I bought a backpack for my husband. He uses it for work. It's bigger than I thought and so have 2 water bottles 1.5l, Lunch Box, Radio and many more things which one (s) so plenty of space needs. And there even was going even more. The backpack, incl. The zippers, makes a very durable impression which was important to us because my husband is a craftsman and the backpack loads of must endure. : D
