All measurements are garment measurements laid flat. Chest and waist are measured across, not around. If you're between sizes, we recommend sizing up.
We don't design everything to fit the same. We design each piece to fit its purpose. Every silhouette is intentionally built for how it's meant to move, layer, and live.
Product fit reference
All product measurements on SMBL are garment measurements laid flat — not body measurements. If you're between sizes, we recommend sizing up. Questions? We'll size you right or we pay the return.
High-output trail days demand focus. Most shorts either overcomplicate the ride or fall apart when the pace picks up. We wanted something lighter, more breathable and more comfortable under effort, so we stripped it back to what matters: lightweight stretch fabric that moves without resistance, targeted airflow to dump heat on the climb, secure storage that stays quiet in motion and a dialed fit that doesn’t shift mid-ride. The result is a short that disappears when you’re deep in it. Because when the trail gets loud, your gear shouldn’t.
Adjustable waistband with Cobrax® snap closure for a secure, dialed fit under load. Knee pad compatible construction with a tapered leg that stays clear of the drivetrain. Articulated patterning built for aggressive riding positions and unrestricted movement on technical terrain. Aquaguard® 2-way zips, bellowed cargo pockets, and secure internal storage keep essentials stable and protected. Bonded front hems reduce bulk and eliminate friction where it matters most.
Built with a lightweight 162gsm stretch fabric from Toray, one of the world’s most trusted technical textile makers. The recycled nylon construction delivers breathable durability with the right amount of stretch to move naturally on the bike. Ventilated panels release heat on long climbs while moisture-wicking fibers keep the short dry under sustained effort. Tough enough for trail contact, stable enough to hold its shape ride after ride.
