Meet the Harper Tee — Our Go-To Boxy Slub Essential
At NSF, we believe basics should be anything but basic — and the Harper Tee is proof. This year-round core essential has become a customer favorite for its easy fit, lived-in feel, and perfectly relaxed silhouette.
The Balance Between Structure and Ease
The Harper Tee is designed with a boxy, slightly oversized fit that makes it incredibly easy to wear — whether layered or on its own. The short sleeves hit at just the right spot, and the clean hems and neckline give it a polished, modern finish while still staying true to NSF’s laid-back vibe.
With its classic crewneck and effortless shape, the Harper offers that perfect balance: structured enough to feel elevated, but relaxed enough to wear every single day.
Made with Lightweight Slub Cotton Jersey
The Harper Tee is made from lightweight 100% slub cotton jersey. Soft, breathable, and garment dyed in Los Angeles, each piece carries a slightly unique color and subtle texture that gets better with every wear and wash.
For select seasonal colors, we also offer the Harper in perlite dyed finishes — adding a rich, vintage-inspired depth to the fabric that gives every piece a one-of-a-kind character.
