Summer Sweaters

Duffield Lane's summer sweaters collection is built around one idea: a great sweater shouldn't be seasonal. Made entirely from 100% Heirloom Cotton — a soft, breathable natural fiber sourced to stand the test of time — our summer knits are lightweight enough for warm evenings and layering over a sundress at the beach, yet substantial enough to feel like the wardrobe investment they are. Signature styles like the beloved Flag Sweater, the Puff Sleeve Cardigan, and the Sport Crew come in a range of colors from classic navy and white to warm stripes and nautical prints. Sized XS through XL, these sweaters translate seamlessly from a morning on the water to dinner on the porch. Every Duffield Lane sweater is crafted to keep its shape wash after wash. Explore our full range of styles, including year-round options and custom sweater services.
