gloves
they are 100% polyester, if washed they can only be line dried...also the warning label states not to use if you have a pacemaker or defibrillator....and to check with your doc if you have diabetes, circulatory/heart problems.....they may also affect compasses or magnetic sensing equipment....my plan is to put the batteries in my bib pocket and stash the gloves till I really need'em....they stayed on for over four hours last night on low....which is really low heat, they are intended for hunters, seem to be well made, so I'll let you all know after I use'em this weekend....last ride my one finger was so cold I couldn't even feel that it was cold until I stopped and the little chemical warmers don't reach the fingers as these are supposed to do....i was also told that you can plug the batteries into a 12v source, just get a charger with the right size plug...I'll post fieldtest results on sun or mon.
