Features

  • Outer fabric: Waterproof / Breathable HS2 outer fabric* (with taped shoulder seams)
  • Inner Fabric: Breathable ripstop superlight MX
  • Primaloft Gold® synthetic insulation (133g/m weight in body and sleeves)
  • Shoulder seams taped
  • Front closure - 2 way YKK Aquaguard water-resistant zip with bottom locking stud
  • 3 insulated pockets:
    • 2 zipped waist level pockets
    • 1 zipped chest pocket
  • Integral hood with wired peak, sized for a modern climber's helmet:
    • Adjustable front cord with cord ends tethered inside the hood
    • Wired peak
    • Volume reducer on the back of the hood*****
  • Reflector tape on front and back for night location
  • Clip loop to secure jacket at change-overs
  • Double exit adjustable hem cord
  • The Primaloft filling is edge stitched only to allow maximum loft
  • Cuffs; simple Velcro closure, to go over or under gloves
  • Stuff sac
  • Pack size: 13 x 21cm**

 

*Please note: although the outer fabric is waterproof, only the shoulder stitch lines are taped. So, although the outer will shed a lot of rain and snow, in a heavy downpour water can penetrate the stitching. However, the Primaloft Gold® insulation retains much of its insulation if wet. As always in the mountains, if there is a possibility of prolonged rain, carry full specification waterproofs.

**Please note: We make our stuff sacs big enough to allow fairly easy stuffing rather than reducing the jacket to the tightest minimum.

Description

Part of PHD’s trio of synthetic filled Belay Jackets (the Epsilon, Alpha and Zeta, with TOT* ratings of -5°C /-10°C /-20°C respectively), these technical insulating tops are perfectly adapted to wild, wet, unforgiving conditions: typical Scottish winter, essentially. It doesn’t end there though: demanding routes in demanding conditions – whether on steep water ice, big mountain faces or classic mixed test-pieces – are where these jackets belong, and those conditions will be familiar to climbers throughout Scandinavia, the Alps, the Arctic and Patagonia.

Equally at home when climbing or on the belay ledge, if you choose to swap one jacket between two of you as you change over at belays, you’ll find the cut is roomy enough to fit over your outer layers. If you’re keeping it for yourself though and climbing in it all day, the fit is nevertheless trim and efficient: ideal for wearing under your harness.

Freedom of movement is essential for a climber’s jacket, and so of course is protection from the elements. The climber-specific fit, waterproof fabric (with taped shoulder seams), grown on hood, full length water-resistant zip, extra body length, and pocket locations make for a solid, dependable jacket which allows you to just get on with the task at hand. These features are repeated throughout the collection, and with different levels of warmth to choose from, these belay jackets prepare you for a vast range of winter climbing adventures.

The trio share the same feature list but have different thickness of Primaloft insulation:

Typical

Epsilon Belay100g/m2-5°C
Alpha Belay133g/m2-10°C
Zeta Belay200g/m2-20°C

 

In our experience Primaloft Gold® absorbs water much more slowly than other waddings, a marked advantage in wet-cold conditions. Effectively, if you can retain warm air in the insulation rather than it being replaced by cold water the garment will stay much warmer.

Please note: this jacket is designed and sized to be worn over top / outer layers. It provides additional warmth on cold belays and, can be swapped between climbers at pitch change-overs. If you want a trimmer more athletic fit select the next size down.

Technical

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. Order samples of this fabric & just pay the postage.

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

Waterproof HS2 outer fabric (weight: 88 gsm)

HS2 is PHD's high-spec 2-layer ripstop for waterproof outers on our down. It is light enough to be the optional taped shell on our sleeping bags and tough enough for expedition use in our Omega clothing. HS2 is completely waterproof (when the seams are taped) and offers excellent breathability. Order samples of this fabric & just pay the postage.
