Abstract: A user borne load carrying system comprising a support structure that is securable to, or otherwise carryable by, a user, and a retention mechanism to secure a load to the support structure. The retention mechanism includes a girth-like embrasure of friction enhancing material adapted to encircle the load. The retention mechanism further includes an adjustment mechanism in the form of a strap mechanism coupled to the support structure and extending across the embrasure. The strap mechanism urges the embrasure and load against each other and the support structure to thereby secure the load to the support structure.
