Ergonomics, Construction, Fit, Tips Hybrid Bak2Pak™ Carrying System (Patented) Hamptons Construction Hauler Construction Hybrid Fit Guide Assembly Tips Hybrid Bak2Pak Carrying System 1. Why is our low-riding backpack better? A low riding backpack has superior ergonomics and weight distribution.  Traditional backpacks ride high causing stress on your lower back. To support the weight  you must lean forward and shrug the shoulders which is not good for your back, shoulder, and neck.  The ergonomic Bak2Pak system rides near your bum and has a lower center of gravity reducing back strain. Pulls shoulders back for good posture.  No more sweaty back as well.   Collections that have the super ergonomic Bak2Pak system: 1. Hybrid Hamptons Laptop Bag 2. Hybrid Hauler Book Bag 2. Convert from backpack to single strap messenger in a few easy steps.  Click image to enlarge.  Hamptons Construction We try our best to use the best materials and cleverness when we design our bags.  Here is just a sampling of some of our thinking.  Exterior Fabrics Produced with ballistic nylon (yes, the same type of material used to make bulletproof vests) with water resistant backing. Interior Fabrics The main liner is made of nylon with vinyl backing.  The lining is water resistant but not waterproof as we would need to glue the seams or use GoreTex to make it completely waterproof.  The interior is orange not only because we think it looks cool but also to help you see what you put inside your bag.  The smaller compartments are produced with nylon with water resistant backing. Laptop Protection We realize the importance of protecting one's investment...that's why we decided to use a high impact plastic on the backside of the bag along with 10mm high density foam on the front, back and bottom of the laptop compartment.  We also created laptop stabilizers for those who want a snug fit for their laptops.  Did you think velour was only good for jumpsuits?  It's also great to protect your laptop from scratches so we lined the laptop compartment with it. Lumbar "Bum" Pads All BBP Hybrid bags have lumbar pads placed where you need it the most.  The pads are designed with foam and mesh with an air flow channel between the left and right pads to keep you cool. Zippers We use high tech water resistant zippers for the laptop compartment and flat seam zippers throughout the rest of the bag.  We also added some handy zipper pulls to make opening and closing that much easier. Buckles, Rings, and Clips We use mostly hardware made of metal or Acetal (aka Delrin as Dupont calls it).  Metal is tough as literally nails while Acetal, also known as Polyacetal, Polyoxymethylene (POM) or Polyformaldehyde is a high performance engineering polymer that was developed to be a synthetic replacement for metal.  In other words, some super tough plastic!  We also picked oversized buckles not only because they look good because they are so darn easy to use. Stitching, Bar Tacking and Seam Tape We top stitch throughout and bar tack over 20 stress points.  We also use the highest quality seam tape to keep the bag together.  All of the fabric joins are covered and never exposed. No Velcro Generally we think it's evil because if you've ever owned a messenger bag, it's damn noisy when you open the main flap, it snags sweaters, and it sticks to your carpet when you drop your bag on the floor.  On top of that, it also tends to be the first thing that wears out and gets jammed with lint.  So we made a stand against the spread of velcro.  We use it very very limitedly for applications that don't get changed often like the snug fit laptop adjuster.  It's just a necessary evil sometimes.  However, we do like velcro on those retro sneakers. Hauler Construction We try our best to use the best materials and cleverness when we design our bags.  Here is just a sampling of some of our thinking.  Exterior Fabrics Produced with durable nylon backed with vinyl to give it extra toughness and water resistance.  Interior Fabrics The main liner is made of nylon with a polyurethance coating to give it water resistance.  The interior is orange not only because we think it looks cool but also to help you see what you put inside your bag.  Laptop Protection The laptop divider is made of 4mm high density foam.   We also used a high impact plastic on the backside of the bag for some extra protection.  We classify this as light protection compared to our heavy protection Hamptons bags.  Lumbar "Bum" Pads All BBP Hybrid bags have lumbar pads placed where you need it the most.  The pads are designed with foam and mesh with an air flow channel between the left and right pads to keep you cool. Zippers We use high quality zipper with flat seams throughout the bag.  Buckles, Rings, and Clips We use mostly hardware made of metal or Acetal (aka Delrin as Dupont calls it).  Metal is tough as literally nails while Acetal, also known as Polyacetal, Polyoxymethylene (POM) or Polyformaldehyde is a high performance engineering polymer that was developed to be a synthetic replacement for metal.  In other words, some super tough plastic!  We also picked oversized buckles not only because they look good because they are so darn easy to use. Stitching, Bar Tacking and Seam Tape We top stitch throughout and bar tack over 12 stress points.  We also use the highest quality seam tape to keep the bag together.  All of the fabric joins are covered and never exposed.

Hybrid Fit Guide Hybrid bags are meant to be positioned lower than your typical backpack.  Generally this means the lumbar "bum" pads should be positioned around the lumbar area or the small of your back.   Or, the bag should be vertically centered around your upper hip area.  Of course some of you may find it more comfortable for it to be a little lower which works too.   The bag will bounce a bit more that low, but the lumbar "bum" pads help minimize it or you can even use the waiststraps.  Keep in mind the center strap can also be adjusted along with the front/sides straps of the backpack. Assembly Tips Some of our bags come packed with the shoulder strap separate inside the main compartment.  If so, we recommend starting in backpack mode.  Here are 2 pictures showing the backpack mode.   Start off by folding the shoulder strap in half to form the V-shape, then attach the center buckle, and then the sides.   Keep in mind you can adjust the center strap as well as use the roll-up velcro tabs to keep excess strap material to a minimum.   There's also a removable waiststrap as well as snugfit adjusters inside the laptop compartment to keep smaller laptops from sliding side to side.   Hamptons Only.  Snugfit adjusters keep smaller laptops from sliding side to side.   Or, you can remove them all together (especially for Mac's). 3. To convert back, of course you can do the reverse, but we like clicking in the center buckle first and then undoing the rest.
