all Aerostich products have a right hand wrist sleeve pocket. I keep all medical info there, along with contact number.
Ther is a velcro stip adjacent to it, for alternative attachment purposes, I have attached an alert tag (red) to that velcro, to tell emergency to go thru that zipped pocket,(they will see it because they do a limb search immediatly) and follow procedure, and contact Momma (god willing she was not with me if they are checking that...)
Also have programmed cellphone under ICE (In Case of Emergency) with my wife's cell number.
Don't forget that option, many responders look there when tending aid, it's become a customary link.
