The material feels durable but soft and its ample dimensions made it a pleasure to wear ... Overall, a top notch jacket which does the job excellently.

Standard Sizing

The PHD Sizing Chart below is based on measurements without clothing, exactly the way you would buy a shirt or a sweater. A 42" (107cm) chest means that your bare chest uninflated measures 42". Inside Arm is measured from armpit to wrist-bone.

Size	Height	Chest	Waist	Inside arm
XS	155-163cm (5'1"–5'4")	86cm (34")	71cm (28")	46cm (18")

For example, a jacket with a medium (M) Body Width can be XS, S, M, L, or XL in Body Length and XS, S, M, L, or XL in Arm Length. If you have any questions about your size, please contact us.

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.

Description:

Also available in custom sizes. We make clothing to order, so if you’re not a standard size we can make it to fit. To order a non-standard custom size, select the Custom Sizing tab, choose your body width, and then the body/arm lengths, shorter or longer, that work for you. A custom size takes us a little longer (typically two weeks longer) to make and, because it’s personalized, it’s non-returnable and our customer loyalty scheme can’t be applied.

The Alpamayo Jacket is made with our HS3 3-layer fabric, lighter, more waterproof and more breathable than ever before. The two-way front zip is covered by a storm flap with Velcro closure to give maximum weatherproofing. The wired peak on the hood provides effective protection when closed down with or without a helmet. The cut is generous, to go over a lightweight down jacket such as the Minimus K or Yukon.

With two large chest pockets covered by waterproof YKK Aquaseal zips and good arm-lift this is a deliberately simple piece of kit designed for hassle-free use in action. A lightweight jacket, but one you can take with confidence into extreme situations.

Also available in a lighter 'smock' style.

Waterproof HS3 outer fabric (weight: 115 gsm)

HS3 is a 3-layer laminate, the new fabric for our Alpamayo shell gear. The old argument that a 2-layer fabric with a separate mesh inner was both more flexible and more breathable than a 3-layer has been overtaken by the performance of current 3-layers such as HS3. This new ripstop fabric also removes the disadvantages of mesh (which snags on velcro and can form an ice-trap in extreme cold) and makes the gear considerably lighter. HS3 is fully waterproof and offers excellent breathability.

YKK AquaSeal® zips

Successfully used for years on dry suits and marine sportswear, these AquaSeal® zips are the only fully waterproof zips we know light enough for clothing. No rain flaps are needed.

"The material feels durable but soft and its ample dimensions made it a pleasure to wear. Its waterproof (and windproof) qualities were first rate and tested to their fullest during a particularly unpleasant spell in the Alps weatherwise. The inside layer also feels like it isn't going to flake away as often happens. The hood is supported by a wire which makes it particularly useful when the going gets wet and windy ... Overall, a top notch jacket which does the job excellently, looks very smart."
— Mark Dodwell, UILMA Guide.

"A quick note to say thank you for the incredible kit I purchased from you a few months ago. I have recently returned from a research expedition in Antarctica and used the Alpamayo jacket on numerous occasions during shore landings and when caught in blizzards. It functioned perfectly as part of a multi-layer system and not once did my inner layers get wet - even after being caught in fairly aggressive weather out on the zodiacs. Have attached a picture from Port Charcot."
— Dr Nathan Smith, University of Northampton.

"I have just come back from Chile, where I climbed Ojos Del Salado, the highest active volcano in the world (6893m). [I was] wearing an Alpamayo jacket and salopettes ... All the equipment I bought from you worked fantastically well, and I have recommended your gear to anyone who will listen."
— R.M.

"I purchased one of your Alpamayo jackets a couple of years ago. I have been very impressed."
— Nick.
