Excellent day bag!
"I'd been looking for a water-resistant bag for work and small day trips, and this ticked all the boxes. Comfortably fits the laptop or iPad in the padded sleeve and has a loop to hook the keys to, for easy access. It's tall, narrow profile means I can fit all the essentials, without it shifting my centre of gravity too much. Only downside, is there is no small pocket for quick access to smaller items, but that's what I use the waterbottle pocket for."
