Minimus Down Socks/booties

The Minimus trousers and socks are amazing. The combination of weight, compressed volume and insulation properties is outstanding.



  • Exceptional 900 fill-power European Goose down
  • Lightweight M1 Fabric inner and outer
  • Box-wall down sole for maximum loft
  • Elasticated ankle
  • Stuff sac
  • Packed size 10 x 18cm*
  • Colour: Black

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


  • Ensure warm feet inside your ultralight sleeping bag.
  • Extra warmth inside cold tents.
  • A little extra for mountain bivouacs at any altitude.
  • Packed at 10 x 18cm (and squashable) they'll fit anywhere in your sac.

The 'comfort-value' of this tiny package is out of proportion to its weight.

Lightweight M1 fabric (weight: 39 gsm)

Lightweight silky microfibre. This close-weave 20 denier fabric is fully downproof, but also light and flexible enough to allow the down full loft. A reliable performer that has been the basis for much of our lightweight gear for some time.

900 Fillpower Down

European goose down of very high quality. A truly excellent down with large clusters, consistent quality and lively long-term performance. More on our down insulation.

"The socks were a wonderful little luxury to put on when the walking boots came off. They even got used as emergency mitts when we got called out during dinner for a snow leopard sighting!"
Wendy Matthews on a trek and snow leopard tracking expedition in Mongolia

"The socks are AMAZING and I am so delighted with them. Thanks and kind regards to all the team at PHD for your EPIC products."

"The Minimus trousers and socks are amazing. The combination of weight, compressed volume and insulation properties is outstanding. With down I was able to reduce my pack weight significantly."

"Thank you for the fantastic equipment. Everything (including the Minimus Down Socks) was above and beyond what was required and fended off the elements perfectly."
Graham B., on a trip to Aconcagua.

"The Minimus Trousers and Down Socks were absolutely brilliant! When I worked at the Everest Trail Race before I was a little cold, not this year! The trousers and socks made all the difference not only at night but in the day when standing at exposed peaks."
Ian Corless, Adventure Photographer.

"The solution to cold feet."
Mike Smith, on Trip to Greenland's 'North Liverpool Land', April/May.

"I'm currently in Wisconsin and your Minimus pants and socks are doing a great job of keeping me toasty in -14C!."
