This thermal is soft, comfortable warm. I was impressed with how much heat HU can generate/retain. I can't recall ever really getting sweaty which I find a massive plus as it means the under layer is breathable and helps me regulate my temperature. Great product, I'll definitely buy again.
I am a letter carrier for Canada Post. Heat Ultra topsa and bottoms are a perfect fit. Very comfortable and breath very well. They keep me warm during the winter. Since i walk a lot, i usualy tend to sweat with all my layers, but with heat ultra I sweat less than usual which for me is a major plus.
