The OMM Aether Ms Jacket is an extremely durable, ultra-light and fully waterproof shell jacket , developed for mountain running, alpine environments and fast-and-light adventures where durability must not come at the expense of weight . Weighing only around 225 grams, the Aether delivers performance on par with heavy alpine shell jackets , but in a format suitable for high speed and long distances.

The jacket is constructed from Dyneema®-reinforced nylon , a material that is 15 times stronger than steel for its weight , but with a weight closer to silk. Used in everything from climbing harnesses and ballistic protection to boating gear , Dyneema gives the Aether exceptional resistance to tearing, abrasion and long-term wear . This makes it one of OMM’s most durable jackets – both in practice and from a lifecycle perspective.

The Aether Ms Jacket is built in a 3-layer construction , with:

a durable outer material in Dyneema/Nylon ,

a waterproof but highly breathable membrane ,

as well as a woven backer that keeps condensation away from the skin.

This construction provides significantly better comfort at high intensity compared to thinner 2-layer jackets often used in running.

With a 20,000 mm water column and 20,000 g/m² breathability, the jacket can withstand prolonged heavy rain, strong winds and intense exertion in exposed locations – from rain-swept moors to alpine ridges. At the same time , PFC-free DWR and a PFAS-free membrane are used, with Dyneema being made from recycled material and enabling recycling even at the end of the product’s life.

The fit is Active/Performance , with details tailored for running and movement in technical terrain: a fully adjustable, laminated and reinforced hood , extended dynamic droptail , integrated thumbholes , as well as high-positioned hand pockets that work with a backpack or harness.
