks of walking in along the Baltoro Glacier. The mountain was not climbed in winter until January 2021, decades after Everest, by a team of Nepali climbers.
How do you get near K2?
You will not casually see K2. It hides deep in the Karakoram, days from the nearest road. The way most non-climbers reach it is the K2 Base Camp trek, a remote two to three week expedition.

The journey runs roughly like this:
- Fly to Skardu, the staging town in Gilgit-Baltistan
- Drive to Askole, the last village on the road
- Trek up the Baltoro Glacier over several days
- Reach Concordia, where four of the world’s fourteen 8,000-metre peaks rise around you
- Walk to K2 Base Camp (around 5,150 m) beneath the mountain itself
When is the best time to go?
K2 has a short, sharp season tied to the summer:
| Season | Months | Notes |
|---|---|---|
| Summer | June to August | The only realistic window for both the trek and climbing; warmest, longest days |
| Shoulder | May and September | Colder, riskier, far quieter |
| Winter | December to February | Brutal; reserved for elite expeditions |
What to wear, and where the design fits
On the Baltoro the days are hot and the nights are freezing, so the system is the same layering you would take to Everest Base Camp:
- Base layer: merino for warmth and sweat
- Mid layer: a brushed-cotton or fleece top for the cold camps
- Insulation: a down jacket for Concordia’s nights
- Shell: waterproof and windproof
Our K2 pieces are everyday cotton, not expedition kit. The heavyweight Cotton Heritage hoodie is the warm layer for the journey home and the days after; the garment-dyed tee is the one you wear all the time. Both carry the route across the back.
For the most-climbed line in the world instead, read about Everest and the South Col route, or the most recognisable peak of all, the Matterhorn.

Frequently Asked Questions
Is K2 really harder to climb than Everest?
Yes. K2 is 237 metres lower than Everest but steeper, more technical and far more exposed, with a much higher fatality rate. It has no straightforward route and the weather turns faster.
Where is K2?
On the Pakistan and China border in the Karakoram range, within the Gilgit-Baltistan region of Pakistan. The usual staging town is Skardu.
Can ordinary trekkers get near K2?
Yes, on the K2 Base Camp trek through Concordia and the Baltoro Glacier. It is a serious, remote expedition trek of two to three weeks, not a technical climb, but it needs real fitness and support.
When was K2 first climbed?
On 31 July 1954 by an Italian expedition led by Ardito Desio; Achille Compagnoni and Lino Lacedelli reached the summit. K2 was not climbed in winter until January 2021, decades after Everest.
Why is it called K2?
It is the surveyor’s designation, Karakoram peak 2, recorded in 1856. No local name was in wide use at the time, so the label stuck.
