I think they’re only 4 or 5 lbs.
Even that could be hefty, if you’d done the foolish thing and walk the Appalachian trail.
That’s a huge extra weight on a long multi day trek.
It’s be interesting to see someone do the entire Appalachian Trail with these. Wonder how he’ll fare vs ultralight hikers. The current record is 22 days for 2200 miles.
This is a fully supported trek with a ground team providing food, rest and gear.
