Yet another tweak on the ULA Ohm. Two removable shock cord top straps. Very easy to do, I used two side release cord locks and two glove hooks with some shock cord. The trouble with a single webbing strap is that anything attached is a bit unstable. The shock cord stabilises a tent or stuff sack. They are removable if they are not needed. I’m looking forward to using my modified Ohm. Unfortunately, there won’t be an opportunity until the end of June.
