Thread Lightly
Knitwear doesn’t just belong in fall and winter. As rising temperatures return, stick to your essentials—polos, tees, and button-ups, in the form of lightweight knits. From work to weekend to extended vacations, these styles will imbue your wardrobe with summer’s signature worry-free attitude.
NOW TRENDING
The Brenan Polo Shirt
Seasons change, but your wardrobe should stay on trend. This polo’s open collar is an instantly distinguishable detail that brings a more polished aesthetic to the forefront. Crafted of our bestselling linen, the soft knit feel makes versatile dressing for warm days and summer nights a breeze.

VACATION READY
The Striped Tee
Stripes and summertime just go together. Besides its timeless appeal, this tee makes for a universally smart staple. Grab this one out of your closet for a casual look with shorts or go warm-weather sporty with a jogger.
