I met Jordan Templet at a lightweight backpacking workshop at the Pack and Paddle in Lafayette, back in the spring. He was just about to set off on a thru-hike of the 2,168 mile Appalachian Trail, and he recently completed it in August!
He has written an article about the gear he started with on Springer Mt. vs the gear he ended up with in Maine. Check it out HERE and follow his blog for more updates on what he learned on his hike!
