Southern Marsh Dockside Swim Trunk - Anchors . Our first take on coastal wear and we?re pretty sure we nailed it. Whether it?s fishing off the boat, or having a few drinks by the pool, the Dockside Swim Trunk is going to be your favorite pair of shorts for the summer. The outer shell and interior briefs are made of EVAP poplin nylon that dries fast and stays comfortable ? wet or dry. The two grommets in the rear of the trunk allows air to escape when submerged so you never have an inflated swim trunk when getting in the water, while the third grommet on the utility pocket lets water drain so you never have a pocket full of water. Both rear pockets are secured by zippers to make sure nothing important falls out while the two front pockets are angle cut for easy access. The super-soft interior waistband keeps the elastic waistband comfortable to wear all day, even with a belt.
