We spent a considerable amount of time making sure that the Apex Bag could hold up to a variety of climates and activities. Hundreds of miles were covered accross the country to put this bag to the test before we felt comfortable putting it out in the world. From trail running in the mountains of Montana, to hiking through desers and snowboarding, this bag is incredibly versatile. We made sure each piece of the bag was multi-functional for whatever adventrure you choose to take it on.
