Description

At 130grams the WaferLite jacket is the lightest down jacket in the world

The combination of windproof 7X fabric (our lightest) and our unique 1000 down results in a wonderfully flexible layering piece with the highest warmth-for-weight performance possible from down. Packed into a tiny stuff sac, the K Series WaferLite jacket is simply breathtaking.

It’s less than a third the weight of a mid-weight fleece and warmer too (and don’t forget it's totally windproof).

This is not high-mountain gear, nor is it ideal for doing dirty car repairs (fleece has its uses). But for the pure gift of warmth from something you could literally stuff in your pocket it has no rivals.

The features list is short: it’s what’s not featured (such as pockets) that makes the Waferlite such an individual piece -- and ultimately the lightest possible down-filled jacket.

  • Ideal partner for WaferLite Trousers and Socks
  • Use to give a temperature boost to your sleep system
  • Pack without noticing the weight or bulk
  • Outer layer or mid-layer warmth
  • Warmer, lighter, and smaller pack-size than a fleece jacket and 100% windblock too

The WaferLite range are summer-camping super-lights that give real warmth around camp and can boost your sleep system. This WaferLite Jacket or the WaferLite Vest combined with the WaferLite Trousers and socks provide a comfortable sleep suit for use with sleeping bags and quilts.

Technical

Ultralight 7X fabric (weight: 22 gsm)

7X is our new sheer-light 7 denier fabric. An exquisitely fine rip-stop nylon, 7X is incredibly light, highly wind-resistant and has first-rate down proofing. This fabric helps us create the very lightest of gear in the PHD range. Of course the lighter the fabric the lighter the sleeping bag or down clothing, and the less space it takes up in your rucksack. This fabric is so light it actually helps to allow even greater lofting of the down too. Order samples of this fabric & just pay the postage.

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.

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.
