Fantastic. You warmed up as soon as you put it on and you barely noticed you had a jacket on, it was that light-weight!

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...

Still the same warmth, still the same box-wall construction protected by a windproof water-shedding outer, just as it was in the original Yukon race jacket used in temperatures down to -30°C.* But at 365gm this K Series Yukon is 20% lighter and will pack down that much smaller.

Our lightest and finest materials, 1000 down, 10X inner fabric and windproof water-resistant Ultrashell outer, along with lightweight (No.3) zips have taken this wonderful jacket to a new level of lightweight performance.

This is not designed as a high mountain jacket like the Hispar or the Xero. But when the kit has to be ultralight and stitch-through jackets are just not warm enough, the Yukon can be the ideal choice.

*Note Temperature rating. Race competitors balance comfort against weight by a different scale to most other people. The Typical Operating Temperature (TOT) of -15°C is the NORMAL rating for this jacket, while -30°C is the racers' rating.

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 Yukon jacket - K series - was fantastic. You warmed up as soon as you put it on and you barely noticed you had a jacket on, it was that light-weight! It stashed to virtually nothing in the small stash bag, which meant that I could easily put it in my day rucksack with water, cameras, other clothing without it taking up too much space. As soon as we got in to camp, the jackets went straight on to make sure we did not get too cold standing around. The whole package was excellent - good, roomy pockets, easy to use zip and a very warm hood. It was a real saviour."
Graham Brothwood, 9 day camping trip to Langtang Valley (Nepal) up to 3,840 metres.

"The Yukon is very light and the down fill is the softest I've ever felt, I haven't found one single shaft or barb inside the baffles of the jacket. The Yukon's hood … sits there perfectly and doesn't slip back or forward when I'm moving. It's so light and soft it might feel fragile in your hands but this a proper winter mountain jacket all the way."
Peter Macfarlane (PTC) review in WalkHighlands.

"I am sure that you will be interested to hear that our blue Yukon jackets fitted perfectly and kept us warm and snug in the Arctic snow. The jackets were the envy of everyone on board - praise indeed from such experienced travellers."
Nigel Humphries.

The comments below relate to standard Yukon Down Jacket, which is 95g heavier

"Many thanks for the jacket that you supplied me for the Yukon Arctic Ultra. [It] performed perfectly in temperatures down to -35c. The light weight and small size was also a huge help and helped me gain second place in the race. I ... am now the second fastest person over the course and the fastest European."
Dr Stuart Gillet (wearing a prototype Yukon jacket).

"Without PHD kit I would have been toast."
Jacob Hastrup 2nd place in Yukon Arctic Ultra 100 mile race.

"I'm always proud when I tell mountain guides and our guests about PHD and about the origin of my down clothing. The Yukon Down Pullover was been my best buy ever. In avalanche training courses it was possible to wear the pullover the whole day at -20 degrees Celsius!"
André Henzen, UIAGM Mountain Guide, Switzerland

"I used a Yukon down jacket with Gore-tex outer on the expedition. It packs down small (half the size of my previous jacket), it's great for early starts and when the snow starts falling."
Dominic Southgate - Imperial College Reru Valley Expedition (Zanskar Himalaya, India).

"For more serious winter outings I use PHD's Yukon Down Jackets. PHD make the best lightweight kit on the market. I just wouldn't go Munro bagging in winter without mine. It's fab."
Phil Newby.

"Ben was impressed with the Yukon Jacket I bought for him. In fact, we ended up fighting over it on more than one occasion! Again, simplicity of design, total warmth, amazing lightness and quality of manufacture was what made it stand out from the rest."
James Garrett.

"Thank you for the Yukon jacket! It fits super, is warm and nicely made."
Mark van Onna.

"Just wanted to thank you for the prompt delivery of my Yukon down jacket. It is fantastic and I have worn it constantly since it arrived."
Lise Cooper.
