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
The fitted silhouette pairs with wide armholes and raw-cut sleeves, reducing underarm tension while allowing full arm movement.
Fabric weight
Light 4–5 oz cotton jersey won't pull or slap against the body like heavyweight cotton, but it still absorbs sweat and can feel heavy during intense workouts.
Mobility
Raw cut sleeves reduce underarm and shoulder tension, and the deep armholes eliminate fabric drag during overhead presses, pull-ups, and running strides.
Aging
Raw cut edges curl gently with wear; wash inside out to slow fraying.
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 inside-out washing helps prevent peeling, though some wear is normal over time.
Brand exclusivity
Exclusive to Simons via i.FiV5; a Montreal-designed capsule from 2024 startup INNER SELF.
Moisture management
The 100% cotton jersey is not moisture-wicking; it absorbs sweat and becomes heavy during intense workouts, so it's best for low-impact activity or casual wear rather than high-sweat training.
Outfit formula
Styled with high-waisted black biker shorts and retro sneakers for a sporty-street look.
Care
Washing inside out on a gentle cycle and air drying help prevent reflective logo peeling and preserve safety visibility; some wear is normal with frequent machine drying.
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.
Fabric opacity
This tank is available only in Black and Emerald/Kelly Green, both dark shades, and the 100% cotton jersey is opaque enough that neither should be sheer under bright gym lighting.
