Have used a Loc-on spirit since 1985, have 2 of them. Don't know exact weight but they are light compared to most other stands.
Andy if you are really looking for a lightweight travel stand, check out the Tree suit and sneaky sak.
I carried both with me on the Sambar hunt.
Both fit in a redhead hydration pack along with 11 old deer-me rope on steps. I don't believe the pack with 2 liter bladder, both stands, and steps weighed in at more than 12 lbs.
And with those 2 stands you are set for any type of tree! Sure beat lugging around a normal hang on or climber!
And as far as travel goes, this set up is just like a small carry on back pack.
