The Columbia Circuit Breaker Technical Daypack is the perfect pack for day trips or commuting. With tons of design technology, the water-resistant, lightweight design rides efficiently regardless of the load. Techlite straps, a super strong and lightweight material, are molded around breathable mesh inserts providing great cushioning and breathability. The Backdraft back panel features directional foam conduits that force hot air to escape and cool air to circulate. A laptop sleeve, tricot-lined, protects up to a 17-inch laptop. Lots of organization pockets for your small items and compression straps allow cinching down the overall pack volume so everything rides securely. Omni-Shield advanced repellency sheds water and the Tarmaq base is extremely durable.
