The Basham Race Vest is engineered from the specifications of professional Ultrarunner (and Oregon native) Amanda Basham. The Basham’s defining characteristic is its incredibly small footprint which reduces weight and increases heat dissipation. Despite its size, it can carry up to 2 bottles as well as other accessories.

This pack includes an UltraFlask 550 Hybrid Bottle that can fit horizontally in the insulated compartment and has room for an alternative bottle in the upper quick stash pocket. The quick stash pocket is built from 4-way stretch mesh for maximum capacity and features a magnetic closure to keep contents secure yet accessible. An additional quick stash pocket sits on top of the insulated bottle compartment. This additional outer pocket remains functional even when the inner pocket is full.

This pack is constructed of new UltrAcool Light Mesh. The shoulder straps are narrow, have on-the-go access pockets, and can carry a large cell phone. Adjustment straps provide a perfect fit. One size fits most.

  • Safety stitched bar tack on all stress points.
  • Zipper pulls are quiet, bounce free, and both easy to see and use.
