Here are a few great waterproof laptop bag options for you in blue or black: The 15.6 Inch Portable One Shoulder Waterproof Nylon Laptop Bag in black for R1709 is a superb choice. As a single shoulder bag, it allows hands-free carrying which is perfect for when you're on the go. Its waterproof nylon material keeps your laptop safe from wet weather too.

Both have extra pockets for accessories and the trolley strap lets you wheel your bag along like luggage for easy transport. All three bags are waterproof nylon, come in your requested colors, and have space for a 17 inch laptop. I hope these recommendations are helpful in finding your new waterproof laptop bag!
