Description

This jacket is now also available in custom sizesSpecify Body Width, Body Length, and Arm Length independently to order a made-to-measure down jacket. This tailor-made service can cope with sizes from XXXS to XXXL and is ideal if your chest/waist to height and/or arm ratios differ 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 Jacket. With box-walls, expedition-style pockets inside and out, a voluminous hood and many other features, the 'K Series' Xero Down Jacket has full expedition capability at minimal weight and packed size. Designed to provide exactly what is required on rapid high altitude ascents or lightweight arctic travel for expeditions. Suitable for those who are opting for the versatility of separate down garments over one piece suits. Insulation level is similar to the Xero Down Suit with the Standard fill.

Please note: If you order a custom-sized version of this jacket it will take longer (approximately 45 days) to be manufactured ready for dispatch. Custom-sized versions of this jacket 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.

Notes:

  • Down Jackets are sized to fit over thermal underwear & fleece.
  • Shell Jackets are sized to fit over thermal underwear & fleece or light down clothing (e.g. Minimus Jacket): to cover thick down clothing, go up one size.
  • The arms of our outdoor jackets are designed to be long enough to keep your wrists warm when your arms are extended horizontally (when using trekking poles, for example) or when you are reaching above yourself (when climbing, for example). In this respect the arm lengths of our jackets differ from street/fashion jackets.

Reviews

"Peter Hutchinson makes probably the best down gear in the world and his Xero jacket has kept me happy (well as much as you can expect to be) deep into the minus 40 degrees."
Nick Lewis, Climb Magazine.

"My Xero Jacket was back out in force this summer on two trips to Mt Elbrus. It performed superbly and kept me toasty warm despite the conditions."
Adele Pennington.

"Just a quick note to thank you for the timely supply of the PHD down gear before my Mt Vinson trip. The gear was absolutely first class. I used the Xero 900 down jacket on our summit day which was -26C with a 30-40 knot wind and they were faultless."
Mark Dixon.

"I've just returned from Vinson in Antarctica where your Xero down jacket made life a breeze."
Lord Forsyth, former Secretary of State for Scotland.

"Just a quick note to let you know that ALL 5 members of our team reached the Summit of Cho Oyo (8201m). Another member of the team wore [your] Xero Down Jacket and ... was comfortable and impressed. Thanks for the great gear."
'Lanx', Equipment buyer, UK Reserve Forces Seven Summits team.

"The Xero jacket was perfect for summit day where we had a combination of -25C and 20 knot winds and the thigh-length design meant that I never needed to wear the Xero trousers. It is the best down jacket I've ever used."
Nick Lewis, Antarctic Logistics and Expeditions.

"Very happy to report that the Xero Jacket performed fantastically and kept us warm and safe especially during summit day where temperatures dropped below -30 deg C."
Robert Gatt, Challenge8000, on Cho Oyu.

"Just a short note to thank you for making my Xero down jacket in super quick time. I am over the moon with it. What a pleasure to buy from committed experts. Never again the usual naff US brands where everyone knows they are made to far eastern specifications, in other words as cheaply as possible. I am still grinning."
P.S.

"Many thanks for the Xero Jacket for Cho Oyu which worked very well."
J.P.
