Setup: Adjusting Your Backpack

Proper adjustment of your Blitz 35 Backpack is crucial for comfort and efficient weight distribution. Follow these steps to find your correct size and adjust the harness system.

1. Determine Your Size

To ensure the best fit, measure your waist circumference and torso length.

  • Waist Circumference: Measure around your waist just above the top of your hip bones (approximately two fingers below the belly button).
  • Torso Length: Use a tailor's tape or string. Have a friend measure between the bony bump at the base of your neck (C7 vertebra) to the spot on your spine directly behind your belly button.

3. Adjusting the Harness and Waist Belt

Once you have determined your size, adjust the shoulder harness and waist belt to comfortably distribute the pack's weight. The shoulder straps should sit firmly on your shoulders without excessive pressure, and the waist belt should rest on your hip bones to transfer most of the load.

Maintenance

Proper care will extend the life of your Mystery Ranch Blitz 35 Backpack.

  • Cleaning: Spot clean with mild soap and water. Use a soft brush or cloth to gently scrub soiled areas.
  • Drying: Air dry the backpack completely in a well-ventilated area, away from direct sunlight or heat sources.
  • Avoid Machine Washing: Do not machine wash or tumble dry, as this can damage the fabric, coatings, and structural components of the backpack.
  • Storage: Store your backpack in a cool, dry place when not in use.

Troubleshooting

Here are some common issues and solutions for your backpack:

  • Uncomfortable Fit: Re-evaluate your torso length and waist circumference measurements. Adjust the shoulder harness and waist belt according to the 'Setup' section to ensure proper weight distribution.
  • Zippers Sticking: Apply a small amount of zipper lubricant or graphite from a pencil to the zipper teeth. Gently work the zipper back and forth.
  • Wet Interior: Ensure all zippers are fully closed and flap covers are secured during rain. While the backpack has weather-resistant details, heavy downpours may require a rain cover for complete protection.
  • Load Shifting: Utilize the internal webbing and external compression straps to cinch down your load. Pack heavier items closer to your back and centered.
