Our Verdict

Built with long-distance trail running in mind, the CamelBak Zephyr Pro 11L Vest delivers comfort, thoughtful storage, and smart updates that make a difference over long miles. Weighing around 270g with the trekking pole quiver included, it comes with two 500ml Quick Stow flasks and enough capacity to carry food, fluids, and extras for extended outings.

The front flask pockets include elastic loops to hold bottles higher as they empty, which really improves access mid-run. There’s also a secure phone pocket, well-placed chest pockets, and a roomy rear stretch compartment. The engineered knit mesh back panel uses body-mapped ventilation zones to keep you cooler where it matters most, and the fit feels well-balanced thanks to the four-point compression and dual sternum straps.

One of the standout features is the removable trekking pole quiver, which tucks neatly away when not needed. It’s a clever addition for races or hilly routes where poles come in and out regularly. While the quiver partially limits the rear kangaroo pocket, the overall storage layout is still very usable for fastpacking or mountain ultras.
