a few years ago I bought an "Helix Ground" chair. at about 1lb, I considered it, the absolute max, I'd carry for such an luxury. it has been a mixed bag. ..on one hand it's so very nice to sit in the evening, watching the sun set while soaking in the last of it's warming rays. but there's a down side, I fall asleep and wake up in a good of deal of neck pain.....either my head slumps forward until my chin is resting almost on my chest...or falls back way too far. either direction- there's pain. I just started to address this. It's currently sitting on my office floor while I work out an "extention" off of the chair's frame to support my head ( thinking this should come in at 1-2 oz, using the same hiking poles that I already carry.
