Dyneema: The world’s lightest, strongest material

Exhausted, I dragged the OMM Phantom 20 backpack across the rough face the Silurian sedimentary rocks of Scotland’s Southern Uplands unconcerned for the state of my backpack. I’d been running, well struggling, for 11 hours on the 2015 Original Mountain Marathon. It was now dark and we were scrambling down a pitch-black rocky step. I was broken, scraped, slightly torn. My backpack, not that I’d given it much thought, was fine. It had to be, the OMM is one of the toughest challenges in the UK. No wonder then, they use Dyneema to make the packs. It is, after all, world’s strongest fabric that is said by manufacturers to be 15 times stronger than steel. It has been used to stop bullets, repair human joints, moor oil rigs and make really, really, light waterproof jackets.
A case in point is Black Yak’s Emergency Jacket that won the Gold Award at ISPO, the industry showcase in Munich. South Korean brand Black Yak produced the jacket that weighs only 54 grams, the lightest in the world. It doesn’t have any pockets and should be used exactly as the name suggests. Black Yak’s jacket is not going to replace your three-layer Gore-Tex any time soon, but it highlights the possibilities for Dyneema.
Dyneema, formerly Cuben fibre, has, of course, been used in ultralight outdoors products before, particularly in backpacks from the likes ofHyperlite Mountain Gear, the aforementionedOMMandMountain Laurel Designs(MLD). It is very lightweight, extremely tough-wearing, soft and hydrophobic. Ron Bell of MLD, Mike St Pierre of Hyperlite Mountain Gear and Gen Shimizu ofYamaappear in a film about Dyneema called Ultralight (see below) extolling the virtues of Dyneema.
On ultralight long-distance events such as the TGO Challenge, a two-week coast-to-coast backpack across Scotland, it is Mountain Laurel Designs equipment that many carry. The triumvirate of shelter, sleeping system and pack is often where most weight can be shed, all products – no coincidence – that readily use Dyneema. Gear is often weighed out to the gram –who needs the handle of toothbrush anyway? (Note: no one has used Dyneema for a tooth brush).

Dyneema are now hoping to push the use of the product in more clothing and equipment across the outdoor industry. The recently-launched ‘Dyneema Project’ is designed to bring the material to a wider apparel market through collaboration with more brands including as adidas and, curveball, Levi’s who used to reinforce 501 jeans.
Dyneema was discovered in 1963 by Dr Albert Pennings while ‘stirring in a pot’. He noticed that the wisps of polythylene crystals were very long and therefore very strong. It’s since been used to upturn the stranded cruise ship Costa Concordia in Italy and tether satellites in space.
“It’s funny to think it all just started with some stirring in a pot,” said Dr Albert Pennings. By 1968, he was able to pull these wisps out in the form of a thread-like material. “In a sense it was simple: we’d have this string of swollen stuff and we’d hold it over a hot plate and stretch it out with our hands. The solvent would evaporate out, and we were left with a tiny string – a really strong polyethylene fibre.”
However, it wasn’t until 1978, after years of experimentation, that the fibre could be produced on an industrial scale, gaining a patent in 1979. Today, it’s used across many industries with hundreds of applications, but it’s in apparel where the Dyneema Project is focussed… and they are now looking for more brand to collaborate with. Sidetracked will be testing some Dyneema products in the near future. But we can already vouch for OMM’s Phantom 25 –it certainly fared better than me at the end of the Original Mountain Marathon.

I'm an enthusiast with a deep understanding of outdoor gear materials, particularly Dyneema, the world's lightest and strongest fabric. My knowledge extends to its applications in various industries, ranging from adventure gear to apparel. In the article you provided, the author, Daniel Neilson, explores the use of Dyneema in outdoor equipment, specifically backpacks, and highlights its exceptional strength and lightweight properties.
Dyneema, formerly known as Cuben fiber, is a fabric that is claimed by manufacturers to be 15 times stronger than steel. It has been utilized in a variety of high-performance products, including backpacks for challenging events like the Original Mountain Marathon (OMM). The OMM backpack, made with Dyneema, withstands the rigors of demanding challenges, such as the 2015 race mentioned in the article.
The article mentions Black Yak's Emergency Jacket, made with Dyneema, which weighs only 54 grams, making it the lightest jacket in the world. While not intended to replace traditional three-layer Gore-Tex jackets, it demonstrates the possibilities for Dyneema in creating extremely lightweight yet durable outdoor apparel.
Notably, Dyneema has been featured in ultralight outdoor products from brands like Hyperlite Mountain Gear, OMM, and Mountain Laurel Designs (MLD). These products, including shelters, sleeping systems, and backpacks, showcase Dyneema's characteristics of being lightweight, tough-wearing, soft, and hydrophobic.
The article also introduces the Dyneema Project, a recent initiative aimed at expanding the use of Dyneema in clothing and equipment across the outdoor industry. The project involves collaborations with brands such as adidas and Levi's, indicating a move toward incorporating Dyneema into mainstream apparel.
The historical background of Dyneema is briefly touched upon, mentioning its discovery in 1963 by Dr. Albert Pennings while experimenting in a laboratory. It took years of experimentation before Dyneema could be produced on an industrial scale, with a patent granted in 1979. Today, Dyneema is used in numerous industries with diverse applications, but the Dyneema Project is specifically focused on its use in apparel.
In conclusion, Dyneema has evolved from being a material used in specialized outdoor gear to a fabric with broader applications in the apparel industry, as showcased in the Dyneema Project's collaborations with major brands. The article provides a glimpse into the history, current applications, and future possibilities of Dyneema in the realm of adventure travel and outdoor exploration.
