The sensation of immediate warmth is unsurpassed. The 1000-fill is so high-lofting, it puffs up as if a pump has been attached. Rare and wonderful.

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...

1000 down and 10X inner, the exceptional lightweight components of the K Series, have allowed us to make a down jacket at 240gm (8oz) which weighs less than most down vests. But make no mistake, this Ultra Jacket is a piece of real outdoor kit: the 1000 down gives surprising warmth inside the highly water-resistant and windproof Ultrashell outer.

It shares the pared-down design principles of the whole Ultra range: elastic at side-waist, light Lycra cuffs, waist-level front pockets, zipped inner security pocket, and a drop-tail back.

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. Order samples of this fabric & just pay the postage.

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. Order samples of this fabric & just pay the postage.

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 clothing sizing chart

Weight shown is for medium (M) size.

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 and Inside Leg from crutch to ankle bone. If you find that you fall between (or across) these sizings, please contact us and we will quote you for modifications needed. Modifications cannot be made to sale items, bargain box items or other products not offered at full price. And if you are supplying us with your measurements, it is always useful for us to know your height, even when you are only buying a jacket.

Reviews

"The sensation of immediate warmth is unsurpassed. The 1000-fill is so high-lofting, it puffs up as if a pump has been attached; this is enhanced by wide baffles, which allow the down to expand so quickly. Weight is kept to a minimum through simple but effective design. Overall it was a dream to wear. PHD is the only company in the world using 1000-fillpower down in clothing and sleeping bags for expeditions and mountaineering: rare, indeed, and wonderful."
