Product Insights

The Corecotton™ Muscle T-Shirt by INNER SELF is a lightweight 4-5 oz 100% cotton jersey tank with raw-cut sleeves and hem that maximize ventilation, freedom of movement, and an athletic silhouette, but requires sizing up due to 3-5% shrinkage on hot wash and careful washing to preserve the reflective star logo and slow edge curling; it is an exclusive Simons capsule designed for runners, offering a tradeoff between breathable comfort for light activity and sweat absorption during intense workouts.

Verified claims

Sizing
Size up if between sizes; 100% cotton shrinks 3-5% on first hot wash.
Fit
Wide armholes and raw sleeves maximize ventilation and freedom of movement.
Fabric weight
Light 4–5 oz cotton jersey hangs with minimal weight even when sweaty.
Mobility
Raw cut sleeves reduce chafing and tension for easier overhead lifts.
Aging
Raw cut edges curl gently with wear; wash inside out to slow fraying.
Styling
Raw hem anchors an athleisure outfit with biker shorts and sneakers.
Ventilation
Unhemmed sleeves maximize side ventilation for cooling during runs.
Moisture handling
Lightweight 4-5 oz 100% cotton jersey absorbs sweat but minimizes slapping and enhances cooling via raw-cut armholes.
Safety placement
Reflective star on back improves rear visibility to drivers in traffic.
Reflective print durability
Cotton jersey grips reflective print well; gentle wash prevents peeling.
Brand exclusivity
Exclusive to Simons via i.FiV5; a Montreal-designed capsule from 2024 startup INNER SELF.
Moisture management
Buyers report that the cotton fabric holds sweat and becomes heavy during intense workouts.
Outfit formula
Styled with high-waisted black biker shorts and retro sneakers for a sporty-street look.
Care
Inside-out gentle wash and air drying prevent reflective logo peeling and preserve safety visibility.
Shrinkage
100% cotton jersey shrinks 3-5% on hot wash; size up if between sizes.
Movement range
Deep armholes and raw-cut sleeves prevent fabric drag and binding during full arm extension.
Silhouette
Oversized armholes deliberately expose shoulders and upper lats for an athletic look.
Breathability
Lightweight cotton and deep armholes provide breathability for light activity but not heavy sweating.
Brand text
Hidden prints INNER SELF, THE ESSENCE OF FREEDOM, and RUNNING TEAM communicate brand's runner-empowerment mission.
Reflective logo
Reflective star logo on back enhances low-light visibility and symbolizes personal achievement.
Exclusive capsule
