Of your talking about the newest version, yes I have it. Had the previous incarnation as well and used that a couple years.
The new 8-10x fits my SLC and my Els without a problem, enough room that I can tuck my smaller range finder into. They did away with the interior mesh thankfully. The binoculars can with tethered in on both sides. I added small Ti clips to mine for quick detach to a tripod. The flap and zipper is also improved. The zipper is now a one hand deal. The flap as magnets on the top and bottom to quickly hold open or closed. There is zero bounce on the harness and they improved the front buckle attachment, the older version they were tucked into the harness, great in theory not so much in practice. Now they are accessible but still out f the way. Soon as i add a 12-15X swaro to my line up I will most likely add the larger version.
I have one complaint it would be the outside side pockets aren't big enough for a range finder... wind checker power or other small items yes..range finder no go.
All in all it's fantastic. I love how Sitka isn't satisfied with the status quo and aren't afraid to make improvements
