OCÚN Twist Tech Eco: The First Eco-Friendly Harness Gear News

Experience the ultimate in comfort and versatility with our sustainable climbing harness. Made from recycled materials, this versatile harness allows you to climb with confidence, knowing you're doing your part for the planet. 

In 2023, we proudly introduced Twist Tech Eco and its lady version, the first eco-friendly harness, which is made dominantly from recycled and bio-based materials. It is a comfortable 3-buckle harness intended for all-round use - suitable for sport climbing, mountaineering and via ferrata. 


Our goal was to create a harness made of as much recycled or bio-based material as possible. All of this had to be done in a highly functional way with no compromise on safety or durability of the final product. We have paid special attention to user comfort as well. Because Twist Tech Eco is a harness designed with sustainability in mind, we wanted it to be suitable for as many climbers as possible. That is why we focused on its functional all-round design.


Its unique design has won the prestigious ISPO AWARD 2023, marking a significant leap in sustainable climbing equipment. This eco-conscious innovation changes the game for climbers, reducing their ecological footprint and maintaining a high level of engineered gear. Twist Tech Eco meets both high performance and environmental needs, offering climbers a more sustainable future while pushing their limits.


For this new harness, the time-tested system of a movable waist webbing has been used, so that it adapts ideally to its user. The sandwich construction ensures maximum comfort. TWIST TECH ECO is also available in UNISEX and LADY versions, which better supports the anatomy of the female body. The name Tech indicates that the harness is equipped with 5 gear loops and and two carytool slot. Three stainless steel safety buckles are a standard feature.

Great news to hear that your harness is saving the planet whilst having flown (probably...) half way across Europe to play on some rocks!

I thought this was a step in the right direction, in fact most harness are made in the china or other parts of the far east. If you look at the most commonly sold British brand harness models they are also made in the EU.

I would have thought the number of people flying around the world the escape the British weather to climb was more of a problem?

I am surprised they didn't go the whole hog and claim the harness as organic. Long chain hydrocarbons being organic chemicals.

Green stickers, the new snake oil.

I was being tongue in cheek on the whole, though it'd be interesting to find out just where total carbon footprints add up in our climbing exploits. How much does your harness produce compared to your cam, to your trip to a local crag, to a trip to the mountains or indeed a foreign trip - even UKC has a footprint, how much do our logbooks create? I remember reading once that twitter used as much energy as the entire city of Frankfurt. I wonder if UKC is equivalent to maybe a Hathersage or Llanberis? I wonder if any climbing journo would be interesting in producing such a piece?

In the interests of transparency I do own some Adidas clothing produced using recycled materials, but only because they were bargain sample units from the outlet at Stockport. The quality is still really good, wouldn't be able to tell the difference :)
