For your reference, this page contains historical product information.

Not just a hard-core toy, this panel-loading Reactor daypack is built for ultra-marathoners as well as the average athlete on a long trail run.

  • G Fabric is a high-tenacity nylon fabric impregnated with silicone, so its fibers stretch under pressure instead of locking together and tearing
  • Pack has a front zippered pocket, two side mesh pockets and a larger front mesh compression pocket for storing water bottles, jacket and energy food
  • Right at your fingertips, mesh waist zippered pockets on hipbelt for stashing energy bars or gels
  • New, canted bottom prevents sagging and positions pack's load higher on your back for ideal carrying
  • Bottom compression straps and front bungee cord allow you to lash on and carry various technical gear
  • When teammates bonk during races, use the tow loops to literally tow your teammates when in need
  • Wrapping the waist is the laminated, diecut waistbelt with zippered essentials pocket
  • Aero-Tech™ mesh on back panel helps move moisture away to keep you dry
  • Hydration sleeve with an exit port holds a reservoir (sold separately) for hands-free hydration on the trail
  • Reflective tape improves visibility

Imported.

    Great for long and short adventure races. Waist pockets are roomy and perfect for snacks. Outer back pocket is just big enough for shoes. Several straps for adjustability. Fits small/short/women's frames!

    Bottom Line Yes, I would recommend this to a friend

    Comments about Gregory Reactor Pack:

    I love this backpack! I originally bought it for an adventure race but I use it for everthing. It is easily adjustable so you don't strain your back and it is comfortable to run with it on. Its also super light and has many places to store things. I especially love the pockets on the hip strap, which are perfect for storing granola bars in!
    Although the backpack may seem small, you can fit quite a bit of junk in there. I use it not only for my bike commute to work, but also for travelling. I would not recommend using it if you plan to transport a lot of heavy textbooks though, because they won't fit.
    My pocket book cried at the price, but it was worth every penny.

    Bottom Line Yes, I would recommend this to a friend

      Comments about Gregory Reactor Pack:

      I love this pack, I've had it for about 3 years now (mine is black) and I use it for dayhikes and sometimes even for travelling or just sightseeing. There's space for a bladder and I just love the pockets on the hip straps where I put my easily accessible snacks for the day.

      Bottom Line Yes, I would recommend this to a friend
