I just got a standard small. I like the bag a lot but the straps dig into my neck specially when wearing backpack . I ordered a fnf airlite harness to try with the bag. I see the connection point for straps at the top of the bag being a possible failure point as they are not angled and most of the weight goes to one side of the stitching. Time will tell.
I found this harness to be a real disappointment. No structure, one handed operation was not possible. Lid would not completely enclose the top of the harness, the rangefinder pouch was even worse. The small pocket was just a lump of cordura with a zipper. Good for a can of chew and that’s it. Yes I bought the correct size and know how to adjust it. Kifaru products are usually very well done. This thing was a huge miss.
