This looks amazing. I can see the Hispar bag working incredibly well up to 7000m in combination with the Hispar combi and a Hispar jacket.

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.

  • When there's no hut in the right place for your climb, or it's full, or you just don't like the crush
  • When you want to wander along your GR, free to sleep inside or under the stars as the fancy takes you
  • 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.

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.


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 light weight, small pack size and high insulation performance of the Hispar half bag make it a winner for anyone who brings a down jacket to camp. Those who like to bivvy will enjoy the flexibility of movement and lack of messing around with snagging zips. This bag comes with my highest recommendation."
