I must admit, I was skeptical at first. Trucker cap for running Errr... But after seeing Lesley tested it out in her races and also frustration at my other name brand caps that imho, didn't quite do the job for me, I decided to give this a try. I have since tried the cap on a few runs and happy to report that it's light (hardly notices it while running), absorbs sweat well and doesn't make my head looks like some weird egg shape. In fact, it looks so good that I'm wearing it anywhere and at every possible chance! I even bought one for my running buddy because it's easy to spot a Purpose cap in the crowd!
My Purpose gear
I've used 2 Trucker caps from Purpose and have ordered a third in that amazing pink and blue. So far it has got me through my training long runs and even a marathon. The mesh material works away sweat much better than the big name brand caps that I have. Such that at the end of the run, the cap is still light and nitnhevay soaked with sweat. Plus I can turn it around and the brim is long enough to protect my neck frm the sun. Lastly it also makes a great casual cap too!
