Description

Camp down to -30°C and bivvy down to -40°C.*

Our extreme expedition half bag (pied d'elephant) to insulate legs and feet. Combine with suitable expedition down clothing to save weight and reduce pack-size. The use of pied d’elephant or Halfbags for lightweight bivis and camping is well proven in the mountains. Here we’ve added a neck length fabric “extender” to cocoon your body, arms and hands to reduce cold air ingress.

Half-bags are back

Half-bags (Pied d'elephant to oldies) are coming back. They've been out of fashion for many years in the trend towards using lifts and huts to make quick comfortable ascents, when a bivouac was a mistake, not a plan.

But the logic behind half-bags is still valid. If you're wearing a warm jacket already, all you need to spend the night out is something to keep your legs warm and there's no lighter way to do that than to use a half-bag. Check out the weights of PHD's half-bags and see for yourself.

  • Deep winter bivvying and snow-holing when paired with a suitable jacket
  • When you want a lightweight backup in case weather, miscalculation or accident catch you out

...A half-bag is the lightest answer.

*Note on Temperature Ratings

We have given two separate TOTs (Typical Operating Temperatures) for this half-bag.

  • 'Camp' is for the times people might want to use it for lightweight camping instead of taking a sleeping bag (an appropriate jacket and ground insulation is assumed): this is a standard TOT, meaning you should be able to get a good night's sleep under normal circumstances.
  • 'Bivvy' gives a range of temperatures from the usual doze level down to the point beyond which you're liable to be awake and getting cold. Again an insulated jacket is needed.

All these figures assume you are wearing normal clothing inside the half-bag. Any insulated kit like down trousers and down socks will improve the TOT. Don’t forget, the down jacket needs to be warm enough to sleep in.

Technical

Ultrashell (weight: 40gsm)

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. Order samples of this fabric & just pay the postage.

Superlight MX fabric (weight: 32 gsm)

A mini-ripstop nylon with excellent tear strength, MX is the pick of the superfine 15 denier downproof materials. We have tested lighter fabrics, but most have had significant drawbacks, while our confidence in MX is based on several years of extensive use in both our ultralight and our high mountain gear. Order samples of this fabric & just pay the postage.

950 Fillpower Down

A newcomer to our range. European goose of rare quality. A high value alternative at the top levels of performance. More on our down insulation.
