Does your pillow creep away from you during the night – or do you sometimes lose it altogether in the dark? I know I do. Here is a method of preventing that for a weight penalty of 1-2 grams. Well worth it. i think it is self-explanatory. I have just tied a piece of 1 mm dyneema to the tabs on either side of their excellent Exped pillow (which I strongly recommend), and included a micro cord lock to cinch it up and secure it. The same method will work with other inflatable pillow such as Klymit’s. They are all made with a heat-sealable material so that a hot iron will create a tab on each side (if there isn’t one) to which you can affix a (very small) grommet – available from Spotlight or haberdashery shops generally. You could do the same sort of thing with the Graham Air for an even more ultralight alternative.
PS: Some people use a spare garment (eg a t-shirt) to do this, placing both the end of their mat and the pillow in it.
PPS: The above arrangement will work better with a length of 1/2″ gross grain ribbon and a plastic buckle (which will not come loose like a cord lock)
