I put our packs together last year & our pillows just didn't do to good a job. They took up a good amount of weight & space in my pack & the bottom line was, they weren't very comfy. I ended up balling up my hiking cloths & pack to sleep on. Could have done that WITHOUT bringing & buying the "hiking" pillow in the first place. Was my biggest mistake in purchasing a pretty important piece of equipment last year, maybe my only mistake.
So, I'm getting new ones, now! Any recommendations will be looked at seriously. I need to sleep good & a good light pillow is a must. Air? I don't know. I'm all ears!
