420 GSM organic cotton single jersey. Oversized Relaxed fit. Crewneck. Full-length body. Clean folded hem.

A 420 GSM oversized T-shirt with a full-length body and a clean, uninterrupted hem. SIGNAL WX Core uses dense organic cotton single jersey to give its roomy proportions substantial drape, while keeping the outer face unbrushed.

The Oversized Relaxed pattern is wider and longer than our Architectural Boxy fit. Dropped shoulders and extended short sleeves complete the relaxed silhouette, while a crewneck keeps the neckline simple. A folded self-fabric hem finishes the body without a separate ribbed band.

SIGNAL adds a focused contrast: raised white tiger-head embroidery on black, or raised black embroidery on white. The chest detail stands apart from the solid body color without taking over the silhouette.

Wear WX untucked with denim, cargos, or relaxed pants. It is the clean-hem choice in our oversized premium essentials. EX Essential offers the same finished measurements with a 2.5 cm ribbed hem.

WX lets the wider, longer pattern and dense cotton do the work. It shares its finished measurements with EX, but keeps a folded jersey hem. Its relaxed construction does not use the dedicated Mobilon shoulder reinforcement or stabilization system specified for MX/BX.

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.
Dry	Do not tumble dry. Gently reshape and line dry in the shade.
Iron	Use low heat on the reverse only if permitted by the garment care label. Avoid direct heat or pressure on the embroidery.

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 SIGNAL WX have a ribbed hem?	No. WX Core has a clean folded self-fabric hem. The 2.5 cm ribbed bottom hem belongs to EX Essential.
How does WX fit compared with MX and BX?	At the same labeled size, WX is 5 cm wider in flat half chest, 4 cm longer in the body, 2 cm wider across the shoulders, and 2.5 cm longer in the sleeves.
Should I size up for an oversized look?	The oversized proportions are already built into the pattern. Start with the body-chest guide and compare the finished measurements with a T-shirt you own before choosing your size.
