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.
