SIGNAL BX Armor - 420 GSM Heavyweight Raglan Crewneck Sweatshirt

The main body is made from organic cotton French terry. Rib trims use a separate organic cotton and elastane blend for fit and recovery.

• 420 GSM French Terry - Substantial by Nature

This sweatshirt begins with our 420 GSM organic cotton French terry, developed with a smooth outer surface and unbrushed cotton loops on the inside.

Unlike a brushed fleece sweatshirt, the reverse retains its knitted loopback character. The result is a substantial fabric with a distinct feel and appearance, designed for standalone wear and easy layering.

• BX Armor - The Natural Cotton Surface

BX Armor highlights the natural character of our 420 GSM French terry. Its clean, unbrushed outer face retains the original appearance of the dense cotton knit, giving the sweatshirt a direct, substantial feel.

Paired with SIGNAL's contrasting black-and-white embroidery, this creates a distinctive everyday sweatshirt where the material, relaxed raglan shape, and graphic detail work naturally together.

• SIGNAL Contrast Expression - Defined by Detail

SIGNAL brings a graphic approach to our everyday essentials. Black and white are paired in deliberate contrast, making the raised tiger-head embroidery a distinctive part of the design.

Black with White Embroidery: A deep black sweatshirt with raised white tiger-head embroidery. The contrast gives the chest graphic a clear, recognizable presence while keeping the overall look clean.

White with Black Embroidery: A crisp white sweatshirt with raised black tiger-head embroidery, creating a bold contrast against the light cotton surface.

Both colorways share the same 420 GSM French terry, MX Signature Triple Carbon Peach finish, and Architectural Boxy Raglan Fit.

Two essential colors. Two expressions of the same contrast-led design.

• Raglan Sleeves - A More Relaxed Shoulder Line

The defining feature of this sweatshirt is its raglan sleeve construction. Diagonal seams extend from the crew neckline toward the underarms, replacing the traditional shoulder seams of a set-in sweatshirt.

This gives the shoulders a more relaxed appearance while maintaining the generous body and balanced proportions of our Architectural Boxy Fit.

The result is a distinctive everyday crewneck that feels easy to wear, whether styled on its own or layered over a T-shirt.

• Architectural Boxy Fit - Room Without Excess

Designed around a dedicated heavyweight raglan sweatshirt pattern, the fit is wide through the chest, with full-length sleeves and a balanced body length.

A structured 2×2 ribbed neckline, 7 cm ribbed cuffs, and a 7 cm bottom hem complete the shape without sharply tightening the wrists or waist.

The silhouette is intentionally roomy, but not cropped or excessively oversized.

Our 420 GSM French terry is developed around defined quality standards for weight, wash performance, surface appearance and colorfastness.

Quality Beyond Fabric Weight

Fabric weight is only one part of a well-made sweatshirt. We also consider how the material responds to washing, how its surface holds up to wear, and how the finished garment maintains its intended shape.

These figures are the defined performance and acceptance standards for the French terry program, not individual measured results for every finished colorway.

• Architectural Boxy Raglan Fit

The REALLY COOL® MX Signature and BX Armor raglan crewneck sweatshirts share the same dedicated Architectural Boxy pattern, developed specifically for the weight and feel of our 420 GSM French terry.

The body is generously cut through the chest, while diagonal raglan seams create a relaxed line from the neckline to the underarms.

Full-length sleeves and structured ribbed trims complete a balanced, roomy fit that is neither cropped nor excessively oversized.

• Size Reference

Our size M is designed for the body proportions of someone who commonly wears a men's XL in many US or European brands, while delivering the intended REALLY COOL® boxy fit.

This is a fit recommendation, not a universal size conversion. For the most reliable fit, compare the finished measurements with a sweatshirt you already own.

Unisex Size Guide - Recommended Body Chest

Finished Raglan Sweatshirt Measurements (cm / inch)

Measurements are taken with the garment laid flat and relaxed.

• Half Chest: Measured straight across the chest.

• Body Length: From the high shoulder point to the finished bottom hem, including the 7 cm rib.

• Raglan Sleeves: Extend from the neckline to the finished cuffs, rather than from conventional shoulder seams.

Our 420 GSM heavyweight raglan crewneck sweatshirts are developed in two series: MX Signature and BX Armor.

Both share the same organic cotton French terry foundation, Architectural Boxy Raglan Fit, unbrushed loopback interior, and ribbed construction. The difference is how the outer surface looks and feels.

• MX Signature - The Tactile Expression

Our Triple Carbon Peach finish gives the outer surface a softer, matte character while preserving the natural unbrushed loopback interior.

• BX Armor - The Structured Expression

An unbrushed exterior retains the original character of the knitted face, offering a more direct fabric feel with the same substantial weight and raglan fit.

Both series are available across SIGNAL, VOID, and STRATA.

SIGNAL brings contrast embroidery. VOID keeps the branding tonal. STRATA introduces washed earth-inspired colors.

Choose the finish that feels right for you.

The fit remains the same.
