I have this belt for several years. I do not use the supplied belt, which saw the kidneys ("sharp" edges), but with the belt of my pants .. Fixation is a rock solid, even with a big SLR and a heavy and imposing target (17-55 F / 2.8). a flat for the length of the support plate, which sometimes bothers to sit, especially by car. I used the EVO hike in forest and mountains, amusement parks, biking output, mushrooms. It's really top: no sloshing, no neck strap. Just remember to put a visor and a protective filter on the objo, because sometimes you type in the branches. I look forward to the release of the B-Grip UNO on amazon, intended for bridges, and will be ideal for my short or pancake lenses (so light). It is much shorter than the EVO.
