I purchased and have using the Cotton Carrier to easily carry a Nikon Z6 with a 500mm lens and other size lens mainly for shooting wildlife. Previously I had said a cross body strap was the best purchase I ever made for my camera, but after hauling a heavy camera and lens on long walks and always having to protect it from banging again your side and getting a sore shoulder when setup with a large lens, I was interested in this product. It can take a bit of adjustment to get it and the camera sitting right, but once you are using it, it will spread the load and free up you hands to focus on stabilizing yourself on long walks. Ensure you use the safety strap, it saved my camera a couple times. In a public setting, I felt a bit self conscious wearing it … but after a couple times I got over it and people either see me a serious photographer OR are likely are wondering wear I got his product while they carry a heavy camera kit either in their hands, or worse around their neck.
In retrospect, I likely would have got the version with binoculars holder, but I can add on this accessory later.
Construction has been solid, I have used it on a number of outings now including bringing it along on trips. No complaints.
