I've been reading on the gear forum and most everyone seems to favor the windshirts, probably due to the low weight and versatility. However, I'm having a hard time separating what they do with what you could do with a rain jacket. I'm doing the JMT August 4th and while I don't have a complete picture as to what my clothing looks like yet, I don't want redundant clothing. As of right now, I plan on bringing (not counting what I'm wearing): an extra wicking long sleeve shirt, extra running shorts, Patagonia Nano Puff, rain jacket, long john (bottoms), extra pair of ankle socks and briefs, beanie and gloves (?). Sorry, I don't have the weights yet but will post shortly!
Any input would be greatly appreciated.
