The Eberlestock J263M is a scalable pack system.  At its heart is a modular 2600 cubic inch internal frame pack that employs our patented Cam Expansion system.  Its unique design allows it to perform exceptionally well in a variety of configurations.  It is reducible all the way down to a drag bag and a fanny pack, and scalable all the way up to a full-scale 7600 cubic inch freighter that can tackle carrying anything from an M4 to the M107 Barrett, with a variety of gear compartments and storage spaces that are designed for flexibility, ease of operation, and accessibility.  It has the rugged, field-proven construction that has been impressing customers around the world since we perfected our pack design and construction concepts.  And above all, it is designed for comfort, in order to ride well day after day, and to increase the agility of those who are lucky enough to have at the heart of their mission-essential gear.

The Skycrane...  ...is an easy to use, full-featured pack unlike anything that has ever come before it.   It's easy and fun to use, and is designed to have such a variety of uses that you will find it capable of doing just about anything, great or small, that you'd want to do with a backpack.  It's comfortable, diverse, rugged, and, well, full of superlatives.

The J263 Skycrane introduces a new concept:  a modular internal frame backpack that has many "firsts" embedded into it.  First application of a Cam Expansion Load Bay backpack.  First strapless case carriage.  First removable Backscabbard convertible to a drag bag.  First use of this type of modular backpack concept.

It certainly is the "first of its kind."  Take a look, and you may agree that this is the world's most interesting backpack.  Not to mention that it's the world's most versatile backpack
