Imagine my suprise and delight, when I tried on my big Friesian mare, the new Beta Bi Harness I ordered through our own Jerry Trapani from Yanni's Harness shop, to find that the "empathy" breast collar has a big steel loop on each side that the buckle strap for the trace attaches to. Yippee!!! Very easy to configure tandem bars to attach to it!! The harness is easily convertible single, pair, tandem, and other multiples! BTW - Jerry - it all fits just fine! So, if you are in the market for a multipurpose, easy care harness that is great for marathon and nice enough for presentation - you might want to contact Jerry.
