AttackPAK Fitting

Belt Sizing

Please "measure twice" so we can "cut once."


Our goal is to deliver the correct size the first time. Please order a measured size, rather than use pants size. We will build the inner and outer belts to tighten 1.5-2″ and lengthen 6-7″ from the measurement that you order. This adjustment range is usually enough to accommodate winter weight and a slight drop in weight.


Pants size is unreliable because it will 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.

Tactical Belt Sizing Guide

Our tactical belts are designed for durability and comfort. This table tells you the adjustment range on Small, Medium, Large, and Extra Large belts. It also tells you the length of the belt pad that will be on an Alpha, Delta, or Bravo belt.

Pro tip: Use a string and tape measure, or measure your belt from the end of the buckle to the hole that you use

Formula (in inches)

C7 Vertebra–Iliac Crest+2″= Optimal Frame Size (OFS)


C7 Vertebra to the floor

C7 is the bony part of your spine at the back of your neck, just above your shoulders. Stand straight and drop the tape down your back to the floor.

Iliac Crest to the floor

Place your hands on your hipbones with your thumbs pointing back toward your spine and your fingers wrapping forward. Hold your hands out parallel to the floor and drop the tape from your hands to the floor.

Most of our packs have 4″ of adjustment in harness height, but our lightweight Paladin pack for competition shooters eliminates adjustment to save weight. Order with the confidence that we will communicate to get you custom fitted.

Why AttackPAK

Protected by Two Utility Patents

Built for our sons who go to battle, only available from AttackPAK. The Integrated Load Carriage System (ILCS) design is protected by multiple United States utility patents, giving U.S. soldiers a definitive battlefield advantage. Our solution is simple: harness gravity and friction to solve a decades old military problem. Nobody else has solved this problem so our soldiers have been forced to choose between quick jettison and ergonomic performance. This design gives you both, to bring you home safe.

What Our Valued Customers Say

“I can really tell the difference. The pressure is off your chest. It doesn’t even feel like I have a plate carrier on. No restrictions in breathing. I can easily move. The weight is on my hips, not on my back. Wow what a difference. Awesome!”

Jose (USAF)

“And for the armor panel support - honestly, I am blown away. I couldn’t have imagined it making that much of a difference. I am usually the first to ditch my kit the second I get a break, but this one I wore all day, even driving, and it stayed comfortable. Remarkable!”

Grove

“I have never used a ruck that didn’t make my spine feel compressed before this system.”

Brandon

“I took a hard core fall down a waterfall and busted a few of the plastic buckles.  Having them all modular and interchangeable was a true lifesaver.”

Bryan

Daily Carry, Zero Compromise

“I love the concept of this pack frame system. As a career Marine Infantryman I loved the capability of the modern gun belts, but hated the way it interfered with using the main packs hip straps. I believe you have the first belt that fits what an infantryman actually needs. A belt that integrates well with the pack but allows for mounting gear on the belt.”
