Really impressed with warmth
Great product! Warmest base layer I've ever used. Ordered a Heatrub Ultimate top for my wife, she is always cold, and she was warm while wearing the garment! So I ordered one for myself. Just went for a motorcycle ride this morning at 46 degrees Fahrenheit with just the base layer and my Klim Latitude jacket and I was warm. To get the same level of warmth I usually have a Merino wool base layer, heavy shirt and the same jacket. I'm going to be ordering more for my wife and I, and may even get some to give as Christmas gifts! Really impressed with fit, feel and warmth.
