Put your laptop in its padded sleeve and throw the Patagonia Half-Mass Bag over your shoulder. This messenger bag is just the right size to get you through an entire day of work and play. Patagonia designed this bag with 100 recycled polyester and 24 liters of space for your computer, books, and work clothes. A zippered side pocket keeps your keys and phone handy. A padded shoulder strap and small webbing waist belt hold the Half Mass close when youre dodging cars on your bike, and a large reflective strip makes you visible to all those suckers in their SUVs.
