What makes these Superlight Shorts so respected on the water? In addition to their obvious good looks, Simms has created COR3™ Technology, an exclusive fabric finish with UPF50+ sun protection that also minimizes odor and provides outstanding wicking and quick-dry performance. Plus, Cool Control™ fabric technology is incorporated to help you keep your cool. Durable, 100% nylon with deep mesh hand pockets, an internal cell phone pocket, a zippered cargo pocket and a zippered back pocket hold essentials like pliers, spare sinkers and your sunscreen. The partial elastic waist includes a fly and button closure.
