Description:

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...

In line with the rest of the K Series this Hispar Suit is pushing the boundaries. A down suit for 7000m weighing just 1105 gm? Desirable, yes. But is it possible? Yes again. 1000 down, Ultrashell outer fabric and 10X inner are the foundation for this extraordinary suit, making it possible to include all the essential features for a high mountain expedition in such a light piece of gear.

Full box-wall construction with 6 pockets above harness level, a generous helmet hood with a wired peak, a rainbow toilet system, crampon patches, articulated knees and elbows, they're all there and lots more besides. In fact everything's there except the weight.

Toilet access on suits

  • Under & Up zip: The central front zip on the suit runs from the collar, down the front of the body, past the groin and then under and up to waist level at the back. A two-way zip allows access at any place.
  • Rainbow Seat zip: A rainbow / semicircle zip is sewn in across the backside. A two-way zip allows access and creates a drop down flap.
More on toilet access.

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.

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 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).

"This is a very special suit. I lived in this suit for five continuous days on my Lhtose expedition (where I became the first British woman to summit more than four 8000m peaks). I was so happy with it, no problem accessing anything!"
