Just forget about using your jacket for a pillow. Wake up with a stiff neck, and can't get comfy? All this will become a thing of the past--even for the ultralight traveler. The AXL Air Pillow is light, at a scant 1.6oz, with huge benefits, including packing down to the size of an energy bar. The offset I-beam construction provides consistent stability, the four-way stretch nylon is smooth next to skin, and the micro-adjust valve allows you to control how firm or soft your dreamy pillow should be.
