Clearance Aether Dyneema Jacket Waterproof Jackets

Jump to: Our Verdict / Features / Specifications

UOG TOP PICK: Built with mountain runners and fast packers in mind, the Aether Dyneema offers impressive protection for challenging conditions. It’s a dependable choice for those who require durability and functionality without the weight—a top pick for dedicated trail runners. 

OMM says: 

We’ve been tinkering away to create something that is (we think at least) very exciting. The Brief: To make the toughest running jacket we could.

Whether it’s taking on October weather for two days at The OMM, a midwinter traverse of the Pennine Way, or a fast-packing enchainment of alpine peaks, you want a jacket that protects you against the elements whilst maintaining a lightweight quality. Since these requirements are quite niche, but specific to our runners, we at OMM took on the challenge of developing a jacket that does just that.

Achieving this brief meant pushing fabric technologists towards even lighter and stronger solutions. Even lighter than our flagship jacket, the Kamleika, but with the same breathability and waterproofing, the Aether jacket is more of a feat of engineering than a running jacket. Working with industry-leading experts Dyneema, we have created a mountaineering spec jacket for less than 230g.

If you’ve not heard of Dyneema Ripstop before (only us gear geeks have), it is an Ultra High Molecular Weight Polyethylene (UHMWPE – now there’s an acronym) more commonly found in ballistic vests and climbing harnesses that boasts high tensile strength and abrasion resistance.

With strength x15 stronger than steel, the addition of Dyneema allows runners to take on gorse and heather, rocky outcrops, or just the wear and tear of pulling a jacket in and out of a pack.

Our Verdict

The OMM Aether Dyneema Jacket is a highly durable yet ultralight shell designed for rugged, high-intensity mountain activities. Weighing just 222 grams for the medium size, it effectively balances minimalism and resilience, thanks to its Dyneema-reinforced construction. Known for its exceptional strength, Dyneema is 15 times stronger than steel, making this jacket remarkably abrasion-resistant without unnecessary weight.

The Aether’s feature set is tailored for serious mountain use. The adjustable wired hood, full-length YKK Aquaguard zip, and dynamic drop-tail hem provide excellent weather protection, while the active cuffs with thumb loops keep it snug and in place. The two large chest pockets are vast and ideal for storing gloves, maps, or snacks within easy reach.

With a hydrostatic head of 20,000mm and a breathability rating of 20,000g/m², the Aether excels in keeping moisture out and managing perspiration. The jacket’s PFC-free DWR coating and PFAS-free membrane reflect OMM’s commitment to sustainability, which I appreciate as an added bonus.
