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.

High performance mountaineering trousers. Rated at -20ºC these trousers are ideal for 6000m peaks and high altitude trekking expeditions. Filled with exceptional 950 fill-power down, and made in our lightweight water resistant Ultrashell fabric, the full-length side zips and the added protection of waterproof HS2 on the knee and the seat make for a robust and superlight package.

Ultrashell (weight: 40 gsm)

One of the lightest of PHD's coated materials. This ripstop nylon provides complete wind block and good water resistance at minimal weight. Ultrashell gives an excellent upgrade to performance with very little weight penalty.

Superlight MX fabric (weight: 32 gsm)

A mini-ripstop nylon with excellent tear strength, MX is the pick of the superfine 15 denier downproof materials. We have tested lighter fabrics, but most have had significant drawbacks, while our confidence in MX is based on several years of extensive use in both our ultralight and our high mountain gear.

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.

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).

"Using PHD gear has been a voyage of discovery for me, lighter than anything else I've used."
— Peter McFarlane, a.k.a 'Petesy'

"PHD are at the forefront of down clothing technology. I researched long and hard before deciding what to buy, and this firm is world class."
— Lord Forsyth, former Secretary of State for Scotland.
