Lighten Your Load with This Bag
Spoiler alert: I'm running about 9 miles every day to work now (4.5 there and 4.5 back).
Because of this run commute to work, I needed a bag that was going to hold a change of clothes, my laptop, planner and toiletry supplies without being too big or flopping around too much.
I also needed something weatherproof, because lord knows I can't work with a soaking wet laptop, and I need warm, dry clothes to change into once I get to work.
Enter Proviz Reflect 360 Dry bag.
This bag holds all of my gear and is waterproof (it's built of the same material as an inner tube!).
