The ideal second skin
As I learned with the Aggressor briefs, the perfect base layer is the ideal companion. Makes long days on the bike WAY more comfortable. Their wicking properties in concert with that of an efficient mid layer (if needed) and a Goretex outer make for great comfort and ventilation.
Other than the fit being outstanding, there's little more to say about a product that simply and effectively facilitates comfort.

Jashan S: Second set of the same pants and shirt (Klim Agressor) that i am getting. Great quality. Used it for a 7500km trip and washed and re-used multiple times. Good quality. Would recommend.Feb 6, 2014
Phillip E asked:Is the Aggressor pant designed to be used with the Aggressor brief at the same time or is an either or kind of thing?May 9, 2014
Ronald D:It's an either or thing. The Aggressor pant is simply a long version of the brief. I can tell you they are really comfortable. I wear these under my riding pants and a Klim Aggressor long sleeve top under my jacket. The top looks good enough to remove your jacket without having to then put on a shirt when you stop to eat. These seem to let the right amount of air through as you're riding.May 10, 2014
david b:I have used these with and without briefs ( not the Aggressor brief, the material has been cotton or merino wool ), equally comfortable. When I go on a long ride I wear the seamless merino wool short underpant at the same time rather than a brief since the latter tends to chafe. My reason for wearing both the shorts and pant is mainly for hygiene.May 10, 2014
Richard K:I own both but for me it is either or depending on how cold it is outside- the pant is just a longer version of the shorts. I suppose if you really wanted extra support you could double them up but they are basically a compression shorts like Under Armour. I never wear them at the same time. Hope that helps.... STEEP AND DEEP !!!May 9, 2014
Douglas K:I actually used the aggressor pants against the skin with KLIM tactical shorts over the top, were bit of a thermal barrier for the cooler ride I had today....... riding KTM in Mongolia and use the aggressors to stop some of the chaffing from the knee protectors and were very comfortable on the ride today....May 11, 2014
Rick M asked:Will the Klim Agressor Pants worn under Klim Mojave Pants be all that effective in 85+ degree days to help keep you from ""cooking" ? My concern is that I may be just adding another layer and actually increase the effective heat factor. The same question would be equally valid for the Agressor Shirt worn under a Badlands jacket. Thanks. Appreciate all responses.Jun 22, 2014
Simon N:I ordered this pair of pants to tryout under my BMW Street Guard 3 pants. I live here in Singapore/Malaysia and the temperatures are consistently between 25-34C (77-93F). While this pair of pants is not as warm as many others, I do find the material to be warming. It works OK in the 25C temperatures but is definitely "cooking" on the 34C temperatures. I have much better success in high temperatures with Saloman Trail Running Tights.Jun 22, 2014
