Sonoma County outdoor products company CamelBak, known worldwide for its innovative hydration products, has just released an ultra-light, minimalistic vest geared to medium- and long-distance runners.

Weighing in at a mere 6 ounces, the Ultra Pro Vest is the first hydration pack in the company’s lineup that doesn’t use a reservoir — a boon to those who dislike large-bladder sloshiness and sucking on straws. Instead, each of the two front pockets holds an easy-to-access 17-ounce quick-stow bottles (1L total); the bottles are collapsible, lightweight, possess one-piece silicone bite valves, and can be removed for cleaning.

A zippered front pocket fits most smartphones, while small open front pockets hold keys or salt tabs.

Rear storage pockets hold layers, a rain shell, fuel bars and/or an additional reservoir for longer runs. Other features include dual adjustable sternum straps, a breathable cushioned mesh to maximize airflow and keep you cooler, reflectivity on front and back, and a built-in safety whistle. Comes in three unisex sizes (S, M, L). $120. camelbak.com.
