I will mention that I added a second connector to my tractor last night, and wore my liner while snowblowing the driveway for an hour last night. In the single digits, this stuff is the bomb! Nice to find another use for it. Even at 5 degrees, I only had the liner up to 3/4. I was so toasty, I didn't bother with the gloves.
Warm is definitely a good thing. I still remember the warm fuzzy feelings of goodness I enjoyed when I first really started using my stuff a few years ago. Had gone to my first Maggie Valley Gathering and when it ended Bill (WFP) and I rode from there to York, PA. It often seems to be cold when we leave MV. It was that year. And it was all the way to York. Cold enough we noticed it all day even properly geared up.
So about a month later I had the jacket liner and gloves. Used them that winter and spring and it was great. Made the trip 250 miles each way to St. Louis one day with temps in the teens just to fart around with the gear.
A year later in MV it really paid off though. Last morning and heading home and it was colder than a Moderator's heart again. Forecasts suggested wouldn't see temps out of the 20s the whole 800 miles home. Ice all over all the bikes that morning. But geared up, plugged in, dialed on the temps and rode quite happily all the way home. Would've been a miserably long day otherwise. But with the Gerbing stuff was just another great day in the saddle.
