ATD1 Durable Waterproof Backpack for Travel & Hiking - Black | Perfect for Outdoor Adventures, School & Daily Commute

Since its first launch in 2018, we did some small changes in materials, construction or branding at each run. Now, at its 5th production run, it has a completely redesigned bottom construction with a less slanted angle and less stitches facing the ground, new laminated and 100% recycled fabrics for shell and liner, angled shoulder straps attachment points to contour even better to human shape and widened distance between them and load lifters, making these even more efficient at managing the load while allowing also shorter torsos to find it comfortable. Plus, this run will feature Roll top stiffeners to help closing the pack, new "ATD" tonal embroidery for an even more subtle branding, Aluminium hardware on compression straps to open them in a breeze, Stretch side pockets to make easy to use them even when the pack is full and luggage pass through on the back for rolling luggage handle compatibility.

What does not change:

• Top quality materials and almost paranoid construction. We have zero report of an ATD1 that ever failed on his user.
  
• All fabrics are laser-cut (this is almost unique in the bags industry) to prevent any risk of fraying.
• Hidden or clean finished stitches protect both skin and thread from friction.
• Stretch parts are double layered to keep them snappy for decades.
• Flexible 23-55 L / 1220,5 - 3356,3 Cubic Inches volume adapts to any need.
• Measurements: 50-70cm x 30cm x 26cm - 19,7-27,5in x 12in x 10,2in.
  
• The shape maximizes internal space while keeping load close to the back.
• Expandable Roll top construction can be closed on sides or top depending on your needs
• U-shaped zipper on back panel allows for top, side and clamshell opening.
• Top, sides and bottom handles.
• less stitches on liner construction to maximize rain resistance.
• Stretch sleeves keep laptops up to 16 inches suspended from the bottom.
  
• Main compartment has no access on front or sides for peace of mind in crowded areas.
• Front compartment has its own volume and effective organization.
