The Pattern
The Gridlock Jumper is where modern geometry meets cozy comfort. Its clean lines and bold gridwork give a contemporary edge to a classic silhouette, while the reversible fabric makes it feel like two designs in one.
On one side, crisp interlocking lines form a structured mosaic; on the other, the same pattern transforms into airy windows of negative space. Featuring a dolman construction that keeps things simple, this jumper is worked flat in one piece with just two seams for effortless assembly. Bishop sleeves and ribbed bands at the neck, hem, and cuffs add a soft balance to the geometric stitch pattern, creating a sweater that’s as wearable as it is striking.
Whether dressed up or paired with your favorite jeans, it’s the kind of piece you’ll reach for again and again. And if you love the texture and structure of this design, don’t miss the matching Gridlock Gloves for a quick and satisfying companion project!
