Introduction

A frameless pack is just like it sounds. There's no structure to the a, to the suspension that gives it stability when it's filled with weight. The internal frame pack does not collapse until it reaches a load of about forty five pounds. And the frameless back pack collapses when you reach a load of around 25 pounds. As a frameless pack starts approaching 15 to 20 pounds, the perception of user comfort starts to go down dramatically.
