I fell for the hot tent meme. I don't quite regret it, but I would have been just as warm and way lighter and more comfortable using my hammock setup. Otherwise, I think I packed all the right gear. I've been dialed in for years though - I average 50 days/year backpacking for the past decade. Also, if I recall correctly the temperature range was from like 15 - 70 degrees, so for the first time ever it was beneficial to pack extra clothes. My favorite new gear for that trip was the First Lite 308 lined pant though according to my notes. I do love those thingsI'd be interested to hear what you packed that you wish you didn't? Or what you wish you packed but hadn't?
