Omg! I have purchased so many backpacks and always disappointed in some way. On a 10 day vacation with many tours, I used this backpack. It’s so lightweight with comfortable straps so you can put things in it and it doesn’t hurt your back, neck or shoulders. I am a plus size woman, 65+ years and even though we were in 80 degree weather in Mexico, I was to able to wear this without any distress. With that being said, my sister kept using different backpacks to find the right one that was practical and comfortable and she said she wished she had one like mine. So when I got home, I bought one for her. She was so happy! Mine is the neon color so I got her the more subdued blue one. I bought definitely buy again if this one gets worn out.
