The work bag essentials worth carrying daily: power bank, leak-proof bottle and lunch container, a tech pouch and a personal kit pouch, plus how to keep the bag organized.

The best water bottle for commuting has to pass four tests the trail bottle never faced: no leaking sideways in a bag, no sweating on a laptop, a base that fits a cup holder, and a weight we will carry every day. Picks by commute type.
