Much better than expected Pros: good fit, 75+ speeds on the freeway don't push the sleeves down from the wrist, comfortable, I look better than I should donning it. Cons: Too hot for 80+ temps at slow speeds, too cold by itself riding below 60 degrees, The cons are overstated. Those conditions are not what this shirt is made for. I use it as a morning base layer under my jacket. I really like this shirt, I'm glad I got 3 of them on closeout. I have a 44" chest and the XL fits like a fitted Nike Pro combat shirt. I could blathering on in greater detail but in reviewing what I wrote I think it succinctly states how i feel October 23, 2015
Good base Have not used this enough to make a solid review but first impressions from 50 degrees up are great. Looking for something that works well from 35-55 degrees and think this might be the ticket. It is certainly a well made product that fits well and is sized correctly. Very happy to date....

The fit and feel is great This shirt is awesome,much more superior than tranditional thermal underwear, love the fit and feel,its great ! I also purchased the pants, I liked the combo so much my wife wanted me to order her a set, and being the good husband that I'am I did exactly what she ask of me,and when she got her set hugs and kisses for me,and warm comfort for her!! Oh buy the way she also loves her combo. Thanks Revzilla's ,for making a old couple warm again :-) :-) April 5, 2015
Size runs big, but has Klim quality I bought a Medium size (my normal size) but it was a bit loose. It would be OK as a regular undershirt but I prefer baselayers to be snug. I gave it to my son (he's happy!) and ordered a Small for myself. This fits much more snugly and is an ideal baselayer. The quality is typical Klim. The price is OK - it's not inexpensive but it's worth it! March 30, 2015
Excellent price and Quality At nearly half the price of other brands of technical undies, I'm definitely buying more. Waiting for spring to see how they breathe in warmer weather. March 22, 2015
This shirt was a life saver....... I purchased this base layer for my trip to morocco with charley Boorman. I originally just needed it in case we hit colder weather in Africa. Well that was an understatement. Morocco had the worst snowfall in 40 years at the base of the Atlas Mountains. Needless to say I was happy to have this shirt. It kept me dry and warm under my klim overland jacket and was relieved I packed it. March 9, 2015
Typical Klim quality As with all Klim products that I've owned to date, this shirt does as advertised and is another winner. October 27, 2014
KLIM Agressor Shirt I was preparing to ride to the Ohio Spyder Rally and temperatures were predicted to be cool, 40's and 50's. I ordered the Klim Aggressor Shirt to wear under my riding gear as an extra layer. It proved to be all I hoped for. Very comfortable, fit was spot on, and it helped keep me warm, but still wicked away moisture and kept me dry, too. I rode over 1300 miles in five days, in cool, windy weather and stayed comfortable the whole time. October 20, 2014
