Description

Designed with an eye towards adventure racers, lightweight backpackers and campers, and multistage ultra-runners – but well suited to anybody looking for the lightest possible insulation – the remarkable Wafer Ultima Pullover is even lighter and warmer than the hugely successful Wafer Jacket we based it on. Incredibly, it weighs less than a base layer and packs down small enough to fit in a pocket. The longer body length and higher collar work to cut cold air ingress making for even warmer performance. And that’s really not bad, when you consider the 155g/5oz weight!

This astonishing zero degree down top uses our super-light 7-denier 7X fabric to provide total windblock, combined with our unique 1000 fill-power down to deliver the most weight-efficient insulation: the highest warmth-for-weight performance possible. This is a top to wear though, not just to weigh: added function comes from the deep venting half-zip, the hand warmer thru-pockets, and the optional down filled hood.


Technical

Ultralight 7X fabric (weight: 22 gsm)

7X is our new sheer-light 7 denier fabric. An exquisitely fine rip-stop nylon, 7X is incredibly light, highly wind-resistant and has first-rate down proofing. This fabric helps us create the very lightest of gear in the PHD range. Of course the lighter the fabric the lighter the sleeping bag or down clothing, and the less space it takes up in your rucksack. This fabric is so light it actually helps to allow even greater lofting of the down too.

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.

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.

Reviews

Reviews are for our standard Wafer Down Jacket, which is 35g heavier

"This jacket is astonishing. It's the weight of a base layer but warmer than a thick fleece. For backpacking it's ideal. I've used it on my last three long-distance walks, and over an ultralight thin synthetic insulated top it's kept me warm down to -7°C. The low weight and warmth are due to the extremely high fill power down, the ultralight shell fabric, the ultralight zips and the minimalist design.

PHD's down comes from European birds that aren't live-plucked – PHD visits the producers. Most other materials and components are sourced in Europe too. The garment itself is made in the UK. The fabric is surprisingly durable – I haven’t ripped it yet. It's not designed to be worn under a pack without a shell over it, however. It lacks a hood, but a stud-on one can be added. I recommend it as it makes a big difference to the warmth. The two pockets are roomy and just usable when wearing a hipbelt, though the bottoms are cut off.

The Large size fits me comfortably worn over a thin synthetic insulated jacket or medium-weight fleece.

The cost is high but there’s nothing anywhere near this weight that provides this amount of warmth or packs down so well – it can be squashed into a small ball."
Chris Townsend, TGO Magazine

"Made in Britain, with all components coming from within Europe and stuffed with traceable down. All good stuff. Unfeasibly warm for something so light. Impressive manufacturing ethics. Score: 10/10"
Trail Running Magazine feature on 'Best Ethical Kit'..

"Seriously impressive warmth, premium-quality 1000FP down and ultra-light weight. If you want to stay warm, this is hard to beat."
Walk Magazine (Official Magazine of The Ramblers), 5/5 'Best in Test'.

"PHD's super-lightweight Wafer Down Jacket is a third less bulky than a fleece, offering superior standby warmth without taking up the space."
Wanderlust Magazine.

"Performed brilliantly. The hood was a great fit and tight enough to the face to keep off wind. Absolutely incredible warmth / weight ratio, could not be more impressed. Minimal packed bulk meant it could be kept in a rucksack pocket for easy access when temperatures dropped. I honestly cannot suggest improvement for this product."
Nikolas Bjelic on the Everest Base Camp Trail, Nepal.

"Offers perfect temperature control in almost every type of situation (between -5°C and +20°C)" Alex F-B.

"Absolutely love the warmth and weight! Amazing engineering!"
Peter Reiter.

"It's brilliant!"
Ian Gauntlett.

"There are cheaper down jackets, but none made in the UK and none that'll fit into your one litre cooking pot when not in use."
Singletrack Magazine, 'Recommended'.
