The Pro Bracelet is exceptionally comfortable. I wear this under motorcycle jacket/gloves so need something that doesn't impinge on movement of wrist etc. the Pro Bracelet does the job well. Metal bracelets are always uncomfortable for me under the riding kit. Easy to adjust strap to correct length. Placing on/off wrist is simple and losing it is highly unlikely due to design of clasp. 6 lines of text is ideal to append all necessary contact/medical information. Thoroughly recommended.
