This has been my edc for the last 4 yrs
Used everyday for the last 4 years and it's never let me down. It's the perfect size for carrying all your edc gear and a jacket but when worn stays tight to the back without protruding. Mine gets absolutely sodden with dirt while Mountain biking so I just put it in a pillow case and wash at 30 . Once dry I spray with nikwax and it's good as new. Done this about 10X now and it's had no effect on the bag. No fading . Tearing or loss or durability. It's just brilliant
