Grubbs from Billings Montana, crafts a beautiful strap called the Wapiti Strap.
It's made from strong nylon webbing with a shoulder pad made of Montana Elk
The elk leather is very comfortable on your neck for extended periods of time and as David says "like a comfortable pair of gloves, the Wapiti Strap gets better with age".
During an extended assignment in Cambodia, Vietnam, Myanmar and India, I used David's Wapiti strap on my Canon Mark II with a 16-35 f2.8 attached, I found it to be extremely comfortable and of very high quality. In climates, both hot and humid, as well as hot and dry, the Wapiti strap performed flawlessly.
You can see the supple elk leather logo and the area which hugs your shoulder when wearing the Wapiti strap. David makes them available in 32, 36 and 40 inch models as well as custom lengths. Be sure to order the correct attachment type for your camera, either the split ring or the Strap connection type.

If you are looking for a simple, no-nonsense, high quality, comfortable camera strap that will get better the longer you own it, check out Dave Grubbs's Wapiti strap. The Wapiti is one of the nicest, custom made straps around!
David now offers his new adjustable "Bugle strap" which is adjustable from from 32 to 50 inches. Although I have not had a chance to try one, I suspect it is a great option too.
Wapti straps are available on line direct from Wapiti for less than $40.00.
