Description

This K Series product has been created for one single reason, to take warmth-for-weight performance to the limit of what's possible. Unique 1000 down, super-light materials, and specific design features mean that the word Ultralight now applies to this wide range of gear that will take you to the Poles as well as on a Sahara Marathon. More on the K Series...

This jacket is now also available in custom sizesSpecify Body Width,  Body Length, and Arm Length independently to order a made-to-measure down jacket. This tailor-made service can cope with sizes from XXXS to XXXL and is ideal if your chest/waist to height and/or arm ratios differ from standard, ready-to-wear patterns. 


In the K Series the original Rondoy has been transformed into a streamlined big mountain jacket weighing less than 500gm. 1000 down ensures the -20°C rating, the Ultrashell outer is proof against wind and damp, and the soft 10X inner adds a touch of comfort.

Two hand-warmer pockets at the waist, one chest pocket for stashing and quick access to your camera, a helmet compatible hood, and adjustable Velcro cuffs make this an exceptionally high-specification mountaineering Jacket.

The result is a superb lightweight you can take into big mountains with confidence (and a light pack).

Please note: If you order a custom-sized version of this jacket it will take longer (approximately 45 days) to be manufactured ready for dispatch. Custom-sized versions of this jacket are not returnable and customer loyalty discount cannot be applied.

Technical

Ultrashell (weight: 40gsm)

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.

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

"Exceptional warmth to weight ratio. Fantastically rugged for the light weight. The down stays where it's supposed to, it lofts up quickly and after a 6 week expedition it still looks brand new despite rough ledge bivis and daily wear (no tear!)."
With Simon Smith on 6 week trip first ascending around the Tasilaq ford, East Greenland. Read Simon's full test report.

"Tweaked for this year with two waist-level hand-warmer pockets making it a little more versatile than it's harness-friendly predecessor. Good news for high altitude trekkers taking in the night sky from outside the tea house we reckon. There's also a new two-way main zip to allow for easier use with a climbing harness."
OutdoorsMagic Review

"I would like to thank all the great people at PHD who make this great jacket. Earlier this year I bought this jacket and used it last month in Nepal for an expedition. I reached the summit of Mera Peak 6461 meters and was comfortably warm with this jacket. Thanks again for the great work."
Denis Put

Comment below relates to the standard Rondoy jacket, which is 125g heavier

"The jackets were incredibly warm and light, equally suited to ensure we were warm when climbing and even when static, melting snow, in the advance camps."
