Product Description

Adjustable shoulder straps
  • Padded for comfort
  • Secured in place by an adjustable sternum strap, so they never fall off your shoulders
Adjustable LAP-STRAP
  • This unique feature is essential for spinal health. When you sit or squat while wearing the bag, the LAP-STRAP immediately transfers the weight of the bags off the shoulders and spine and onto the thighs without having to remove the shoulder straps. This prevents unhealthy load-bearing through a flexed (rounded) spine.
  • Allows bags to remain accessible at your sides if you choose to remove shoulder straps while seated
Integral hip-loading belt 
  • Takes the weight of the bag off of your spine and shoulders if/when you need to do so for comfort or because of injury
  • IMPORTANT! Use of the hip-loading belt reduces the posture training effect of the BackTpack carrying system
Hip-width adjuster
  • Locking system for desired hip width (2)
Headphone port on each side (8)
Hang loop for storage on a hook
Key fob
