Description:

Also available in custom sizes. We make clothing to order, so if you’re not a standard size we can make it to fit. To order a non-standard custom size, select the Custom Sizing tab and choose the waist and inside leg sizes that work for you. A custom size takes us a little longer (typically two weeks longer) to make and, because it’s personalized, it’s non-returnable and our customer loyalty scheme can’t be applied.

For complete weather protection these down trousers are made with waterproof HS2 fabric and fully taped outer shells. They provide an efficient hassle-free alternative when the full warmth (and weight) of salopettes is unnecessary.

HS2 has now replaced Tempest as the standard outer fabric for the Omega Trousers, making them lighter, more waterproof and more breathable than before. Tempest remains an option for trips where extra durability is the most important factor.

950 down option

This option adds 4°C to their performance bringing the Typical Operating Temperature to -59°C.

As used on The Coldest Journey on Earth

950 fillpower down

A newcomer to our range. European goose of rare quality. A high value alternative at the top levels of performance. More on our down insulation.

900 Fillpower Down

European goose down of very high quality. A truly excellent down with large clusters, consistent quality and lively long-term performance. More on our down insulation.

Waterproof HS2 outer fabric (weight: 88 gsm)

HS2 is a 2-layer laminate, a high-spec option for the outer layer of our insulated gear. This ripstop fabric strikes an excellent balance between lightness and durability. It is light enough for our Belay tops and tough enough for expedition use in our Omega clothing, while the Kappa clothing makes full use of both its qualities. HS2 is completely waterproof (when the seams are taped) and offers excellent breathability. (Weight: 88gsm).

Tough waterproof Tempest outer fabric (weight: 160 gsm)

A technically advanced waterproof breathable material. 100% Nylon. Good abrasion and tear resistance, yet offering high flexibility for such a tough material.
