Review on Under Armour Men's HeatGear Armour 2.0 3/4 Leggings: Next-level Performance for Men by Brian Rogers

They are great. Warm - but not hot. Fitted, not tight. Lungs - you hardly notice they're there. The sweat evaporates, but I don't feel the cooling effect. They are very comfortable, including around the waist - I'm not a six pack guy so a comfortable waist belt is important. They do not crawl or jam. They stretch well in all of my exercises, including stretching. I am very happy with my purchase. I've seen reviews of similar leggings products criticizing that leggings don't help when riding a motorcycle. I own/drive a motorcycle. These are athletic leggings. They are not windproof and not as thick as Thermik. The heat they give comes from physical activity. Most athletic leggings, even winter leggings, are designed to keep a comfortable layer of warmth during exercise. Functional underwear with windproof inserts was created for bikers. In my experience, I wear best under a leather or textile top layer (chaps, trousers) and thermal underwear (I wear lined trousers).
