Xero Down Suit: K Series
Fantastic ... felt toasty at -25C even when the wind picked up. It was a pleasure to live in them day and night.
Olga Kotova - using Xero down suit on Everest.
The PHD Sizing Chart below is based on measurements without clothing, exactly the way you would buy a shirt, a sweater or a pair of trousers. A 42" (107cm) chest means that your bare chest uninflated measures 42". Inside Arm is measured from armpit to wrist-bone. Inside leg is measured from crotch to ankle-bone.
Once you've selected a Body Width you can choose Body Length, Arm Length, and Inside Leg up to two sizes bigger or smaller. For example, a suit with a medium (M) Body Width can be XS, S, M, L, or XL in Body Length; XS, S, M, L, or XL in Arm Length; and XS, S, M, L, or XL in 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 Down Suit. The ideal lightweight suit for today's fast ascents. It has seen many summits on Everest and the other 8000m giants. The Xero suit has full expedition specifications, with box-wall construction, expedition-style pockets inside and out, a voluminous hood and many other features. Designed to provide incredible weather protection on rapid high-altitude ascents or lightweight polar expeditions.
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.

"I ordered a Xero down suit ... off you guys middle of last year. I used [it] on Cho Oyu and [it] worked fantastically ... I did put the gear through a thorough test and am totally happy with the way [it] performed."
— Ben Kane, Guide
"Just a quick note to let you know that ALL 5 members of our team reached the Summit of Cho Oyo (8201m). I wore my Xero Down suit with 800 fill on the summit day and [it was] fantastic, the temp was -25C on the summit with a brisk 20-25 knot westerly wind, and I remained cosy warm for the 13 hours it took to get from camp 2 (7200m) to the summit and back down to camp 2. Thanks for the great gear."
— 'Lanx', UK Reserve Forces Seven Summits team.
"One of the most practical one-piece 8,000-metre down suits available. With six pockets and internal braces reinforced in key wear areas ... Designed by the man who produced the legendary Annapurna duvet jacket, the wind and snowproof Xero sports the same box wall construction found in top flight sleeping bags. Fitted with articulated knees and arms for ease of movement."
