420 GSM organic cotton single jersey. Architectural Boxy fit. Clean unbrushed face. Reinforced shoulders.

A 420 GSM structured boxy T-shirt that keeps the texture of dense cotton in focus. STRATA BX Armor is made from heavyweight organic cotton single jersey with a clean, unbrushed face and a controlled washed finish.

Its Architectural Boxy proportions balance a generous chest with a compact, non-cropped body. Dropped shoulders and wide short sleeves create a defined outline, while internal Mobilon reinforcement and dimensional stabilization support the shoulder structure and finished shape.

Burnt Umber brings warm, oxidized brown tones; Dark Earth offers a deeper brown expression. Both feature raised white tiger-head embroidery, a ribbed crewneck, and clean self-fabric hems.

Pair it with denim or tailored pants when you want a heavyweight tee with visible knit character rather than a peached surface. BX shares its fit with MX Signature, offering a different tactile expression within the same contemporary essentials collection.

BX preserves the natural definition of the jersey face. Its washed color is a STRATA finish, not a brushing treatment. You get the same architectural proportions as MX, with a more direct cotton texture and no added peached surface.

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.

STRATA gives the same heavyweight jersey garments a different color expression. A controlled wash introduces subtle tonal depth rather than aggressive acid washing or heavy distressing.

Color
Appearance
Chest embroidery
Burnt Umber
Warm, oxidized orange-brown with restrained washed depth.
White contrast
Dark Earth
Deep brown with controlled tonal variation.
White contrast
Both colors feature raised white tiger-head embroidery on the left chest. The color name identifies the garment shade, not the embroidery color.

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

Bleach	Do not bleach.

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

Question	Answer
Is STRATA BX brushed or unbrushed?	Unbrushed. The jersey face does not receive the Triple Carbon Peach treatment. Its washed color variation comes from the separate STRATA finish.
Does BX fit differently from MX?	No. BX Armor and MX Signature share the same Architectural Boxy pattern and finished measurements. The principal difference is the fabric surface.
Is STRATA BX acid-washed?	No. STRATA uses a controlled washed finish for restrained tonal variation. It is not designed with aggressive acid washing, heavy distressing, or random bleached patches.
