I'm having an immature chuckle at the poster name and his suggestion for only 1 pair of underwear. I haven't tried just one pair yet. I like having a 2nd pair to wash/dry for smells and/or chafing.
That's a very impressive list. I'm curious to know from others if you trust a base layer and mid-layer under a breathable rain shell to eliminate the need for a puffy vest? Dry winter weather is so much easier to dress for than the humid cold air in the deep south.
Some people like having an extra pair of camp shoes (like crocs) if they have heavy boots. I love my trail runners in Summer to 1st Rifle because they dry out fast and I only carry that one pair. Even your best Gore-tex boots will get wet from sweat or water. Getting them dried out can be such a chore that sometimes just doesn't happen.
I did not see Trekking Poles on the list. This is a major weight redistribution tool that places weight and resulting fatigue away from your ankles and knees to your arms.
Ozark Trail Walmart poles can be had for $20. They are adjustable, very sturdy and plenty light-weight at 20.8 oz; just 3 more ounces than a pair of fancy poles selling for $180.
If you have to choose between extra shoes versus trekking poles, my vote is for poles every time.
You may have blister care supplies in your first aid kit. I had Gorilla tape and moleskin, but now resorting to cheap black duct tape around each pole for foot care and other MacGyver-type repairs on the trail. After watching Randy's recent footcare interview with a Podiatrist, you may also wish to supplement your kit with "cheap black duct tape".
If you're still looking to cut weight, consider using Iodine drops or tablets for water purification instead of a water filter.
