The RC Outdoor Supply Lassen Collection is a series of utility-driven garment styles created by the brand with comfort and capability in mind to work well for everyday adventures. The collection puts the Lassen Overshirt and the Lassen Pant in the spotlight that are both purpose-built for adventure, and are each crafted with a heavyweight brushed cotton twill fabric.

The Overshirt spotlights a relaxed fit with cargo pockets on both the front and the sleeve, while embroidered eyelets at the underarm accommodate ventilation and tape-slotted buttons maximize durability. The Pant has zipped closures at the sides and on the front alongside flap pockets on the rear to maximize storage, while an RCOS hood on the waistband works well for hanging essentials.
