Earlier I posted a comparison between heated grips and heated gloves and many of you weighed in with some sage tips. Thanks. I was just about to purchase some heated gloves when I stumbled upon the Venture portable battery powered 7.4 volt heated gloves/vests at my local bike shop. I love the convenience of not having to get wired in. And, on my 1975 R90/6 I would probably need to upgrade my alternator to 400-450 watts (especially if I really splurged and got a heat vest). So, is there anyone who has had both the standard 12 volt gloves/vests that run off the bike battery and also the portable 7.4 volt gloves/vest that Venture makes? I live in NC, so I only need heat for a few months each year and I rarely ride more the two hours in cold/cool (30-45 degree) weather. Thanks for any suggestions.
