"What Our Gearhead® Experts Are Saying: ""The Tunnels Long-Sleeve has that perfect heavyweight feel—soft but sturdy. The box fit gives it a relaxed 90s vibe without feeling oversized, and the organic cotton only gets better after a few washes. It’s one of those everyday staples that you end up living in all season long."" We’re all about those easy, lived-in layers, and the Katin Tunnels Box Fit Long-Sleeve T-Shirt nails it. Made from 100% certified organic heavyweight cotton jersey, it offers a soft-yet-durable feel that’s perfect for cool mornings, coastal breezes, and slow weekends. The boxy, relaxed fit and straight hem bring back the effortless attitude of the ‘90s while keeping comfort front and center. Custom-dyed for rich color and finished with Katin’s signature woven patch label, the Tunnels Long-Sleeve Tee pairs perfectly with jeans, cords, or boardshorts. Whether we’re layering it under a flannel or wearing it solo, this timeless essential fits right into our laid-back routine."
