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.

Standard Utility

Balanced. Clean. Everyday layering. Neither slim nor oversized — sits naturally on the body with room to move.

Tailored Athletic

Close to the body. Built to move. Minimal excess. Designed for performance without restriction.

Relaxed Layering

Designed to go over base layers. Room through chest and shoulder. Comfortable without being shapeless.

Chest

Relax your arms at your sides. Measure around the fullest part of your chest, keeping the tape level across your back.

Waist

Measure around your natural waistline — the narrowest part of your torso, typically just above the navel. Keep the tape snug but not tight.

Hip

Stand relaxed with feet shoulder-width apart. Measure around the fullest part of your hips and seat.

Sleeve Length

With your elbow bent, measure from the center back of your neck, across your shoulder, down to your elbow, and then to your wrist.

Front Length

Measure from the highest point of the shoulder, at the base of the neck, straight down to where you want the hem to fall.

Inseam

Measure from the crotch seam straight down the inside of the leg to the bottom of the hem. For shorts, this is the finished length of the inner leg.

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.

Why We Made This

We made the Heavyweight Sweatpant to be a more refined take on an everyday essential. Something comfortable enough to live in, but considered enough to feel put together beyond just off-duty wear. We wanted it to feel familiar in function, then elevated everywhere else. A substantial fabric, a cleaner silhouette, and details that quietly improve how it moves and wears over time. Built with articulated knees, a comfortable waistband, and a tailored fit, it is a staple reworked with more intention. The Heavyweight Sweatpant is an everyday piece, elevated through material, function, and finish.

Materials

Every Heavyweight Sweatpant starts with 415 GSM 100% organic Peruvian Tanquis cotton french terry, chosen for its softness, structure, and substantial hand feel. Knit from long-staple yarns, the fabric wears comfortably, breathes well, and develops more character with time. Garment dyed for a lived-in feel from day one, it is grown, spun, and sewn entirely in Peru under GOTS-certified and Fair Trade standards. The result is a sweatpant that feels grounded, durable, and refined in everyday wear.

Key Features

The Heavyweight Sweatpant is cut with a clean, tailored silhouette that feels easy on body while still looking considered. The 415 GSM french terry gives it a more substantial weight, while articulated knees add comfort and ease of movement throughout the day. An elastic drawstring waistband provides an adjustable fit, and the internal right-hand stash pocket adds utility without adding bulk. Finished with ribbed cuffs for a cleaner shape, it is built to feel comfortable, wear easily, and settle in over time.
