I can't help but feel like you are bringing too much clothing for only four days.
- Marmot Insulated Jacket
- REI Fleece jacket
- Nike Mid-weight
Is there a need for all of these middle layers? Personally I would take the mid-weight and either the fleece or the jacket, but not both.
-TNF Hiking pants
-TNF Convertibles
-Running shorts
Far too many lower body items for only four days. Personally I would nix two of those, but since you probably won't want to skinny dip, I would just nix hiking pants and sleep in my boxers-- or some combination, but three pairs of pants is overkill.
-EMS lightweight T
-TNF T
What is the reason for two lightweight t-shirts? I would just take one lightweight T and the mid-wt top as mentioned above.
-Nix the spare batteries-- just put fresh ones in your headlamp before you leave. Unless you are hiking in the dark, fresh batteries should last more than 4 days.
-Forget the packtowel-- just use your bandana or purchase a 2nd bandana-- cheaper and lighter than a packtowel.
