20mm Was so excited to get this trap because I really want a high quality Velcro single length but.. it was just too long for me. They now have a short version (5.5 to 6.75). My wrist is 6.75 and just a little too small so a smidge of the Velcro portion isn’t locked down when I tried it on. I “wore” for about 2 minutes. $35 shipped in the USA. No PayPal. https://www.watchesofespionage.com/products/glomar-explorer-hook-and-loop
