This backpack is so cool,with many special features! It's brand NEW,with tags still attached. It has multiple zippered pockets on the front,back,on the adjustable strap & inside. On the strap,itself,there is a pocket for glasses & another for any smaller items like change,credit cards,jewelry etc. There is also an adjustable black strap,which can be used for securing to your bike to carry the backpack if you don't want to wear it. On the side,there is a place for your music,as well. I tried to show all the many features in my photos,but they don't really do this amazing backpack justice. It measures a roomy,but compact, 15"×14"(see photos). Perfect for hiking,biking,or other outdoor activities! From a smoke & pet hair free home. Offers are always welcome.
