Down Clothing adds no pack-weight if you're already wearing it, and that’s true for a Minimus jacket in Scotland or a Xero suit on Makalu.

Clothing, Filler, or Overbag will add multiple options to your sleeping kit.
EASY STOWAGE
EASY STOWAGE
Sleep System items are small and stowable in contrast to one major sleeping bag which takes up most of your pack space.

Comfort and safety can be enhanced by a well-coordinated Sleep System, flexible enough to meet a variety of different situations.

New dimensions for an old idea

Smart lightweight campers have been using their clothes to boost the warmth of their sleeping bags for years and climbers do it when they have to. Yet most of us are still carrying bags much bulkier and heavier than we need.

Now PHD Sleep Systems opens a whole new level of possibilities. It links together the unique warmth/weight performance of all our down gear along with the new designs we have created specifically to expand the potential of this powerful idea.

Sleep Systems lays it all out for you, a clear universal framework that works for any night outdoors anywhere, covering the whole range from valley camping to top camp on an 8000 metre peak.

Take a look and see how you can do a great deal more with less.
