Mossimo Supply Co Sweater — Classic Knitwear for Everyday Wear
Our Mossimo Supply Co sweater delivers year-round layering versatility in a lightweight cotton-blend knit. We engineered this crewneck with a relaxed fit through the chest and sleeves, so it sits comfortably over tees or button-ups without bunching. The ribbed hem and cuffs hold shape through repeated wear, while the mid-weight fabric regulates temperature in both air-conditioned offices and cool evenings.




We knit every Mossimo Supply Co sweater from a 60/40 cotton-polyester yarn that balances softness and durability. Pure cotton sweaters feel luxurious initially but tend to stretch out at pressure points — elbows, cuffs, and the lower hem — after a few weeks of regular rotation. Adding 40% polyester filament gives the knit memory, so the ribbing snaps back to its original dimension even after a full day of wear.


Relaxed Fit & Layering Versatility
Sizing Philosophy
Our crewneck follows a true-to-size relaxed fit, meaning the chest and waist measurements match standard sizing charts without adding extra room for “athletic” or “slim” cuts. A size Medium measures 22 inches pit-to-pit when laid flat, which translates to 44 inches around the chest — generous enough to accommodate a dress shirt underneath without pulling at the buttons, yet trim enough to wear over just a tee without looking boxy.
Sleeve Length & Mobility
The raglan-style shoulder seam runs diagonally from the collar to the underarm, giving your arms a wider range of motion than a traditional set-in sleeve. This design choice prevents the fabric from binding when you reach forward to type or lift objects. Sleeve length is cut to break at the wrist bone, so cuffs sit naturally without riding up your forearm or covering your hands.

Care Instructions & Longevity
Machine wash the sweater in cold water on a normal cycle with like colors. We recommend turning the garment inside-out before washing to minimize friction against the knit face, which keeps the surface smooth longer. Tumble dry on low heat or lay flat to air dry — both methods work equally well with this blend, though air drying slightly extends the life of the elastic in the ribbing.
Avoid fabric softener, which coats polyester fibers and reduces their natural wicking ability. The cotton-poly blend already feels soft against skin without chemical treatment. If you notice minor pilling after several months of wear, a fabric shaver removes the pills in under a minute. For detailed maintenance guidance across different knit types, refer to our sweater care reference that covers everything from storage to stain removal. Store the sweater folded on a shelf rather than hanging it, since prolonged hanger storage can stretch the shoulders out of shape.

Your Questions About Our Sweaters
The crewneck sweater is a lighter-weight knit without a hood or front pocket, designed primarily for layering under jackets or wearing solo in moderate temperatures. Our hoodies use a heavier fleece construction with a lined hood and kangaroo pocket, offering more warmth and a sportier silhouette. Both share the same cotton-poly blend for durability and easy care.
The 60/40 cotton-polyester blend resists shrinkage when washed in cold water and tumble-dried on low heat. Polyester fibers stabilize the cotton, preventing the dramatic shrinkage that occurs with 100% cotton knits exposed to high heat. We pre-shrink the fabric during manufacturing, so the garment dimensions remain consistent through repeated wash cycles.
The mid-weight knit works well in air-conditioned offices and cool summer evenings but may feel too heavy for outdoor wear in hot, humid climates. The cotton-poly blend breathes better than synthetic fleece, so it transitions comfortably between spring and fall. For peak summer months, consider pairing it with shorts for evening beach walks or keeping it in your car for over-cooled indoor spaces.
Crewnecks layer cleanly over tees and sit higher on the neck, making them ideal for casual wear and colder weather. V-necks showcase the collar of a dress shirt underneath and create a longer visual line down the torso, which some people prefer for dressier looks. Both styles use identical fabric and construction — the choice comes down to personal style preference and what you plan to wear underneath.
Our relaxed fit runs true to standard sizing charts. If you’re between sizes and prefer a closer fit for layering under jackets, size down. If you want extra room to wear thicker shirts underneath or prefer a looser drape, size up. The raglan sleeves offer flexibility in both shoulder width and arm length, so most people find their usual size works without adjustment.
The mid-weight knit provides adequate warmth in temperatures ranging from 50°F to 65°F when worn over a long-sleeve tee or henley. Below 50°F most people layer it under a jacket or coat. The cotton-poly blend blocks wind better than loose-knit 100% cotton but doesn’t offer the insulation of a fleece-lined hoodie or quilted jacket.
The polyester content in the rib-knit trim helps it retain elasticity longer than pure cotton ribbing. After six months of regular wear, you may notice minimal relaxation at the cuffs, but the hem typically holds firm because it experiences less stress. Washing in cold water and air-drying extends the life of the elastic fibers. If cuffs do loosen slightly, a warm iron applied to the ribbing while damp can temporarily tighten them.
