What Our Gearhead(R) Experts Are Saying:"I've used this bag as my everyday commuter for months and switched it to backpack mode the second I hit the trailhead on a Friday afternoon road trip. The padded laptop compartment kept my gear safe through a sudden downpour thanks to the weatherproof ripstop exterior."Weekday mornings and weekend getaways rarely call for the same bag, but the Global Pro 3-Way Briefcase from Topo Designs handles both without hesitation. Carried by hand into a downtown office or slung on as a backpack for a trailhead parking lot, it moves with us through whatever the day actually looks like, no swap required. The dual ripstop exterior with interior TAF coating shrugs off rain on the walk from car to door, while stowable backpack straps and a removable shoulder strap let it shift carry styles in seconds. A padded laptop compartment and dedicated water bottle sleeve keep the essentials organized whether we're headed to a meeting or a mountain town.
