Description

All-year-round performance from your Ultralight gear.

Overbags – sleeping bags sized and shaped to fit over standard bags to increase warmth – have been a firm favourite of PHD's clients from the start. They were in fact the innovative start point for our Sleep-Systems framework and kicked off a new approach to layering up of down gear to sleep in. Now, the latest development in lightweight fabrics has drawn us back to take a close look once more at the full potential of a combination system.

As well as offering the Superlight Combi here, we are offering the SuperLight Overbag on its own. This is cut wide enough to go over our DYO Superlight, Ultra, Minimus and Minim 400 sleeping bags, boosting their performance by 20°C.

  • Ultra: +8°C temperature rating. With the Superlight Overbag: -12°C
  • Minimus: +5°C temperature rating. With the Superlight Overbag: -15°C
  • Minim 400: -5°C temperature rating. With the Superlight Overbag: -25°C

Used alone, the Superlight Overbag is a wide bag with a Typical Operating Temperature (TOT) of 0°C, but consider its greater flexibility. In summer just pack your light innerbag, in autumn and spring pack just the overbag, and in winter – or in variable and unpredictable conditions – take both bags.

Just saying:  What about adding this Superlight Overbag to our new Triobag? 480g + 490g = total weight: 970g! A -25°C setup at under a kilo, and a vast range of potential TOTs and uses:  +15°C, +5°C, 0°C, -5°C & -25°C.

The inspiration for the Superlight Combi set – from which this Overbag was taken – was the new Superlight bags in our “Design Your Own Sleeping Bag” range. The DYO Sleeping Bag website allows a huge amount of customisation so you can have the perfect sleeping bag made for you.

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.

Water-resistant HyperShell fabric (weight: 28 gsm)

HyperShell is PHD’s exceptionally lightweight waterproof coated fabric. This remarkable ripstop nylon provides complete windblock and good water resistance at a breath-taking weight (28 g/sm). HyperShell protects the down from condensation drips found typically in tents, tarps and snow-holes, but its very low weight allows greater lofting of the down and a smaller pack size. Hydrostatic head: 1000mm.

Note: unlike some other so-called 'proofed' fabrics, HyperShell does not rely solely on a DWR (durable water repellent) coating. Although it has a DWR coating, more importantly it has a breathable and permanent PU coating applied on the underside of the fabric that cannot be abraded through daily use, so performance is maintained over many years.

Fabric weight: 28g/m2.

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 about 85gm (3oz) lighter than the full version.
  • Our full briefing on sleeping bag zips.

1000 Fillpower Down

This rarest of all downs we reserve for the K Series. European goose down of unique quality. 1000 provides the highest warmth-for-weight performance possible from down. More on our down insulation.

Construction

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

Feedback on our standard Overbag, which is 300g heavier:

"The fit is very good, no crushing of the inner bag ... and the loft is very good ... the Overbag + Minim has been a revelation. Warm enough for me to abandon all clothing bar my coating of 190 weight merino, and although slim cut, I don't feel restricted in it. The two bags interact very well, there is no sensation of multiple layers ... The two bags feel like one, but it's somehow cosier. I dare say it's one of those things that you have to try, but I have to say I have been warm, comfortable even delighted using these bags ... I think it's good to look at the two bags as a system and as individual bits of kit. That way it does kinda cover the whole year, does that mean it's all you need?"
Peter McFarlane, a.k.a Petesy, using PHD Overbag with a PHD Ultra.

"No one I know goes hiking in a big thick woolly jumper, so applying the layering principle to sleeping bags makes as much sense as it does for clothing. This past summer I used the PHD Minimus and PHD Down Overbag.

Immediately the benefits became obvious. Two smaller bags took up about the same space as my old bag, but were considerably easier to pack into dry bags each morning. Stowing them in separate compartments reduced the chance of them both getting wet and made packing the kayak much easier with less wasted space.

On occasions when conditions were [warmer] the inner bag was more than sufficient on its own – at these times I didn't even unpack the second bag from the kayak, thus saving time and energy the following day. Being able to slide either the inner bag down round your legs or the outer bag off made regulating your temperature easy on warmer nights.

It's now so obvious - I can’t believe it's taken me 30 years to apply this layering principle to my sleeping system."
Martin Rickard, www.seakayakadventures.co.uk

"I have a long-held belief in the 'layering principle' extending into sleeping bags. PHD's bags suit a multitude of adventure activity situations including:

  • Expedition sea kayaking
  • Himalayan style trekking where you travel through a wide range of temperature zones
  • Cycle touring where there is a similar packing issue to sea kayaking and potential for travelling through temperature zones
  • Plus, anyone who needs to use their sleeping bag across seasons. E.g. Just 'layer up' to convert your summer bag into a 'winter warmer'
During recent sea kayak expeditions in Greenland, my PHD Overbag, Filler bags were tested in temperatures ranging from just above freezing to as low as -10°C. It is a pleasure, when you know the temperature is dropping, just to slip into another bag and double the warmth factor"
