TEPHRA is an ideal shoulder pack for outdoor activities by adopting lightweight materials, equipping both sides zipper access, and having two ways of carrying. Leveraging ultralight cross string to make the pack stable while moving.

Besides the main compartment, there is also a rear zipper pocket and a big mesh pocket. 

 

Two-side zipper closures allow you to quickly access the main compartment no matter in left or right carrying mode.

 

Adopting 3D spacer mesh padding for the shoulder strap and the hidden back pocket makes ventilation possible.  The back hidden pocket is a good place for storing the shoulder strap or cross string.

 

The wide shoulder strap could be adjusted for left and right. The CELL phone bag and shoulder strap pouches can be attached to the shoulder strap of Tephra.
 

May also add the ultralight cross string to prevent the bag from moving to the front. The cross string could be stored in the hidden back pocket while not in use.

 

The shoulder strap could be adjusted to a suitable length and the rest of the webbing could be clipped in the buckle once or twice to avoid a strappy look.

Leverage "alloy carabiner small" to attach TEPHRA on a backpack with daisy chain design. In this way, TEPHRA could provide extra space for your stuff and be used as a summit pack.
