Sorry, but I didn't get the name of the electric suit, the company let the guy go, and I've since retired.
The snowmobile suit I used to have was about 20 years ago, before they went high tech. It was just a generic brand, probably from someplace like tractor supply, sears, target. I was able to ride 20 miles, down to about 35F. After that wore out, I wasn't riding to work so often, and got by with leather jacket, pants, and extra layers underneath, just didn't ride when it was below about 45.
Now that work doesn't interfere, I've been riding more, including colder weather. Seeing how comfortable the guy with the electric heated suit was in really cold weather is what has me thinking about going electric this time. Not cheap, but anything that extends riding time is worth a lot!
He was able to change into and out of that suit in no time, that was what I see as an advantage of the one piece.
