This is not a flat jersey tank. The rib column gives it depth; the spandex keeps the shape from bagging out after arm day, wash, and repeat wear.
◈
Black Out
Spandex recovery helps the black surface stay sharper.
◇
Rib Texture
Vertical rib adds depth without bulk.
▣
Shape Recovery
5% spandex helps the body hold close.
○
Arm Day
High-cut armholes show shoulder and hide side gaps.
Build Notes
Built From Spec.
A construction map for the fit points that matter: rib recovery, high-cut armholes, chest embroidery, and a hem that stays clean after training.
5%
01 / Recovery
Spandex Blend.
The 5% spandex content helps the rib return to shape and keeps the Black Out finish looking tight.
HC
02 / Armhole
High-Cut Line.
Cut to show shoulder and upper back while reducing the side gap that ruins most tanks.
OE
03 / Chest
Power Embroidery.
The Old English chest mark sits at the centerline: a quiet signal for the part of you that kept going.
RIB
04 / Texture
Vertical Rib.
Rib channels create a cleaner line down the torso and keep the tank from reading like a flat undershirt.
