I am new to the Ultralight Scene(by new I mean void of ANY ultralight gear) and could use some good advice. Due to knee injuries sustained in the Gulf, I NEED to go ultralight on my bid for completion of the AT in 2016. I'm no stranger to packing/camping but new to long distance. I hope to come in with a base weight of 10 lbs but am unsure if this is realistic or even safe for that matter, for a green distance hiker....Thoughts?
