"What Our Gearhead® Experts Are Saying:""I use the Aenergy TR 5L Pack for everything from tempo trail runs to long hill repeats. It’s lightweight, breathes well, and the fit system keeps it super secure without rubbing. The flask pockets are super handy, and the back storage easily holds a light shell or some snacks.""Whether we’re chasing a sunrise summit or logging miles on a dusty singletrack, the Aenergy TR 5L Pack delivers a snug, barely-there feel with all the right features to keep us fueled and focused. Built with lightweight, breathable polyester and a fit system that dials in across the chest and sides, this vest-style pack minimizes bounce and maximizes comfort—even when we're moving fast. Despite its minimalist profile, it carries more than enough for our long runs or race efforts. With soft flask holders (yes, flasks included), a hydration system-compatible sleeve, a secure zippered back pocket, and quick-access front drop-in pockets, it keeps nutrition and layers exactly where we need them. It even includes a pole carry option for mixed terrain or longer adventures. All function, no fuss."
