The United By Blue 45L Range Daypack Backpack is a deceptively light pack. It can hold everything you need for your trek and the best part is it opens up from the front so you can get to the stuff at the bottom of your bag with ease. This Navy/Tan backpack has a water repellent finish, can hold up to a 17" laptop and has sternum and hip straps for added comfort. For every product sold, United By Blue will remove one pound of trash from oceans and waterways.
