Ether Monosuit

509 Ether Mono Suit is a versatile, non-insulated shell monosuit for demanding backcountry days. Whether you are snowmobiling, snowbiking, snowboarding or skiing, the Sympatex® membrane combines 45K waterproofing with 25K breathability to keep the weather out while allowing heat and moisture to escape.

It is a practical one-piece choice for riders who value dependable weather protection, freedom of movement and well-considered details for long days in the snow. Full-length leg zips make changing easier with boots on, while adjustable ventilation, built-in knee protection and an internal harness help keep long, active days comfortable.

Why choose this product?

Choose the Ether Mono Suit if you prefer the complete coverage of a one-piece shell but want to control warmth with your own layering. Its combination of high breathability, adjustable ventilation and multi-sport design makes it particularly suitable for active days when both weather protection and heat management matter.
