Klim Aggressor Brief 4.8 5 14 14
Ok for short rides I own a lot of Klim gear and most of it is first rate. However this particular piece of clothing is not typical Klim quality nor do they work very well. Although the shorts appear to be well made they ride up, on me at least. They end up bunched and are really uncomfortable on longer rides. They need to be longer in the legs. In addition the material does not seem to breathe particularly well, consequently they are hot especially in the heat of an early Arizona Summer day. May 4, 2015
All day riding Great fit and they breath really well. Washout and dry overnight. Solid waist band and the crotch area is very accommodating. April 2, 2015
More comfortable than they look When I unpacked these, I thought the seams would be giving me grief after a day of riding, but no. Fit me well and didn't bunch up or stick and no pressure from seams, I think I'll buy some more! March 2, 2015
Comfortable riding garment These briefs are very comfortable and breath well. October 27, 2014
Great product! I've been using these for a few months and have zero complaints the fit & feel is great. No bunching, breathes well. September 12, 2014
Comfy and dry Keeps me dry and are comfortable. No bunching up either. Nice true fit I would recommend this product. September 1, 2014
No comprimise.. pure comfort Klim Agressor is the best short I've ever used. I definitely recommend this product for adventurers. It's elastic, breathable and fits well. August 20, 2014
Great for summer Bought these to use riding in Big Bend Texas in July. These Klim aggressor briefs were very comfortable in 100+ temps in the desert. I wore jeans over them. July 15, 2014

RevZilla Store asked: Why did you choose this?
Ken B: These are fine and all for those days when you get hot and bothered and want to stay cool but if you're used to wearing boxers these will feel odd; and they really like to help your pants slide off if they're not fastened properly. Apr 2, 2015
