A Friday night free concert in the park with your friends is exactly how you want to spend your evening, and you'll be the hero of the night if you show up with Timbuk2's Sunset Bicycle Rack Trunk. Of course, the bag is impressive, but it's what inside that will really bring out the high fives: a pack of frosty beers ready for enjoyment. San Francisco based Timbuk2's designers have clearly experienced their fair share of summer evenings at the park done right, evidenced by their decision to make the bag to specifically fit a 12 pack of bottles or cans. An included shoulder strap easily turns the bag from pannier to messenger bag once you rack your bike, while a thoughtfully integrated a TPU lining ensures the occasional spills or sweaty can doesn't soak through the washed cotton canvas on the outside of the bag. And as a finishing touch, two zippered pockets on the front of the bag give you space to store you wallet, keys, and a bottle opener.
