When we're hiking out to camp from Friday to Sunday, we stuff full our Bridger 55L Backpack. Its capacity is the perfect amount for those two-day treks where we can fine-tune our load. The Bridger features an Endurance Yoke back with an internal spring-steel wireframe for ergonomic fitting to our back. This centers its weight properly on us so we won't be hunched over in pain at the end of each day. We like that it has dual top and front access so we can grab what we need without the hassle of scouring from the top down.
