I hooked up my vest today.
First thing I was annoyed with and it was my own fault for not looking at the product closer is the 'SAE Coaxial Adapter'. I bought this add on because I thought it would plug into my current SAE plug for my battery tender and I could skip rewiring the bike for the vest.
I got it all wired up and turned it on. The vest heated up. What more could I ask for. It was about 37 degrees out so it was a perfect day to test it.
Before I headed out on the test I had to figure out what to do with all the wires. My second annoyance was the fact that they send a dual control with the vest.
I am going to order a single control for it.
I ended up tossing the control in my tank bag set on 5, the highest setting, and headed out.
37 degrees out and I am sweating within 3 miles. I had to pull over and turn it down. I set it on 3 and it was still a bit too warm but tolerable. I rode about 25 miles and it kept me more than warm the whole time. I think because I am heating my core it also keeps the rest of my body feeling warm. I was only wearing standard street gloves (with heated grips) and hiking boots and neither my feet or hands ever felt cold.
Further testing will be done and I will order up a single control so I can hopefully find a nice mounting spot for it. I don't want to have to pull over every time I want to change the settings.
