Description

Highly Commended TGO Magazine Gear of the Year Awards

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...

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. 


The Hispar jacket was originally designed to be the lightest down jacket you would think of taking up a 7000m peak. The K Series Hispar goes a step further. With the use of specialist new fabrics Ultrashell and 10X along with PHD's 1000 down we've made the lightest even lighter. This is still a fully capable high mountain jacket rated at -30°C with box walls, chest pockets, an internal water-bottle pocket, and a large helmet hood: but it weighs in at just 575gm. Wear it or pack it, you'll feel the benefit from the lightest piece of high-altitude kit available.

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.

Sizing

Standard Sizing

The PHD Sizing Chart below is based on measurements without clothing, exactly the way you would buy a shirt or a sweater. A 42" (107cm) chest means that your bare chest uninflated measures 42". Inside Arm is measured from armpit to wrist-bone.

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.

Highly Commended TGO Magazine Gear of the Year Awards

"This is a phenomenal jacket. I've never before come across one anything like this warm at this low a weight. I've also never come across 1000 fillpower down before. The design is excellent. The Velcro-closed hood is amazingly warm and the insulated pockets lie above a pack hipbelt. The Hispar K is longer than most insulated jackets too and has a waist drawcord as well as a hem one. If you want an incredibly warm jacket at the lowest possible weight this is the one."
Chris Townsend, Gear Editor, TGO Magazine. Read full review.

"The loft is just absolutely INSANE! Unbelievably lightweight! And unbelievably warm for the weight! It is the best down jacket I have ever seen and tried on."
Petar J Skundric

The comments below are for the standard Hispar Jacket, which is 150g heavier:

"For warmth the Hispar Jacket is the lightest I've used."
Tom Richardson in Climb Magazine.

"The Hispar is a totally amazing jacket. Really surprised by the warmth it offers. Amazing warmth to weight. Used it on 3 Aconcagua expeditions this season and it was just ideal."
Ben Kane, Guide, Field Touring Alpine.

"It came up the Moonflower with me and I bivied in about -20 degrees C in just the Hispar down jacket and a superlightweight bothy bag and that was fine. The kit is incredibly efficient weight vs warmth. The down that you use is just insane for lofting power."
Jonathan Griffith using the Hispar Jacket on the Moonflower Buttress in Alaska, USA.

"The Hispar Jacket and Hispar Sleeping 400 Bag arrived in California yesterday. I'm over the moon to say the least. The build quality is excellent. Consider me a totally satisfied customer, please pass my thanks on to the team."
Rory Abbott.

"The Hispar jacket has kept me warm in minus 30 C with a warm sweater and thick wool underwear, even when standing still for hours icefishing. So I am very happy with it."
Jeanette Lykkegard Nielsen using the Hispar Jacket studying reindeer headers on the Kamchatka peninsula, Siberia.

"The Hispar more than lived up to the sky high expectations and has delivered time and again. I've only worn it in minus 15C so far but even with just a base layer underneath I needed to have the zip halfway down to avoid meltdown! It is a wonderful piece of kit and is worth every penny."
Marcus P.

"My new Hispar jacket arrived this morning ... it's brilliant thanks and I'm delighted with it."
Rowan Huntley.

"Great down jacket from the English expert for down clothing, PHD."
Racelite.com

"Many thanks for rushing the Hispar down jacket through. I certainly needed it. The weather on Ama Dablam was settled but cold and I would have been stuffed if it wasn't for the jacket."
Tim Ralph.

"Thank you for the fantastic equipment. Everything (including the Hispar Down Jacket) was above and beyond what was required and fended off the elements perfectly."
Graham B., on a trip to Aconcagua.
