Exploration Systems, or “E.S.”, are designed for world class adventures. The bags are fully featured, organizable, and lightweight. Common features sets throughout the E.S. line include the E.S. Two Wheel system. All of the wheels are housed by a protective covering to protect them from any damage, and the wheels themselves are oversized to get over a variety of obstacles, be it urban or off-road. Bags in the E.S. collect also use the Touch Point Handle system which makes for an easily retractable and extending handle which locks into place and utilizes a soft molded grip that is very comfortable on the hand. They will lock in place when they are extended and they will also lock in place when they are put back into the bag. All of the bags in the Exploration series come with what is known as the “No Matter What” Guarantee. That means that no matter what your bag goes through, be it damaged by the airline carrier itself, or protected form and defects in work or craftsmanship, we will fix it or replace it for free no matter what.
