Atom Sling Bag 8L

Rode 12 miles with this on and barely noticed it was there. The 8L size swallows my phone, keys, and a light jacket without bulging, and the close fit keeps it from swinging around.

Switched to this from a bulky backpack for my daily bus commute and the close-carrying fit makes it feel like it's barely there. The 8 liters swallow my lunch, a paperback and a water bottle without turning into a lump, and the organization pockets keep my keys from migrating.

Rode 40 minutes to work in the rain and the 8L fit my lunch, a spare tube, and a light jacket with room left over. It stays tight against my back on the bike instead of swinging around, which is exactly what I wanted.
