420 GSM organic cotton single jersey. Oversized Relaxed fit. Crewneck. Flat 2.5 cm ribbed hem. Contrast embroidery.

A 420 GSM oversized T-shirt with a distinct ribbed hem and SIGNAL’s black-and-white contrast. EX Essential is made from dense organic cotton single jersey with an unbrushed face, a crewneck, and generous full-length proportions.

Its defining detail is a matching 2.5 cm ribbed hem, about 1 inch high. The hem stays flat and relaxed rather than gathering the body into a sweatshirt-style waistband. It is included in the finished body length, so EX has the same measurements as WX Core.

Dropped shoulders and extended short sleeves complete the Oversized Relaxed silhouette. Raised white tiger-head embroidery contrasts with the black colorway; raised black embroidery defines the white version.

Wear EX untucked to show the change of texture at the hem. Paired with denim or relaxed pants, it brings a considered detail to heavyweight everyday dressing without turning the T-shirt into a cropped or cinched shape.

The EX rib treatment is at the bottom hem, not the crewneck. It adds a distinct finish without extending the WX body length or deliberately cinching the waist. The main body remains single jersey, not French terry.

Our size labels are intentionally generous. Start with the body-chest guide, then compare a T-shirt you already own with the finished garment measurements below. Use the measurements rather than relying on your usual size label.

At the boundary between sizes, choose according to your preferred proportions and the garment chart.

How to Measure

Measurement	Method
Body chest	Measure around the fullest part of your chest with the tape level and relaxed. This is a body circumference, not a garment width.
Half chest	Lay the T-shirt flat and measure straight across between the underarm/side-seam intersections. Do not measure 2.5 cm below the armholes.
Body length	Measure from the high shoulder point at the neck seam to the finished bottom edge, excluding collar height. Include the ribbed hem on EX.
Shoulder width	Measure straight across the back between the shoulder-to-sleeve seam points.
Sleeve length	Measure along the upper sleeve from the shoulder-to-sleeve seam to the finished sleeve opening.

Measure the garment dry and relaxed, without stretching it. For additional help, see the Size & Fit Guide.

SIGNAL puts the contrast in the embroidery. Each garment has a solid black or white body with a raised tiger-head design in the opposite color.

The contrast design is shared across MX Signature, BX Armor, WX Core, and EX Essential. Each series keeps its own surface finish, fit, and hem construction. SIGNAL does not use VOID’s tonal embroidery or STRATA’s additional decorative washed-color finish.

The figures below are REALLY COOL®’s published reference results for the 420 GSM single-jersey material platform. They describe specific material tests, not the weight or performance of every finished garment.

Property	Brand-reported reference	Method reference
Length change after 50 wash cycles	−0.9%	ISO 6330 procedures
Width change after 50 wash cycles	−1.1%	ISO 6330 procedures
Hydraulic bursting strength	1,143 kPa	ISO 13938-1
Pilling resistance	Grade 4–5	ISO 12945-2

These are brand-reported material references, not individual test results for every STRATA color, finish, size, or production lot. The bursting and pilling results should not be read as results measured after 50 washes. Fabric testing does not replace garment-specific care.

Care step	Instruction
Wash	Machine wash cold, maximum 30°C / 86°F. Turn inside out and wash with similar colors. Wash dark colors separately.
Bleach	Do not bleach.

Always follow the care label attached to your garment.

Four series, two fits, one 420 GSM single-jersey foundation. All four STRATA T-shirts come in Burnt Umber and Dark Earth with a controlled washed finish and white contrast embroidery.

Series	Fit	Surface	Bottom hem
MX Signature	Architectural Boxy	Face-only Triple Carbon Peach	Clean self-fabric hem
BX Armor	Architectural Boxy	Unbrushed	Clean self-fabric hem
WX Core	Oversized Relaxed	Unbrushed	Clean folded hem
EX Essential	Oversized Relaxed	Unbrushed	2.5 cm body-color ribbed hem

MX and BX share their finished dimensions. WX and EX share a longer, roomier set of dimensions. The EX ribbed hem is included in the finished body length.

Question	Answer
Does the ribbed hem make EX tighter at the waist?	The hem is designed to sit flat and relaxed. It is not intended to gather the body into a fitted sweatshirt-style waistband.
Is EX longer than WX because of the ribbed hem?	No. The 2.5 cm rib is included in EX’s finished body length. EX and WX share the same finished garment measurements.
Does ribbed hem refer to the neckline?	No. EX has a crewneck. The ribbed detail refers specifically to the 2.5 cm bottom hem; the short sleeves have self-fabric openings.
