First aid (snake anti-venom, blister cushions like the "compeed" product, vaseline for chafing, diarrhea pills, sunscreen, water purification tablets etc)
Toilet paper
Sun hat / watch cap (wear one and put the other in the pack)
Warm socks (They will warm your hands too in pinch, or they are a welcome change when your feet are wet and cold from the days hike)
Two water containers instead of one
The pack itself could probably be lighter. Many ultralight backpacks will weigh less than that snugpak while offering better ergonomics and more storage space.
