This is a midsized (42 liters) pack made by Elemental Horizons, it’s clamshell design, fabric is a very tough X Pac, the roomy water bottle pockets are a sturdy (320d) ripstop nylon. There is a zipped front pocket that is roughly 7 liters in addition to the main bag.  It comes with a removable frame (5.5 oz) and several accessory pockets- two hip belt pockets, a water bottle pocket and a bear spray pocket- all in the same ripstop nylon as the side pockets.

Also includes a custom setup to lash snowshoes or skis (or something else?)- these are removable (as are all the pockets) if not needed.

The pack without pockets or frame weighs 24.5 oz, with all pockets and frame 35 oz.

A lightweight pack that can handle 25-30 lbs w/o any drama, but extremely robust with X Pac and 320d fabrics.

Very nice pack with no holes, tears or any damage.

I paid $400 with the pockets, selling for $250 w/ all extras.
