Base Long-Sleeve T-Shirt keeps it simple with organic cotton comfort and a classic pocket
What Our Gearhead® Experts Are Saying:
"This tee is my go-to for everyday layering. The organic cotton is super soft and breathable, and it holds its shape really well. I especially love the pocket detail—subtle but useful."
We count on the Base Long-Sleeve T-Shirt for that effortless everyday feel. Katin nails the basics with soft, breathable 100% organic cotton in a classic long-sleeve silhouette. It’s the kind of shirt we pull on for slow mornings, road trip layers, and cool coastal strolls—basically any time we want comfort without sacrificing style.
A chest pocket adds subtle function while the range of timeless, pigment-washed colors gives each tee a lived-in look and feel. The fit’s relaxed but never sloppy, making this a staple we’ll keep in the rotation season after season.
