Upgrade your Mystery Ranch or Alice pack with a new AttackPAK Spine™. This version has a zig zag to better contour over body armor plates. The frame is curved to fit snugly over your plates, moving pack weight closer to your center of gravity, eliminating the need for bolsters parasitic weight. This spine is also a good choice if you will wear your pack without body armor.
The upgrade version of our Spines™ is wider at the top to fit these legacy packs. All AttackPAK designs shave weight where possible. The AttackPAK Standard version is narrower to reduce weight, and will fit very loosely in a Mystery Ranch or Alice pack.

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.
