The Aigis was a shield carried by the ancient Greek gods Athena and Zeus, its literal translation is “violent storm”. Our latest waterproof trousers are designed to provide the ultimate protection from the elements through the use of uncompromising eVent® fabric technology.

A 20,000HH and 20,000gsm2 membrane makes for a highly waterproof and highly breathable pair of trousers, ideal for dynamic activities in wet and cold climates. 

Another unique benefit of eVent fabric is its mastery of Direct Venting™ technology – the work of billions of microscopic pores built into its membrane. This proprietary design allows instant venting of sweat from the inside of the trousers as you move and unlike conventional waterproof fabrics, it doesn’t need to get wet to work.

eVent’s Direct Venting™ technology is a dry system and will keep you well ventilated and comfortable across a wider range of environmental conditions than ordinary waterproofs. As a result, the Aigis Trousers make for some of the most dependable and versatile mountaineering trousers around.
