For sale is an internal frame backpack by The North Face.  Phantom 50 Model.  Size:L/XL.  Part of the Summit Series.  2017 Expedition Antarctica Edition.  Yellow and Black Color scheme. Size: 50L.

This backpack has seen light use.  There are stains and blemishes on the exterior.  No weird smells.  Clean interior.  It appears to be complete except for the missing sternum strap (I'm not familiar with internal frame packs from The North Face but I've used similar packs from Osprey).  All of the zippers and buckles work.

Issues:

One half of the sternum or chest strap is missing.

There are some dark marks on the yellow areas from use.

The black areas have some worn spots (they appear like white threads in the pictures).

The black areas have a few light spots.

The most worn spot on the pack is at the bottom near where the belt connects to the frame (see the pictures).
