Bottom line: the number one bug out bag mistake is overpacking. Stay under 20–25% of body weight. This tool keeps you honest with a live weight gauge so you can ditch dead weight before mile two.

Frequently Asked Questions

How heavy should a bug-out bag be?

Keep the loaded pack at or under 20–25% of body weight. A 180-lb adult caps around 36–45 lb including water. If you cannot walk an hour without stopping, cut gear — not the water.

What size pack works for 72 hours?

Most people land in 30–55 liters once water and food are in. Under 25L is a get-home bag. Over 65L usually means you will dump gear on the road.

Does this calculator require an account?

No. It runs in the browser, tracks weight live, and links to live Amazon listings with our tag. No signup.

What is the best empty pack to start with?

For most adults I start with a 30–55L pack that empties around 3.5–5.5 lb. The 5.11 RUSH72 2.0 is my primary tactical pick; hiking packs often beat cheap 'tactical' bags on straps.
