If you're searching for storage that doesn't sacrifice stability on long trail rides, grab the CamelBak Mule LR 15L Backpack for a low-profile carry and easy hydration while you ride. This pack is outfitted with CamelBak's 3-Liter CRUX lumbar reservoir, offering a more stable shape and placement on the pack than a traditional reservoir. The reservoir also compresses automatically as it drains, ensuring that you won't have that last bit of water sloshing around an empty bladder as you ride. The reservoir is tucked away in a lower pocket that also houses the integrated rain cover and bike-tool organizer, giving you convenient one-stop access to a host of important items. The "LR" in this pack stands for "Low Rider" which is an accurate title given its low-profile design and low center of gravity. Thanks to the Dual Wing hip belt you've got more of the load placed on your hips, giving you greater stability on winding uphills and easier upper body movement for the whole ride. As the name suggests, the Dual-Wing belt system uses two belts--an inner belt that supports and stabilizes, and an outer belt that both compresses the load and offers a quick and convenient storage space on the back of the pack for layers and gear.
