Description:

The Delta-Race 200 is the lightest 4°C sleeping bag PHD have ever made. Created for self-support ultra-runners, elite mountain marathon racers, lightweight backpackers – anybody who demands every ounce of performance from the kit they carry. This whisper-light bag packs into a pocket-sized stuff sac, taking up a minuscule amount of space in your rucksack.

At just 310g, the Delta-Race 200 is the lightest bag that’s suitable for desert races such as the Marathon des Sables.

Using 18g/m2 Vertex fabric and 950 fillpower goose down (our rare, exceptionally high-grade insulation) allows us to create a superbly lightweight bag, and the specialist dual-construction design and neck length dimensions make this the most extreme example of its kind.

The top of the bag uses box-wall construction to allow optimum down lofting, and stitch-through construction on the base sheds excess bulk, working with your ground insulation mat to deliver the incredible weight saving performance. 

As with all PHD sleeping bags, the Delta-Race 200 is made to order, so we can offer plenty of options. To begin with, a combination of 4 different lengths and 4 different widths allows you to get the perfect fit. A perfect fit is important primarily because poor sizing compromises insulation, but it also means that you carry only what’s necessary.

Half- and full-length zip options allow greater flexibility in varying temperatures, while the foot-zip option is the ultra-light way to cool warm feet. Of course, to maintain minimum weight and pack size we’ve selected super-light zips.

For the midsummer months we're launching our Vertex Collection: the lightest Down Vest, Jacket, Shorts, and Sleeping Bags in their class. Only available May and June at never to be repeated prices.

Ultralight Vertex fabric (weight: 18 gsm)

Breathtakingly light at 18 gsm, Vertex is the ultimate in technical fabrics for extreme weight saving. This fabric is down-proof and superbly wind-proof and represents a high-point in the development of lightweight technical fabrics. The result of years of evolution and testing, this whisper-light fabric opens up new possibilities at the pinnacle of lightweight gear design

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.

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.

Construction

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

On the bottom stitch-through seams are used to minimise weight. More on sleeping bag construction.
