HI Paul, I have have one of those. Its good, very handy for organising your kit. Pretty hard wearing, comfy to wear but bloody heavy when empty! I really dont use mine that much apart from as a car based emergency kit bag coz of the weight issue. I tore my acl last year and since then have been lightening my load. I now use either an osprey pack or a predator 45l. Hope that is some help!
