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

    • 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
