It’s simple really; I sleep on my side and need something to support my neck. Most text books state that you can make a pillow out of your spare clothes but I don’t carry much in the way of spare items. If I was packing a primaloft top or down waistcoat then chances are I’d be wearing it to boost the rating of my sleeping bag.
For a couple of years I used a Ajungilak pillow but this had developed a leak on a seam that, no matter how I tried to repair it, it would always deflate.
The full monty
The Exped AirPillow is it’s natural successor. It tips the scales at 79g, over 50g lighter than the one it replaces, and the tiny stuff sack supplied weighs a measly 5g. It has two valves on the underside, one to inflate (a one way valve) and the other to deflate the pillow. The Ajungilak had one valve with no self sealing mechanism making it a struggle to get the plug in without letting too much air out. Another plus for the AirPillow then.
The pillow is supplied with a repair kit which is a nice touch, especially given my previous experience. The pack size is good too, being about the same size as a mobile phone.
On paper then it ticks the right boxes, all I need to do now is to get out with it and see whether it lives up to it’s promises.
