Description

This jacket is now also available in custom sizesSpecify Body Width and Body Length independently to order a made-to-measure Primaloft 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. 


With a combination of Primaloft Gold® insulation, our lightweight MX fabric, light zips, and a simple design, this synthetic-filled Jacket is the right piece of kit when it's going to be cold and damp.

In our experience the 100gsm Primaloft Gold® synthetic insulation absorbs water much more slowly than other synthetic waddings, a marked advantage in cold, wet conditions.

Optional Ultrashell Outer

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.

Shown with optional Burnt Orange Ultrashell outer fabric.

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.

Superlight MX fabric (weight: 32 gsm)

A mini-ripstop nylon with excellent tear strength, MX is the pick of the superfine 15 denier downproof materials. We have tested lighter fabrics, but most have had significant drawbacks, while our confidence in MX is based on several years of extensive use in both our ultralight and our high mountain gear.

Primaloft Gold®

Primaloft Gold® is the ideal microfibre insulation. Ultrafine fibres produce an insulating core that is incredibly soft, lightweight and water resistant. In our experience it absorbs water much more slowly than other waddings, a marked advantage in wet-cold conditions.

The nearest of the synthetics to the feel of down, yet tougher than you would expect. Primaloft Gold® offers the best warmth/weight performance in the Primaloft range

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

Some of these comments are for the Sigma pullover, which this Jacket replaces.

"Warm. Perfect fit. Arms even better fit. Total mobility. Instant loft like a down jacket. The Hood saved me from having to buy a down hat to sleep in. Quality stuff."
Tony Swallow.

"It's winter. Client is very, very cold despite wearing all her spare layers. Problem. I give her my PHD Sigma to put on. Client gets warm. No problem. Yours, thankful for the incredible performance from your nanogram gear."
Tony Halliwell (MIC).

"Very warm for its weight. Reasonably small pack size. The armholes are bound by lycra to give a close fit, as are the pockets. Small, but very nice detail."
Ross Evans on Outdoorsmagic Forum.

"Just a quick note to say after a month or so deciding which smock to buy, PHD, RAB etc. I plumbed for the Sigma and how happy I am with it. I can't wait to test it but if it performs as well as it looks and is made, which I'm sure it will, then I will be very happy."
R.E.

"The Sigma pullover has arrived, and like everything else I have had from you is excellent."
N.J.

"Not a query; rather a big thank you. Received today my Sigma pullover. Mightily impressed by the materials, build quality, light weight, compactness and elegantly simple design. I also have a Sigma vest in a larger size which fits into the top pocket of my rucksack and is so quick and easy to slip on at winter belays."
T.H.

"Many thanks for my Sigma pullover which arrived yesterday ... I have been unable to take it off this morning - walking across the fields in below freezing frosty conditions, then cycling into town to do some shopping. I have been toasty warm with just a shirt underneath, and it makes me feel like a million dollars. It is so well made and thought out - I have just discovered the zipped security pocket - what a brilliant touch! It was meant to be Christmas present from my wife - but she is away at the moment and I just couldn't wait to use it. A fantastic start to Christmas!"
C.D.

"Today I've received the Sigma jacket and I am very, very pleased with it - (roll on winter because this is so lightweight it's unbelievable)."
Tony.

"Thanks for the two Sigma Pullovers. The pullovers were Xmas presents, and went down very well. They wouldn't take them off!!"
