I've used this pack for long day hikes and have hauled 20-25lbs with my 10 essentials, extra layers, food and water. It is very comfortable and lightweight. It just feels like there is a pillow strapped to my back. The drawback is that on hot days, there is no ventilation for the back area. I then used my osprey pack for comparison, and while it is ventilated with more support, I definitely felt the weight much more even with the same amount of stuff. I still prefer the GoLite Jam2 for day hikes. Be sure to be very organized with your stuff as there are only 2 compartments, a hydration bladder pocket and no extra organizers within the pack (which I prefer, to minimize weight and unnecessary extras).
