The Blade 30 is No Longer Available as of 2015
The Arc'teryx Blade 30 is a svelte overnight business travel backpack. Two logical compartments separate your laptop and documents from clothes and accessories while two external zip pockets provide quick and easy access to business essentials. The bag's best attribute is likely the fact that it meets airline standards for a personal item, which allows you to pack a large carry-on and skip the long lines and extra fees that accompany checked baggage.
The Blade 30 is designed for and excels at overnight business travel. For all things active, it performs quite poorly. Get the Arc'teryx Blade 24 ($175) if you want a more versatile business bag or the Timbuk2 Swig ($80) for the best overall, everyday use backpack.
