So looking for some input from you guys. I am going on a backpack trip this weekend.

Leaving Sat morning hiking in 10 miles, camping Sat night through Monday morning, and hiking out 10 miles on Monday.
Looking at carrying 1/2 gallon of water. Temps are 49 - 54 at night w/ chance of showers. high is 85 in day times. Hiking along a river/creek so water pumping is available.

My pack is about 25 pounds. Do you guys think that Im packing to much crap or is that pretty fair. Thanks
