What Our Gearhead(R) Experts Are Saying:"I keep the Day Bag folded into its own pocket in my car door for whenever I make an unplanned grocery run. It holds way more than it looks like it should, and the water-resistant fabric means I don't worry about a leaky carton of berries."A farmers market haul or a last-minute grocery run calls for something you can stuff in a pocket and forget about until you need it, and the Day Bag from KAVU is built for exactly that. Cinch it down into its own pouch, clip it to a keyring or toss it in a glove box, and pull it out the second your arms are full. The water-resistant fabric and roomy main compartment mean it handles produce, books, or a beach towel without a second thought.
