Two large compartments on either side

Multiple pockets inside and out (12 in total)

• Pen pockets inside each compartment
• Large zippered pocket inside each compartment
• Large open-topped pockets
• Small outside pockets on the right and left

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. Since you should not apply a load to a flexed spine (as when seated), the LAP-STRAP transfers the weight immediately off the shoulders and spine to the thighs without removing shoulder straps
• The bags will remain accessible at our sides if you choose to remove shoulder straps

Padded bottoms and side panels against your body

• For durability and comfort

Hang loop for storage on a hook

What's New About the BackTpack 4?

1. Hip-loading belt is an integral part of the bag, not an optional extra. This belt is for taking the weight of the bag off of your spine and shoulders if/when you need to do so for comfort or because of injury.
2. Locking system for hip width. It allows adjustment for narrower or wider hips, and holds the weight of the bags when leaning forward as in bicycling.
3. Narrower back panel creates a contour of shoulder straps for greater comfort, sizing, and stability on shoulders.
4. Streamlined design with angled zipper outer side-pockets.
5. Replaced velcro with magnets or snaps.
6. Moved water bottle holder to exterior.
7. New colors.
8. Headphone/tube port on each side.
9. Inside loops to secure hydration bladders. Also, zipper pocket size has been increased to 10 inches x 7.5 inches to accommodate iPads and 45 rpm records for you vinyl collectors.
