PHD Ready Made Wafer Down K Series trousers review


Last updated: 27-Dec-18

By Alice Morrison

I had often heard of the mythical down trouser, a piece of kit so magical that it could save you from freezing your ass-ets off at even the lowest temperatures, so imagine my delight when the opportunity to try out a pair in suitably chilly (-10ºC) conditions arose.


  • PHD 'K Series': Ultimate warmth / weight performance
  • Insulation: PHD's Unique 1000 fillpower down
  • Outer & Inner fabric Ultralight 10X
  • Stitch-through for lightness
  • Adjustable shock cord at waist
  • Lycra edging at ankles
  • Weight 130g
  • Down to 0degrees
  • RRP £258

I am a medium-large woman but wore a small which fitted fine. I used them in camp at night on the semi self sufficient Everest Trail Race. This is what I found.


I almost cried when I packaged these up to return them to PHD as they were absolutely brilliant and I could do with them where I live now in the Atlas Mountains. They may have to go on the Christmas list.

Simply put, they are very light and very warm and helped me to recover every night as I just wasn’t cold, even when I was down to my most depleted.

Design 8/10
Features 8/10

Hi - I bought a pair of PHD down trousers during one of their sales, pre-K series stuff, but they are basically the same trousers. Mine have their own DWR outer, but otherwise the temperature rating is the same. I LOVE THEM! Living in the NW of Scotland means they get plenty of outings on my winter backpacks around the area, the Torridons to Fisherfield to Assynt and all points north. They are great in a mid-weight sleeping bag too, with an appropriate jacket, to reduce bag weight. Going outside in the night for star/borealis gazing without freezing yer bits off is a treat with warm legs, and also makes re-warming your sleeping bag that bit easier...
