Earlier this afternoon I saw the Gotham sound presentation of the Viviana Straps. Like the URSA straps, they have come in beige and black, they are thin and don't heat up like my current Neo Packs. They also both contain a non allergenic polyurethane for extra grip so the pack stays in place and won't slide off from sweat. For the price of $36 US, it's a done deal for me, I also like that it contains a two additional pouches for the excess wires. Who's used these, and what does everyone think of them? Would you prefer these over the URSA's? If you haven't made a decision yet, please take look at Gotham Sound review video here.
