This limited edition Autumn Wafer Ultima Down Vest is £109 less than our standard Wafer Ultima K down vest. Although a little heavier (by just 30g) it boasts a water-resistant Ultrashell fabric outer, proofing the vest to a higher degree. Part of our Autumn Fast & Light Collection.

With Autumn’s lower temperatures comes more condensation, increasing the likelihood of damp gear inside and outside your tent. Like the rest of our Autumn Fast & Light Collection, this vest is ‘Autumnised’, built to repel damp and drizzle. At the same time it’s incredibly light, helping you travel fast.

It's designed with an eye towards mountain marathon racers, lightweight backpackers, bike-packers, multistage ultra runners, lightweight campers and wilderness trampers – but well suited to anybody who wishes to move fast and light.

Incredibly, it weighs less than a base layer and packs down into a teeny stuff sac. 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 145g/5oz weight!

This astonishing zero degree down top uses our water-resistant Ultrashell fabric to provide total windblock and help keep out the damp and drizzle. The rare 950 fill-power down ensure extremely weight-efficient insulation. This is a top to wear though, not just to weigh: added function comes from the full length zip, the hand warmer pockets, and the optional down filled hood.

Only available August and September. 

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.

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.

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.

Review is for our standard Wafer Vest which is 15g heavier

"I've used it a hell of a lot, both on the hills and in just about every other scenario I can think about. I find this a truly superb piece of kit.

There are two good hand warming pockets that have a generous capacity.

The vest is lovely and warm when zipped up. PHD rate this as useful down to zero but I think you'd be happy wearing this, perhaps, down to -5°C.

One of the main advantages of the Wafer Vest is that it is thin. This easily will slip under your shell jacket so that you can wear it while walking. I bought this jacket for extra warmth while moving not for extra warmth in camp and I think works very well for what I wanted it to do.

Wearing this vest under my jacket protects the down and adds little extra bulk. Although you want to keep down away from water down does wick steam and water vapour well. When working hard on the hill the vest is always very comfortable.

When the temperature begins to rise a simple opening of the front zip will loose a lot of heat. When completely un-zipped the jacket is so thin and light that you almost don’t realise you are wearing it.

The outer fabric of the vest is also very light but it doesn't seem too fragile and has coped well so far struggling through the usual woodland but remember this vest is designed to be worn under other protective layers. I am very, very, pleased with this purchase. At 190 grams it is always going to find a place in my pack for cool weather walking and backpacking."
