Our lightest sub-zero down vest, 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 vest weighs just 185g (6.5oz). 

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

£91 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.

Phil Newby, registered BAIML International Mountain Leader.

"I bought an ultra down vest from you a couple of months ago and used it at Easter when I was camping in the Cairngorm's. I was really impressed how light and yet warm it was, despite the temperature dropping to -10 overnight and there being a couple of foot of snow!"
John H.

"Just got my Ultra Vest. I wanted to say a big 'thank you' for designing such a fantastic piece of kit. It just felt 'right' as soon as I took it out of the parcel. I put it on (on this chilly July morning ...) and I felt immediately warmer. It is the most astonishing piece of kit I've ever owned (and I have an awful lot of stuff, let me tell ya). Beautifully designed, perfectly executed (not a stitch out of place). It's just breathtaking."

"So small and light that you cannot possibly not have it with you at all times! It is comfy and, when, at first I put it on I could not believe that it would keep me warm. How wrong I was. It is unnoticeable as a physical layer but highly noticeable as a warm layer. Peter Hutchinson has become a god of light and warm clothing in my book."
Jeremy Hastings, Islay Bushcraft.

"I've been meaning to write to say what a tremendous bit of kit this Ultra vest is. I have to say the warmth to weight ratio is sensational. Top quality bit of outdoor clothing and it's been a pleasure to deal with your company."
Mark H.

"Thanks for the Ultra vest ... a really amazing piece of kit. This must be pretty much the best warmth/weight ratio insulation piece in the world. I was glad to see your quoted weight matched the actual weights precisely. This garment is set to become an instant classic."
Alex Haxeltine.

"Just a quick note to say I have just completed the Marathon des Sables and found your new ultravest to be the perfect wear for the colder mornings."
John Moorhouse.

"I couldn't believe the warmth to weight performance of that little beauty [the Ultra Down Vest]. It fitted my requirements perfectly. Many thanks and congratulations on making such fantastic products."
Edward Fowler.

"Stuffs tiny. I'm wearing it now as the heating is being weird, lovely and warm and silky."
'Kesh' on Live for the Outdoors forum.

"I am so pleased with it! Tested that very evening ... I was like toast, and again the vest came up trumps whilst out in the woods last weekend. Once again thank you very much for a superb bit of kit!"
Andrew Jones.

"In a way it's a shame that the Ultra vest is as nice as it is! In the interim I'd ordered myself a Mountain Hardwear Below Zero jacket but I'm afraid that it feels second rate compared to the PHD vest. I fear that I'm going to have to return the MH and get myself a Hispar!"

"Ultra Vest arrived today. It is a sensational product. Thank you for it. It was worth waiting for. Please thank the artist who made it for me!"
Adam from Hobart, Tasmania.
