Review on RUPUMPACK 18L Insulated Hydration Backpack with 2.5L BPA Free Bladder - Lightweight Water Daypack for Hiking, Running, Cycling, Camping - Commuter Fit for Men, Women, Kids by Instructor Niederhaus

I have tried 10 day packages from $30-$150 for the Mt Kilimanjaro hike. Ultimately I decided on this one. I'm a female, 5'4" and 110 pounds. This is the only bag with a hip belt that can rest on my thigh bones. The shoulder pads aren't very thick, I agree, as the thicker padded ones tend to being sore on my neck and I don't want a blister on my neck.There isn't much room between the bag and my back so it feels sweaty at the end of the day.The hydration pack worked great and I have 2 every day on Kili Drank liters of water from it. The water drained easily and the mouthpiece cover protected it from all the dust on the mountain. It didn't leak out at the O-ring or the mouthpiece. To keep the tube from freezing on the day of the climb, I used thick long ones wrapped in Christmas stockings.
