The pack and liner are duplicated on your lighterpack chart. Do you mainly hike in hoodie and tights or do you also have shorts? On the Colorado Trail (2018) I found it helped a lot to have a pack with a little higher volume than 40. We took bear cans, and there are a couple of longer water carries when we benefited from being able to carry 6 liters each. But then, we might have been slower than you; most days we made 14-16 miles; if you go a lot faster then maybe less water is needed. The longest carry was 22 miles. Some parts of the CT are pretty well populated, but some can get a little remote especially towards the western end. We had a Spot then; now we carry an inReach. Overall you list seems to cover all the bases pretty well. We traded some comfort for peace of mind and took closed cell pads rather than air pads. No chance of pad failure. We were so tired every night it didn’t seem to matter what we were sleeping on. Have a good time!
You may have been looking at it when I was editing the list. Sorry about that.
I’ll usually hike in shorts and break out the leggings if it’s cold, and throw on the rain pants if I need a little more warmth. Usually hike in a very light sun shirt / sun hoodie.
I did the first half of the Colorado Trail from Denver to Salida a while ago and carried an even smaller pack than I have now, but was going very light at the time; closed-cell pad, tiny tarp, etc. Was averaging around 20-25 miles per day. Never carried a bear can. The Kakwa 40 I currently have is a size large. It has an internal volume of 44L and an additional 15L of external storage.
