Features

  • Primaloft Gold® synthetic insulation (133gsm quality in body / 100gsm in sleeves)
  • Waterproof / Breathable HS2 outer fabric*
  • Breathable ripstop superlight MX inner fabric
  • Integral hood with wired peak, sized for a modern climber's helmet
  • Shoulder seams taped*****
  • Front closure: short zip + baffle with wide easy-hit Velcro.
  • Insulated storm baffle with stud at bottom.
  • 4 pockets
    • 2 zipped handwarmer pockets above harness level
    • 1 internal zipped security pocket with key hook
    • 1 internal zipped poacher's pocket for mitts
  • Reflector tape on front and back for night location
  • Clip loop to secure jacket at change-overs
  • Double exit adjustable hem cord
  • Side Stitched for maximum loft
  • Cuffs; simple Velcro closure
  • Beard flap
  • 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

The Alpha is a lightweight synthetic belay jacket for Scotland or the Alps. This is a mountain jacket, not simply a rock-climbers' warm-up item. Of course it will do that job, but you'll be leaving more than half its potential unexplored: the Alpha shows its true worth in unfriendly weather. Like the Zeta it is cut wide to fit over any other kit you are wearing and it shares the same hood and pockets as well as the other technical features which make PHD's belay jackets special.

With 133grm/m Primaloft Gold® insulation, this jacket gives reassuring protection in rough conditions. In our experience Primaloft Gold® absorbs water much more slowly than other waddings, a marked advantage in wet-cold conditions. The Alpha Belay can be worn all day over a fleece layer or equally be used over a hardshell jacket. The Alpha Belay Jacket could be used to provide additional warmth between cold belays by swapping between climbers at pitch change-overs.

The Zeta is a warmer version of this jacket, for temperatures around -20°C.

Please note: this jacket is designed and sized to be worn over top / outer layers. It provides additional warmth on cold belays and, typically, is swapped between climbers at pitch change-overs.

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.

Sizing

Standard clothing sizing chart

Weight shown is for medium (M) size.

The PHD Sizing Chart below is based on measurements without clothing, exactly the way you would buy a shirt, a sweater or a pair of trousers. A 42" (107cm) chest means that your bare chest uninflated measures 42". Inside Arm is measured from armpit to wrist-bone and Inside Leg from crutch to ankle bone. If you find that you fall between (or across) these sizings, please contact us and we will quote you for modifications needed. Modifications cannot be made to sale items, bargain box items or other products not offered at full price. And if you are supplying us with your measurements, it is always useful for us to know your height, even when you are only buying a jacket.
