I just love daypacks, but I like them to be narrow so they won't interfere with arm movement. A sleeker pack just feels better to me. When you are scrambling through brush they don't slow you down.<br><br> Blue Diamond makes a couple of very nice examples for traveling light and fast. I believe my smallest is called the "Bullit pack" and the next larger is called the "Zippo" if memory serves me right. They are favorites of mine.<br><br> I have an Eagle Creek "Guide pack" which may be discontinued now. It is a larger daypack that has an internal frame and fits my long torso. I carrys bigger loads very well. I have to carry water for my dogs, as in the desert I never rely on springs and I question the quality of other sources. This one does it extremely well. A good pack can make a certain weight feel lighter and will carry it more comfortable.<br><br>I suggest trying the packs with weight. Most stores will do this for you. Packs are a very personal item. Good luck.
