Breaths great Bought this for a new uniform kit. And I was pleasantly surprised how well air flow through the legs. Definitely a good product and would buy again May 10, 2016
All as advertised. No surprises. Good product. Good pants. Work well and keep me as cool as can be expected. I ride on the road to the trail so I could use a pocket for some change or a credit card but other than that it's not a bad pair of pants. June 22, 2015
Great quality I have owned many MX pants in the past. The TLD pants look like quality. The mesh areas offer great venting. These pants do not offer a lot of extras like pockets but for the money they are great October 14, 2013
