Good strap for a heavy camera.I bought this strap (design B) for my Pentax 67 medium formal SLR.The wide neoprene strap pad really makes carrying a heavier camera more convenient. Surprisingly, the neoprene did not get too hot even hiking in 27C/81F weather.It is lined with rubber dots on the bottom to keep it from sliding. These rubber dots work great if you have a t-shirt on, but if you have a tank top or exposed skin, the rubber dots would get irritating as it would be causing friction against the skin.With a camera the weight of a medium format SLR, you will likely still want a bag if you have the camera with you all day as it is a lot of weight hanging off your neck. In addition, for the Pentax 67 at minimum, likely others, as the strap connects to the top two studs on the camera, the bottom of the camera will press into your body as it is unsupported. This was minor for short periods, but got tedious while hiking.

Easy to install and use. Check diameter of your handlebar first, though.

Fantastic value for the money. I got two, deeply discounted at around $10 each, and am still wondering whether the low price was a mistake. These would be worth it even at regular price. Very sturdy!I attached one to a Pentax K3 with no issues. The other went on my vintage Pentax 35mm, and for that I needed to use a standard hole punch to make the small hole in the little protective leather flaps just a tad wider. On both cameras, the straps hang just right.I am a short woman, and the length is just fine for me with no adjustments. I can either place it over one shoulder, cross-body, or around my neck. The reverse side is a soft suede-like fabric. I especially like how the part right where it hits my shoulder has extra padding.The color is a beautiful cognac brown and looks amazing. (My picture has pretty dark lighting.)I will report back if anything changes, but so far, so good!

Fits my Pentax DSLR. It’s lightweight, and works well.

I need it to fit a 2" diameter opening and it's for 3"

Product works well. The first issue is that it can’t mount to the larger diameter on the frame. I could only mount it to the handlebar. Also it would be nice if it could swivel up and down with phone attached not just the ball that turns the phone around. If you have a pop out button mounted on the back of your phone that gets in the way. Maybe you should have 2 slides for top and bottom.

Folded diameter is about 8 inches which makes it possible to take on most outings.

This has made carrying my heavy pentax 6x7 possible.
