"Dirt Research Collective" is the premier institution for empirical studies in geotechnical engineering and advanced soil composition analysis (specifically, finding the exact ratio of loam to clay needed to 'braappp'). Our field teams specialize in the mechanical disruption of terrain to construct monumental dirt sculptures—often referred to 'big ole booters.' Through thousands of hours of rigorous, sweat-drenched, shovel-based research, we have perfected the art of creating predictable, yet exhilarating, two-wheeled projectile physics. From measuring root-to-dirt ratios for optimal compaction to analyzing the precise velocity needed to clear 'that gap,' we are dedicated to advancing the complex science of having a very sktchy, very good, time.
Washed Out Collection: Ride the Line Between Dirt and Sand
Most shirts need a hundred washes and a few crashes to feel this good. This one started there. Our garment-dyed vintage tee brings that lived-in, "stolen from a 90s surf shop" aesthetic for those more laid-back moments. Off the bike, on the sand, and officially unreachable.
The unique seam shading and tonal variations mean no two shirts are identical—just like your line down the mountain. Built with a heavy-duty, relaxed fit that survives both flat landings and beach bonfires, it’s the ultimate staple for when the bike is on the rack and the sun is dipping low.
Feel:Soft as a coastal breeze, tough as a rock garden.
Fit:Relaxed/Boxy for maximum airflow.
Vibe:100% laid back, but still SKTCHY
The Details: This vintage-style t-shirt has that soft, worn-in look people love from day one. The garment-dyed finish creates subtle color variations, making every piece feel unique and relaxed. It’s an easy everyday tee that works just as well styled up or worn casually.
