This is a great pack to use for day or half day excursions away from base camp. It weighs next to nothing and has plenty of room for water, food, camera, and an extra layer. Maybe a little too much room as there is no way to cinch it down for smaller volumes, but that's the price you pay for the weight savings. I do wish that the straps were longer. I'm 6'2" and have trouble getting my arms inside the straps to put the pack on. I also wish there was a strap or loop on the inside for hanging a water bladder. And if you carry a bottle in the outside pocket and bend over, don't be surprised if the bottle ends up on the ground, in the mud, or floating down stream. You've been warned.
