Ideal for a day hike or minimalist backpacking trip, the Thule Capstone 50L has a MicroAdjust suspension system that makes the pack fully adjustable for the perfect fit, a tensioned mesh back panel for maximum breathability and a built in rain cover. The MicroAdjust Suspension system lets you adjust the pack's torso length while the pack is on your back to easily dial in the perfect fit. The tensioned mesh back panel provides unparalleled breathability, keeping you cool and dry on the trail. Top, side and bottom access to the main compartment make it easy to get to your gear on the trail as well as load and unload the pack. Zipped pockets in the lid and hip belt store sunglasses and other small items, while the stretch fabric shove-it pocket provides fast access to often used gear. Side compression straps let you cinch down your load or lash gear to the outside of the pack, while hiking pole and ice axe attachments let you stow your hiking tools when not in use. A hydration-compatible design features a reservoir sleeve with drink tube exit port and two side water bottle pockets. The high-visibility, removable rain cover means you can keep your gear dry during storms.
