Grundéns Flybridge Shirt, $75, shopgrundens.com; Helly Hansen H2Flow Jacket, $200, hellyhansen.com; Wiley X Nash Blue Sunglasses, $130, wileyx.com
Appropriately named, the Flybridge shirt from Grundéns is water- and stain-resistant, lightweight and breathable, making it ideal for a long summer cruise. On a cool morning, like the one we had when cruising to Sag Harbor, New York, the H2Flow jacket is that rare combination of warm and breathable. Fleecelined pockets are a nice touch for when the weather turns south. Wiley X sunglasses cut down on glare when underway or on the dock.
