So a couple of hours ago I picked up a long sleeve shirt and 3/4 pants from the Under Armour Heat Gear range. They are compression gear but the main idea behind this particular line is to assist in keeping cool. The thoery being that the garment draws moisture away from your skin to keep you feeling dry, while utilising the material to increase the effective evaporative surface area. Sounds logical.......so thought I'd give it a try and Under Armour is cheaper than brands like Skins etc which focus more on the compression side of things. So after an hour long ride with a vented leather jacket and thick bull-it kevlar jeans I can happily say that it was $80 well spent. This shit contains some sort of voodoo magic...seriously. Straight away I felt cool over my chest and down my back......I'm guessing where the bulk of the ventilated air from my jacket goes. My legs cooled off as well, but not as drastically as I don't get that good of airflow through my jeans. They're just too thick. I often think my ventilated leather pants are cooler. When I spread my knees on the highway I could definitely feeling a woosh of cool.....very pleasant. So does UA heat gear make it feel like 20 degrees when it's 30+? No. Does it make it a lot more comfortable to ride in 30+ degree heat? My initial impression is hell yes. I'm thinking those in states with drier heat would probably benefit more also due to it all working on evaporation. Anyway, thought I'd share an experience with something that might help someone here during summer periods. Anyone else out there use this sort of thing to help in Summer?
