I've been up and down the street on this.
I've tried the battery operated gloves. Three different brands and all three are BS. They warm up a little bit when I don't have my hand in them but cool off when I put them on.??????
The heat by wire gloves. Really good when temps are in the 50s, but below that, the heat drops off pretty quick. 40 degree weather, I might as well not be wearing gloves at all. I currently have a set of Gerbing gloves that plug into a controller with the dial on it.
The heated hand grips are out of the question. Just not going to screw around with the aftermarkets that last a few weeks. Been down that road too.
I would like to find a good set of wired gloves that actually provide warmth down into the 20 degree range.

 

I use the Hotwired Cycle gear gloves and jacket liner. The gloves have 3 temp settings. on high my hand feel like there melting !! I have had them for 3 years and very happy. Cycle Gear had a promo of free controller with liner purchase.

 

Gordon’s heated clothing has good reviews made in USA

 

Used Gerbing 12 volt heated gloves on an Iron Butt 1000 with temps down to 28 degrees and 80 miles an hour never a problem with cold hands. Feet were an another issue.

 

I have only used Mobile Warming Leather gauntlet gloves. Lithium batttety operated. Several of my friends have also taken heed to my advice and bought a pair. Zero complaints from any of us. Them gloves are super toasty even with the heat off! Typical wear then in 30-40 degree temps and usually for a couple hours. Batteries still had plenty of juice

 

I have two sets of Gerbing heated gloves that plug in. I have rode in the high teens with them. The G3 version are a bit warmer than the older Nubucks.

They work better if your fairing blocks the wind from your hands. I run apes so fairing does not block wind. I usually use heated grips in conjunction with the gloves, or like on my 18 some wind deflectors for the bars, keep the air off your hands.

Gerbing battery heated gloves here. Medium heat setting is fine, last about 4 hours as I recall.

Love 'em.

YUP on Gerbings wired..........bars are above the fairing with 12" apes........good so far down to about 15*......heated socks too!

 

I have never had a problem with my Gerbings heated liner and Gloves. But mine are the old version when Gordon made them.

Combined with my Heat Demons Heated grip inserts and Hand Grip Shields, nothing but warmth and protection!!! Even riding in the high teens tempature.

I got the Gerbing Vanguard 12v wired gloves this fall and used them for the first time off/on during a ride in high winds and temps down in the upper 30's. I never turned the dial past 3/4 and was perfectly comfortable. And they are very plush and comfy too.
