I'm out of the 100, my knee is still not good I am hoping to have recovered enough by June to maybe be of help as a pacer but we shall see! I will be back to give SDW100 a go next year though!!!
Nathan womans intensity vest easily the most comfortable if I need to carry more gear I do still opt for the Salomon s-lab 12 pack, it is a fraction too long in the body for me though and I imagine could be a bit hot in the summer but otherwise great!
