Description:

Warmth while you sleep is essential; carrying extra weight isn’t.

Created for self-supported ultra-runners, mountain marathon racers, lightweight backpackers – anybody who demands every ounce of performance from the kit they carry – the M.Degree° bags form one of the lightest series in our range.

Using “7X” (one of our lightest fabrics) and 950 fillpower goose down (our unique, exceptionally high grade insulation) allows us to create a superbly lightweight bag, but it’s the specialist dual-construction design which takes it to the next level.

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

As with all PHD sleeping bags, the M.Degree° series is made to order, so we can offer plenty of options. To begin with, a combination of 3 different lengths and 3 different widths allow you to get the perfect fit. Primarily this is 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. Of course, to maintain minimum weight and pack size we’ve selected super-light zips.

Ultralight 7X fabric (weight: 22 gsm)

7X is our new sheer-light 7 denier fabric. An exquisitely fine rip-stop nylon, 7X is incredibly light, highly wind-resistant and has first-rate down proofing. This fabric helps us create the very lightest of gear in the PHD range. Of course the lighter the fabric the lighter the sleeping bag or down clothing, and the less space it takes up in your rucksack. This fabric is so light it actually helps to allow even greater lofting of the down too.

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.

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.
