Don't Go Without.
CamelBak designed the Circuit Hydration Vest for minimalist runners who don't want a big pack cramping their stride. Not to mention, the newly updated Circuit is 30% lighter than years' prior and the new reservoir delivers 20% more water per sip.
More specifically, the included 1.5L Crux reservoir features CamelBak's easy-drinking silicone bite valve for fast flow, while the ergonomic handle makes for easy refills and drying. The Crux is also equipped with an easy-to-use on/off lever that helps revent leaks. CamelBak equipped the vest with an air mesh back panel and vest straps for the ventilated breathability you crave on hot runs. There's also a sweat-proof pocket for electronics, stretch overflow storage for energy snacks, and two Quick Stow flask pockets for those extra long runs. Meanwhile, the reflective details provide added visibility in low-light conditions, and the sternum straps ensure a customizable fit and unimpeded mobility as you tackle your objective.

Love this vest and cheaper than REI!
- Familiarity: I've used it several times
So easy to run with my hydration, endurance food, car keys, and any other small needs strapped neatly, tightly to my back! No sloshing around on a belt, or carrying a water bottle. Bonus: Backcountry's customer service was amazing. I had a technical issue with the first one - they shipped me a new one within 2 days and I was back on the trails!
Great for Trail Runs
- Familiarity: I've put it through the wringer
Perfect size and storage for everything from short training runs to ultras. 50oz of water gets you from aid station to aid station without significantly weighing you down. Front pockets fit keys, granola bars, and iPhone 8 without feeling bulky.
Only slight drawback- bladder cap can be a bit tricky to seal the first couple of uses, but easy enough to get the hang of it.
