FAQ

When are you getting more stock in?

Military surplus comes in bulk lots — we can’t choose sizes.

Smaller sizes are more common; larger ones are rare and sell out fast.

Restocks depend on military releases, so they can take time.

Use the stock alert button on the product page to get emailed when your size returns.

How are items graded

We sell both new and used military goods.

New items

All new stock is sourced from suppliers worldwide and arrives factory-new, usually in original packaging.

Used items

Used kit comes directly from military surplus and is graded as follows:

  • Super Grade — Unissued or unused condition. The item is like new, but may not include its original packaging.
  • Grade 1 — Previously issued and lightly used. Fully functional and ready for immediate use.
  • Grade 2 — Heavier signs of use. Still serviceable, but may have visible defects such as small rips, stains, or minor damage to zips or fastenings.
