AttackPAK Belt Sizing
Please "measure twice" so we can "cut once."
Our goal is to deliver the correct size the first time. We offer exact measurement fitting available exclusively on our website. The actual measurement of your waist will be the most accurate.
Pants sizes vary by manufacturer, and will usually be smaller than your actual waist measurement by 3-4". It is also best to measure over anything that will be worn under the belt, such as an inner belt, regular pants belt, or padding. Belts will usually add .5-1.5"; padding can add 2-3"+ depending on thickness.
If you order the wrong size, we will help you get the correct size and can help accommodate special sizing.
