Gravel and mountain bike backpack that will give you the edge in races: The Outlander 2L XC is a backpack designed for pro racers who go super light on marathon distances. But honestly, this hydration pack is the perfect choice for any rider looking for a hydration pack that won't limit their speed or style. The front straps are lightweight and made from highly breathable mesh, while the airy back panel ensures you stay dry and cool on fast, strenuous rides. We guarantee you'll love this racer, whether you're a pro or a happy amateur. Style hydrated in action: To keep you hydrated and focused on the road, we've chosen a durable 1.5-litre Elite hydration bladder with a large slide opening at the top for quick ice and water refills. And after the race, the bladder can be completely flipped over for easy cleaning and drying. The Hydraflex drinking tube remains secure and ready to hand with the tube clips.
