Xero Down Trousers: K Series
Your down trousers were lovely to wear in the hard wind outside the tent during our ski tour last week in the Swedish mountains.
Stefan & Susanne Grimfors.
The PHD Sizing Chart below is based on measurements without clothing, exactly the way you would buy a pair of trousers. Inside Leg is measured from crotch to ankle bone.
Once you've selected your Waist size you can specify the Inside Leg size up to two sizes bigger or smaller. For example, a trousers or salopettes with a medium (M) Waist can have XS, S, M, L, or XL Inside Leg. If you have any questions about your size, please contact us.
N.B. PHD clothing is unisex.
* Please note: we make our stuff sacs big enough to allow fairly easy stuffing rather than reducing clothing to the tightest minimum.
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.

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.
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.
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.
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.
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.
