Just when you thought a sleeping bag couldn’t get any lighter …. The Delta-Race 100 K is the lightest bag PHD have ever made. And, at 200g, probably the lightest sleeping bag in the world. 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.
Using 18g/m2 Vertex fabric and 1000 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 100 K 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 because poor sizing compromises insulation, and you don’t want to carry excess material, do you?
The outer fabric can be upgraded in various ways:
- By replacing Vertex with our water-resistant Hypershell fabric. This helps deal with the condensation that can form on the inside of a tent or bivi.
- By adding a waterproof Dri-LX outer, which provides an extra seam-sealed outer shell to the bag. While a shelled sleeping bag is not designed to be used on its own in heavy rain (water will find its way in), the shell does protect the bag when it is used outdoors without a tent, for example in a snow-hole or under a tarp.
Furthermore, because touching the inside of a tent can cause dampness around the foot of sleeping bags, an optional waterproof foot cover can be added for extra protection. This can be sewn on or – so you can detach it and strip the bag right down for super-minimalist overnights – we can make it stud-on: it’s up to you. Note: there is no need for this foot cover if you have selected a waterproof Dri-LX outer.
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.
