The amount of research and development that has gone in to creating durable fabrics for backpacks is almost impossible to account for. R&D departments the world round have toyed around with materials ranging from waxed cotton to Kevlar and Dyneema fabrics. Yet, few, if any have been as willing to push the boundaries as far as Solid Gray with their Aluminum Backpack.
Rather than looking for a material as tough as metal, the Netherlands-based backpack company actually chose to use aluminum to build their pack. Of course, this choice precipitated its own set of unique design challenges. And for the most part, we think they did a good job overcoming them. For instance, the interior of the backpack features a series of straps (like one for your laptop) and small compartments to protect your gear from being scratched and banged-up by the tough interior. As far as everyday comfort goes, the pack is surprisingly accomplished. The backpack is lightweight and easy to carry, and to top it off, the back padding on the bag is made from a closed cell EPDM foam. A solid choice for those looking to stand out from the crowd.
