I bought a Cotton Carrier to lighten the load on my back while transporting heavy lenses during avian photography.
I soon found the item's fatal flaw: There is a thick velcro strap that keeps the barrel in place. Once you move to detach it (no matter how gentle you are) the ripping sound scares away any bird within 50 yards. I had to pay a shoe repair place a good bit of money to fashion a quiet clip release in its' place.
How stupid of Cotton Co. to release a product, used 50% by nature photographers, with a screaming loud safety strap.
That's so true dadgummit. If the company had only bothered to bring in one, single avian photographer and asked them to try their carrier out, their negative response would have been immediate.
