Who makes the shooting mat with the piece of nylon strap sewn across it. The nylon strap is only sewn on one side and it allows your bipod feet to catch against the strap and helps you preload your bipod legs. I saw it somewhere and can't remember where and now can't find it again. I'd hate to buy another brand and then not have a way to preload my bipod and have the legs slide across the mat.
My Midway mat has the bipod loops your talking about happy with it
