MSS Sleep System Condition Guide
- Premium: Signs of use are virtually absent. The best military surplus you can get. Gear in this condition is very rare and doesn’t last long after we list it.
- Very Good: Military surplus in above average condition. Will have some signs of use which could include surface dirt, abrasions and marker but will be void of holes, rips, tears or any significant defects.
- Good: is just that, this gear will have some character but is 100% functional. Expect slightly deeper abrasions, wear in high stress areas, a small hole or two. Small repairs may be present.
- Fair: Items in this grade need a bit of love, they will have rips, tears and stains. These guys may be missing a snap, the zippers may not function or may have deeper scars than their counter- parts, but they’ll get the job done after some repairs.

Very happy with this sleep system. I was hesitant about purchasing something used knowing it was possible some of the pieces might have some damage. I found that it was mostly cosmetic (slight discoloration). Overall, this sleep system is in great condition.
