Description

These down trousers/pants are now also available in custom sizesSpecify Waist and Inside Leg sizes independently to order made-to-measure down trousers/pants. This tailor-made service can cope with sizes from XXXS to XXXL and is ideal if your waist to inside leg ratio differs from standard, ready-to-wear patterns. 


This K Series product has been created for one single reason, to take warmth-for-weight performance to the limit of what's possible. Unique 1000 down, super-light materials, and specific design features mean that the word Ultralight now applies to this wide range of gear that will take you to the Poles as well as on a Sahara Marathon. More on the K Series...

An even lighter version of our Xero trousers. Designed for fast moving expeditions to the highest levels or for any extreme cold weather venture where weight is at a premium. These down trousers use a highly efficient lightweight construction and provide an efficient hassle-free alternative when the full warmth (and weight) of salopettes is unnecessary.

Please note: If you order a custom-sized version of these trousers they will take longer (approximately 45 days) to be manufactured ready for dispatch. Custom-sized versions of these trousers are not returnable and customer loyalty discount cannot be applied.

Technical

Ultrashell (weight: 40gsm)

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.

Ultralight 10X fabric (weight: 26 gsm)

10X, PHD's First 10 Denier Fabric. 9,000 metres of the yarn used to weave 10X weighs just 10g, that's about the same as a £1 coin! For all its thinness 10X is amazingly downproof and with reasonable care will go on giving you good service for years.

1000 Fillpower Down

This rarest of all downs we reserve for the K Series. European goose down of unique quality. 1000 provides the highest warmth-for-weight performance possible from down. More on our down insulation.

Waterproof HS2 outer fabric (weight: 88 gsm)

HS2 is PHD's high-spec 2-layer ripstop for waterproof outers on our down. It is light enough to be the optional taped shell on our sleeping bags and tough enough for expedition use in our Omega clothing. HS2 is completely waterproof (when the seams are taped) and offers excellent breathability.
