Description:

Our lightest-ever insulated jacket

A super-light down jacket with exceptional summer race and trekking performance.  At just 150gr (20% less than last year's version) it weighs less than many baselayers, and it packs down tiny taking the absolute minimum space up in a summer rucksack. 

The amazing 7X inner and outer fabric is our lightest-ever material and its sheer lightness enhances the performance and lofting of the unique 1000 Down insulation.

  • Ideal companion for summer nights
  • Pack without noticing the weight or bulk
  • Outer layer or mid-layer warmth
  • Warmer, lighter, and small pack size than a fleece jacket and 100% windblock too.

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.

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.


"At a whisker under 150g, the SumerLite is lighter than micro-baffled equivalents like MHW's Ghost Whisperer, but the combination of 1000 down (pretty much as lofty as you can naturally get down to be) and larger baffles - technically down channels - means it feels significantly warmer. It gives proper instant down warmth after you extract it from a package that's little bigger than a largish apple. And of course it's windproof too.

At a weight that's less than half of a typical fleece jacket, but with loads more insulation value, it looks like a brilliant option for portable, packable warmth for stops and evening campsite or hut use.

Phenomenal warmth for the weight and bulk."

The reviews below relate to 2015 version, which was 30g heavier

"Unlike most jackets this light, it uses relatively large baffles to house its ridiculously high-lofting, 1000 fill-power down, which in turn seems to make it significantly warmer than similar weight micro baffled jackets.

A stunningly light down jacket that gives instant and welcome warmth when you pop it on. Proper, down-type warmth rather than something like a micro fleece."

—OutdoorsMagic Review.

"I can't recommend this enough. An incredible product that is functional, packs small and is superlight.

I tested it 'in situ' at Richtersveld Wildrun in South Africa and at the Ultra Skymarathon, Madeira.

On first impressions it's difficult to believe that when one looks at it compressed in a small stuff sack it could possibly be a down jacket.

The inner fabric is silky smooth and a pleasure to wear against the skin. I wore the jacket with just a t-shirt underneath and found it really comfortable.

It may be light but it's warm, really warm. Let's be realistic, it's not for polar conditions. But if you need a warm layer to protect against morning or evening chill, daily colder or cooler temperatures or an additional warmth layer to be added under a Gore-Tex (or similar) or windproof jacket, it's the perfect choice.
Ian Corless, Talk Ultra Review.

"The lightest down jacket in the world, with a packed size about the same as a rolled up pair of walking socks. I loved mine, and never really head for the hills without it these days. The more I wear mine, the more I realise that it's better than carrying a fleece around in the summer."
