Reigning Champ Coach's Pant / $170
Finding a pair of office appropriate pants that also look just as at home on the course or field is rather tough. Reigning Champ fixed that with their Coach's Pant. Made from proprietary Primeflex fabric that has four-way stretch, the Coach's Pant resists wrinkles, is anti-microbial (they won't stink), and repels water, so you can play a few more holes even if there's a bit of rain. While the waistband looks like that of your normal casual pant and has loops for a belt, it has a hidden elastic band on the inside, making the pants feel more like joggers than office attire. Each pocket, including the concealed one on the back, is zipper protected so nothing falls out during your back swing.
Sizing: Tailored and trim, but not skinny. Take your most common size, sizing down only if in serious doubt.
