Hopper Frame Bag

$90.00 - $120.00

Our first true universal fitting frame bag, the Hopper fits most adult sized bikes and many full suspension frame bikes with a vertically mounted shock.

This mid-frame fitting zipperless bag was painstakingly developed to work well whether the bag is empty or full to the brim. With a short length that would make zipper access difficult, we used design knowledge from the popular Mag-Tank cockpit bag combined with a decade of tried and true frame bag manufacturing. The result is a single-handed accessible, panel opening frame bag with an effortless magnetic closure.

We’re now offering the Hopper bag with a hydration bundle! The hydration system includes a 1.5 liter water reservoir, HydraPak Plug n’ Play hose for easy refilling, and our Barnacle handlebar clips. The Hopper does not have a dedicated hydration tube port, but running a hose out behind the flap opening works great!

  • Single handed access with effortless magnetic closure
  • X-Pac panels that are two times as abrasion resistant as standard VX material
  • Single main compartment with adjustable magnetic closure
  • The flap and opening are meticulously designed to work well whether the bag is empty or full to the max
  • Internal structure sewn in top panel allows for versatile use in conjunction with cockpit bags
  • Daisy chain along top tube with adjustable attachment points
  • Made in the USA with domestic and imported materials

The Hopper's unique design allows for the shape to be compressed or expanded over the profile of the bag to fit a wide array of bikes. To best determine fit you may use the sizing charts below.
