“They are of course optically brilliant, and I like the body shape, but I doubt they are durable. The strap pins were securely fitted but have twice worked loose, once on a boardwalk. I managed to catch them before they dropped. Also the rain guard is so tight as to be unusable, especially in the field. So I couldn't recommend them. I know others have experienced the same issues. They were a significant investment for me so the issues are disappointing. I'm envious of our club members who have the old style strap fixings.”
