This full-on expedition bag utilizes construction techniques and patterns from our lightweight mountaineering Hispar range and shares the same Ultrashell outer as our 'K Series' version. It has a lightweight M1 inner, and uses our superb 900 fillpower down. A half length zip with double draft tube keeps the weight down (a full length zip is available as an option). A mummy hood and down filled collar maximize the performance and Ultrashell panels have been added to the inner head and foot areas to cope with damp.

The PHD Hispar High Mountain Camp bag has a typical operating temperature of -35°C, which makes it an ideal choice for Himalayan mountaineering in the 7000m peaks.

Made to order and by hand, this bag comes with Short, Standard and Long Length options, as well as Slim, Standard and Wide Width option, so you get the perfect fit and the best possible warmth to weight ratio. And, as we are making these sleeping bags to order, you can select either Short or Full-length side-zips on the left or right sides.

£234 off standard pricing.

Dispatch time: As with all PHD products, these are made to order and by hand. We estimate it will take us around 4 to 6 weeks to make and dispatch sale orders. During busy periods it may take a little longer.

Ultrashell (weight: 40 gsm)

One of the lightest of PHD's coated materials. This ripstop nylon provides complete wind block and good water resistance at minimal weight. Ultrashell gives an excellent upgrade to performance with very little weight penalty.

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.

Sleeping bag zips

  • No zip: The standard design on our lightest bags with open hoods. The simplest/lightest system which is a must for adventure racers. Up to 140gm (5oz) lighter than a full zip with draft tube.
  • Full zips: Full zip bags ventilate well, so they can be used over a wider range of temperatures.
  • Short zips: Short zips are lighter and pack smaller than full zips. A short zip & draft tube is up to 85gm (3oz) lighter than the full version.
  • Our full briefing on sleeping bag zips.

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.


This bag has an insulating straight wall baffle system throughout (no straight-through stitching). Straight wall is the lightest of all baffle systems. In cross section it looks like this:

Side V channels, and double draft tubes behind the zip optimise insulation.

More on sleeping bag construction.

Proofed inner panels

Proofed fabric (Drishell or Ultrashell) panels are included inside the hood and foot areas of the bag to help keep the down dry. In very cold temperatures your breath can cause ice to form around the face opening, which may soak into the down as it melts. The panels at the foot end are to protect the down if you get into your bag with wet socks (or in extreme situations with your boots on).

"The bag has been excellent; I've taken it on a couple of expeditions. It's main use was on my Peak Lenin expedition. A lot of my teammates were using two bags, but the High Mountain Camp Bag was light enough so I could take it up on rotations and carry it back down after long summit day, whilst still having enough room for everything else. Despite some pretty cold nights up there, I was always warm on the mountain. I would have no hesitation in recommending it to others. Keep up the good work!"
