420 GSM Heavyweight French Terry Crewneck Sweatshirt | SIGNAL MX Signature
420 GSM organic cotton French terry. Architectural Boxy fit. Peached outer face. Unbrushed loopback interior. Contrast embroidery.
A 420 GSM French terry crewneck sweatshirt with a softly peached exterior and a clear black-and-white signature. SIGNAL MX Signature uses face-only Triple Carbon Peach to refine the dense organic cotton surface with a fine, matte finish. Inside, the integral knitted loops stay unbrushed, no fleece finish or added lining.
A dedicated Architectural Boxy sweatshirt pattern gives you a broad chest, controlled dropped shoulders, and full-length set-in sleeves. The body is not cropped. A 2×2 rib crewneck, 7 cm cuffs, and a 7 cm bottom rib finish the shape with gentle definition rather than a tightly cinched waist.
Raised white tiger-head embroidery contrasts with the black colorway; raised black embroidery defines the white. The detail stays at the left chest, leaving the substantial fabric and proportions in focus.
Wear it over a T-shirt with denim or straight-leg pants. MX adds a softer outer surface to our heavyweight essentials.

Triple Carbon Peach is applied to the outer face only. The jersey-knit face and loopback reverse are formed together as one three-end French terry fabric, not as separate layers. The 420 GSM weight describes that complete main fabric, not an outer layer with extra backing.
MX Signature and BX Armor share a dedicated Architectural Boxy crewneck sweatshirt pattern: a generous chest, controlled dropped shoulders, and full-length set-in sleeves. The ribbed hem gives the lower edge mild shape without turning the body into a cropped or tightly cinched silhouette.
Our size labels are intentionally generous. Start with the body-chest guide, then compare a sweatshirt you own with the finished measurements below. At a boundary between sizes, choose using your preferred proportions and the garment chart rather than assuming a universal size conversion.

How to Measure
Measurement
How to measure
Body chest
Measure around the fullest part of your chest with the tape level and relaxed. This is a body circumference, not a flat garment width.
Half chest
Lay the sweatshirt flat and measure straight across between the underarm/side-seam intersections. Do not use an arbitrary below-armhole offset.
Body length
Measure from the high shoulder point at the side-neck attachment seam to the finished bottom edge. Exclude collar height and include the full bottom rib.
Shoulder width
Measure straight across the back between the shoulder-to-sleeve seam intersections.
Sleeve length
Measure from the shoulder-to-sleeve seam along the relaxed upper sleeve to the finished cuff edge, including the entire cuff. Do not measure from the center back of the neck.
Measure the garment dry and relaxed, without stretching the body or ribs. Use this crewneck sweatshirt chart rather than the T-shirt, Henley, or raglan sweatshirt chart.
For additional guidance, see our Size & Fit Guide.
SIGNAL pairs a solid black or white sweatshirt with raised tiger-head embroidery in the opposite color. The contrast stays focused at the left chest.

Both MX Signature and BX Armor use these contrast pairings. MX has a peached outer face; BX keeps its face unbrushed. Both retain the same unbrushed loopback interior, set-in sleeves, and crewneck sweatshirt measurements.
Our crewneck sweatshirt quality standard sets requirements for the finished French terry and the assembled garment. It covers fabric weight, dimensional change, surface appearance, colorfastness, and twisting after washing.

The standard also covers rib recovery, seam security, loopback integrity, and embroidery appearance. These are product acceptance requirements, not individual measured results for every color, size, or production lot. Single-jersey T-shirt test results do not establish this French terry sweatshirt’s performance.
The dimensional-change program uses 30°C washing and line drying. The separate 40°C laboratory wash-colorfastness method is not a home-care instruction. Always follow the attached care label.
Care step
Instruction
Wash
Machine wash cold, maximum 30°C / 86°F, on a gentle cycle. 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 without stretching the neck or shoulders.
Iron
Use low heat on the reverse only if permitted by the garment care label. Avoid direct heat or pressure on the embroidery and, on MX, the peached outer face.
Always follow the care label attached to your sweatshirt.
Two surface finishes, one crewneck sweatshirt fit. Both series use 420 GSM organic cotton three-end French terry with an unbrushed integral loopback reverse.

Question
Answer
How is SIGNAL MX different from SIGNAL BX?
Both share the same Architectural Boxy crewneck sweatshirt pattern, finished measurements, rib construction, and unbrushed loopback interior. MX has face-only Triple Carbon Peach for a softer, matte outer surface. BX keeps the outer face unbrushed.
Is the inside brushed fleece?
No. The interior has visible, unbrushed knitted loops. The MX peached finish is on the outside and does not turn the reverse into fleece.
What embroidery comes with black and white?
The black sweatshirt has raised white tiger-head embroidery. The white sweatshirt has raised black embroidery. Both SIGNAL colorways use contrast stitching, not VOID’s tonal pairing.
Is the whole sweatshirt 100% cotton?
The main French terry is 100% organic cotton. The neckline, cuffs, and hem use a separate 95% organic cotton / 5% elastane rib blend.
