BackTpack 4 New Features

Multiple pockets inside and out (12 in total)
  • Exterior cell phone pocket with magnetic closure.
  • Pen pockets inside each compartment
  • Large zippered pocket inside each compartment, good size for iPad (9)
  • Large open-topped pockets against body (1)
  • Small outside zippered pockets on the right and left (4)
  • One bottle holder on outside (6)
  • Magnet and snap closures
  • Inside loops for securing hydration packs (9)
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 ergonomic side-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 the ergonomic side-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, long distance carrying, or for some types of spinal pathology.
  • IMPORTANT! Taking all the weight onto the hips reduces the posture training effect of the BackTpack carrying system. For postural-training benefit some weight needs to be applied through the shoulders and spine. This was the design purpose of the ergonomic side-bag 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

    This product is amazing! I have been looking for something like this since I became a white cane user over four years ago. As a blind/visually impaired person, our hands are already occupied with our guide dog and/or white cane. We have to bend a lot to care for our dogs who are our eyes as well as use our hands to “see” things. A purse or traditional backpacks are such a hazard for your back and at greater risk of theft. They are also a nuisance, sliding off your shoulder when you bend over. To be able to carry all you need at your sides and bend and stretch in active ways while being safe and convenient is priceless. Carrying toys, treats, and water for my dog…while also carrying my wallet, iPad, iPhone, keys, spare hat/shades and water for me…no longer a hassle with BackTpack. I am truly amazed and thrilled with this product.

    “As parents, we wanted to try the BackTpack out for ourselves to see why our child chose the BackTpack over her standard style cartoon back pack and so we loaded it up and went out for a walk. We discovered the posture, comfort and balance she found in wearing it was in fact as fantastic as she said. We could now see using the BackTpack not only for her school but for us too at work, doctor visits, park time with our kids or pets, mall shopping, hiking, camping, events, amusement parks, flea market shopping, farmers markets, vacations, tailgating events, and even for quick bagless grocery shopping!”

      Thank you Sarah. So glad your daughter is feeling much better with BackTpack, and that you have experienced it too. We really appreciate your feedback!

    I have used traditional backpacks my whole life. As a 24 year old, I started to become more aware of the need to protect my body from the negative effects associated with bad posture brought on from backpacks which hurt my shoulders and cause my back to hurt. After much research, I found the BackTpack, and I was amazed by the design. I have stopped using traditional backpacks altogether and have used the BackTpack on a daily basis. The design is incredible and really helps me carry my things in a much more natural fashion. Its such a versatile product, and it is a wonderful product that has really helped my shoulders and my back feel free from pain associated with regular backpacks in the marketplace. If your looking for a truly unique backpack that is actually good for your back and shoulders, this is it!

      Thank you Fernando. That is all wonderful to hear. So glad that you are free of pain!

    As a physical therapist with a specialty in ergonomics, I was quite excited to read about the BackTpack and all of the thought and effort that went in to designing such a ‘body-friendly’ product. It did not disappoint. Extremely well made, highly adjustable and so many compartments I need to come up with a system to remind me where I stored everything (much preferable to digging through one big pocket, though!) I am able to walk from one appointment to the next with the weight of all of my equipment evenly distributed across my back and shoulders with my hands free. My physical and occupational therapist co-workers were also quite impressed and immediately began thinking of their patients (and their own children) who could benefit from the BackTpack.

      Wonderful news. Thank you Pam.

    I have had a BackTpack 4 for over three years. I bought it after I found a traditional backpack, which I had migrated to due to shoulder pain from an overly heavy purse, awkward. BackTpack allows me to stand erect. I can easily reach my wallet while in a store. I use by BackTpack on a daily basis for travel, work, and pleasure. The compartments are a generous size, allowing me to carry my latest knitting project, a tablet, a book, a folder for my next meeting, and all the contents of a traditional purse. I like that the straps can be “tucked in” and the handle snapped together for a “brief case” look once I arrive at my meeting location. I like this product so much, I just ordered a second one!

      Thank you Pam. So glad you like your BackTpack so much over all these years.

    With my traditional backpack, I was experiencing back pain and headaches caused by neck strain as the heavy loads would pull on my neck and shoulder muscles. As I need to carry a variety of items such as tools, books and electronics for work and study, I was looking for an ergonomic alternative. With the BackTpack 4, I find that the even weight distribution allows me to stand straight and walk a lot faster even with the same loads I used to carry. The ability to carry loads for a longer period without the constant strain on my neck, shoulders and back have taken the hassle out of walking and using public transport. I am really enjoying the use of my BackTpack 4 and look forward to more innovative and ergonomic products from your company!

      Thank you Sharon for sharing this information. We are so glad you are feeling better in your daily life and work!
