Wafer Half Bag: 'K Series'
*Please note: We make our stuff sacs big enough to allow fairly easy stuffing rather than reducing the bag to the tightest minimum.
‡Please note: The optional waterproof Dri-LX outer provides an extra seam-sealed outer shell to the bag. While a shelled half bag is not designed to be used alone in heavy rain (water will find its way in) the shell does protect the bag when it is used outdoors without a tent.
Camp down to 10°C and bivvy down to between 5°C and 0°C.*
Half-bags need to be light, and the Wafer Half Bag certainly hits the mark. Add this 165gm item to your pack and you're set up for a lightweight camp at 10°C (as long as you have a warm jacket) or a bivvy down to about 0°C.*
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.
...A half-bag is the lightest answer.
The optional waterproof Dri-LX outer provides an extra seam-sealed outer shell to the bag. While a shelled half bag is not designed to be used alone 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.
We have given two separate TOTs (Typical Operating Temperatures) for this half-bag.
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.
At just 64gsm, Dri-LX is our lightest 2-layer breathable waterproof rip-stop nylon fabric. Its remarkably low weight not only makes for a lighter load, but also reduces pack size. Its excellent waterproofing qualities are in part due to how it can be taped at the seams to create a waterproof shell for sleeping bags and clothing.
10X, PHD's first 10 Denier Fabric. 9,000 metres of the yarn used to weave 10X weighs just 10g, that's about the same as a £1 coin! For all its thinness 10X is amazingly downproof and with reasonable care will go on giving you good service for years.
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.
