Traveling, whether to work and school or across the globe on your next adventure, will require you to bring along some essential gear. How you choose to transport that laptop, weather-ready clothing, campstove, or repair gear is a matter of preference and intention. 40 liter backpacks intended for high adventure are designed for multi-day trips and a complete storage solution. While urban commuter bags with more compartments intended to organize a wide range of small items are best for riders looking to ride their bike into work.
