Lightweight! Just the right size! I use it to carry my reusable shopping bags, as I walk to shops, this wonderful and versitle backpack allows me to have my arms and hands free as I shop! Fits snug to my back and adjustable straps stay on my shoulders while any added weight is distributed for perfect balance & maneuver abilities. The price is worth every penny. I can also keep this bag clean, easily. I also LOVE that I can convert the entire bag into itself and becomes a small pouch (when empty, of course) that I can stash in my purse and I am prepared for my adventurous outings.
