Get “All Year-Round” performance from your Ultralight Semi-rectangular bags.

Overbags (where one sleeping bag is used around another) have been a firm favourite of PHD’s clients from the start. They were the start-point for our Sleep Systems framework and kicked off a new approach to layering up of down gear to sleep in. As well as going over the top of your main bag, Overbags can be used on their own, resulting in a superbly versatile modular system to cover a huge range of temperatures.

The Greenlandic Overbag is cut wide enough to fit correctly over either the Icelandic or Greenlandic bags (allowing full lofting of the inner) to extend further the full potential of these roomy sleeping bags. Used this way, the Overbag adds a massive boost of 23°C warmth to the bag it covers.


  Typical Operating Temperatures
Inner bag Inner bag Inner bag + Greenlandic Overbag Greenlandic Overbag
Icelandic 200 +5°C -18°C -5°C
Icelandic 300 0°C -23°C -5°C​
Greenlandic 400 -5°C -28°C -5°C​


If ordinary mummy shaped sleeping bags don’t quite match up to your idea of comfort, our Greenlandic and Icelandic semi-rectangular bags may be just what you’re looking for. Side sleepers and those who appreciate plenty of manoeuvring space will find these roomy bags less claustrophobic, allowing the independent movement a restless sleeper prefers.

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.

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 sytems. In cross section it looks like this:
