Timbuk2 Deploy Convertible Pack Pannier Jet Black OsA rugged pannier that wears well as a backpack. Yes, this is happening. A pet project of our cycling enthused design team, the deploy pack pannier doesn't make you choose; it's a great backpack and a great pannier. Super secure hook and loop pannier attachment offers a dead simple on and off, while clever back paneling and air mesh straps make it legitimately comfortable on your back. And its coolest feature the bike tube roll top closure system.
