Our lightest sub-zero down jacket, the Ultra, has always been a favourite with extra-keen lightweight backpackers and mountain racers. Now, at the start of winter, we’ve made this warmer version, with a typical operating temperature (TOT) of −10C.

Exceptional lightweight components—including 950 fillpower down—mean this jacket weighs just 280g (10oz). 

Despite its exceptional warmth-to-weight ratio, this jacket has a water-resistant Ultrashell fabric outer, elasticated side-waist, waist-level front pockets, a zipped inner security pocket, and a drop-tail back.

£126 off standard pricing.


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.

950 fillpower down

A newcomer to our range. European goose of rare quality. A high value alternative at the top levels of performance. More on our down insulation.

Reviews apply to the standard version of this jacket, which uses 1000 fillpower down

"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."

"Your kit is AMAZING !! Wow - very impressed. I'm a really cold person but even on my own in a tent at -8°C I was comfortably warm. It's also incredibly light. So light, the organisers made me take extra items to MAKE UP weight in my bag!"
Rebecca Ferry, using the Jacket in the Everest Trail Race, where she came in 4th in the women's race.
