3-Day Bag Buying Guide

3-Day Bag Buying Guide

What to actually buy when building your go-bag — curated gear recommendations across every category, from the pack itself to fire, water, shelter, and more.

Building a 3-Day Bag doesn't require the most expensive gear on the market. It requires the right gear — reliable, lightweight, and appropriate for your environment. These are the products our instructors recommend and that students use to complete their Basic Preparedness coursework.

The Pack

Your bag needs to carry 15-20% of your body weight comfortably over distance. Look for a 50-60L pack with a structured hip belt, load-transfer frame, and MOLLE webbing. A built-in rain cover is a bonus.
