Here is what I wound up with for a trip on the JMT a few years back with my brother so there was some splitting of weight for the tent and stuff. I don't think it is ultralight but it certainly wasn't overweight. If I had to do it over, two main things would change. Take the Thermarest Pro-lite 4 instead of the Ridgerest 3/4. When you have blisters on the feet a full pad is a lot better! That would have added about a pound. Taken my Osprey Aether 60 instead of the GoLite Speed. Nothing wrong with the Speed, it is just not as comfortable as the Osprey over 30 pounds. That would have added another 2-1/2 pounds but would have distributed the weight better.
We went northbound so stopped at Muir Trail mid way up the trail. Had way too much candy. My brother likes M&M's.
Sorry for the format but took it from my page
