That is my 3-season gear base weight. The kit includes a Marmot 20 degree bag and a BA Fly Creek tent. With a bear can added, this is the gear I used on my last JMT through hike. It rained a lot on that trip and temps got to the mid 20’s on a couple of nights. I stayed warm and dry. My basic gear list is posted on my blog, Theoldbackpacker.com if you are interested. I would probably add a few stay-dry items if I were to use the gear strictly in western Washington though.
