Designed for weekend backpacking trips, this ultralight pack provides an impressive level of carrying comfort for a pack this light—it's just over 2 pounds.

Features

  • Activflex LT perimeter frame combines tubular aluminum with flexible Delrin® side rods to allow torso rotation, yet efficiently transfer the load to the hipbelt
  • Freeflow LT back conforms to your back and has ventilation channels and a central breezeway to keep you cool
  • Streamlined shape fits close to the body for stability; over-the-top compression strap snugs loads close
  • Stretch front stash pocket accommodates bulky gear; mesh side pockets are perfect for water bottles
  • Tip grips are paired with speed hooks to securely hold trekking poles; pack also has multiple lash loops
  • Hydration-compatible design accepts most popular types of reservoirs (sold separately); you can route the sip tube over either shoulder
  • Stretch-mesh shoulder-strap pocket fits a camera
  • The REI Flash 45 Pack also includes handy hipbelt pockets where you can stash small trail essentials
  • REI is Climate Neutral Certified; as we work to actively reduce our footprint, we measure annual carbon emissions and purchase an equivalent amount of verified carbon credits
