Condition Guide

Surplus is real military gear, and the exact conditions may vary.  We grade used military surplus to give you options and offer a clearer description. Military gear was built well and used by soldiers proving its tested quality.  We hope you find that it serves you well. 

Grade 1 Like New:  Out of the factory case or may have only minor signs of use or storage marks.

Grade 2 Used: What we call normal used surplus. The gear is fully usable and shows normal signs of use with a lot of life left. Some items may have stains, writing, color fading, repairs, and or surface rust on them.  We find that up to a small 1/4” hole or frays does not repair well and do not affect the gears performance.
