420 GSM Heavyweight Boxy Long-Sleeve Henley | SIGNAL BX Armor
420 GSM organic cotton single jersey. Architectural Boxy fit. Three-button Henley. Unbrushed face. Clean open cuffs.
A 420 GSM boxy long-sleeve Henley that keeps the texture of dense cotton in focus. SIGNAL BX Armor combines an unbrushed organic cotton single-jersey face with clean, straight self-fabric cuffs and a reinforced three-button placket.
Generous chest room, controlled dropped shoulders, and a straight, non-cropped body establish the Architectural Boxy silhouette. Full-length set-in sleeves finish without ribbed wrist bands or elastic. Mobilon shoulder reinforcement and dimensional stabilization support the intended proportions.
The contrast is in the chest embroidery: white on the black Henley, black on the white. Button colors are coordinated separately, with Dark Espresso Brown on black and Warm Ivory Cream on white. Fasten the round Henley neckline for a clean line, or leave it open for a more relaxed look.
Wear it with denim or straight-leg pants for a contemporary essentials wardrobe built around substantial cotton and considered proportions.

BX keeps the jersey face unbrushed and finishes the sleeves with a clean, turned edge made from the same fabric as the body. Its three functional buttons and rectangular box-X placket base are shared with MX. SIGNAL uses solid black or white, without STRATA’s additional decorative washed-color finish.
MX Signature and BX Armor share the same Architectural Boxy Henley measurements: generous chest room, controlled dropped shoulders, and a straight, non-cropped body. They differ in both the fabric surface and the wrist finish: MX has ribbed cuffs; BX has clean self-fabric open cuffs.
Our size labels are intentionally generous. Start with the body-chest guide, then compare a Henley or similar long-sleeve top you own with the finished measurements below. At a boundary between sizes, use 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 garment 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 neck attachment seam to the finished front bottom edge, excluding neck-band height.
Shoulder width
Measure straight across the back between the shoulder-to-sleeve seam points.
Total sleeve length
Measure along the upper sleeve from the shoulder-to-sleeve seam to the final edge. Include the entire MX ribbed cuff or BX turned finish. This is not a center-back-neck measurement.
Measure the garment dry and relaxed, without stretching it. Compare sleeve length as well as chest width, since shoulder placement and arm length affect where the cuff sits.
For additional guidance, see our Size & Fit Guide.
SIGNAL pairs a solid black or white Henley with raised tiger-head embroidery in the opposite color. Button colors are coordinated separately from the embroidery.

Warm Ivory Cream
Both MX Signature and BX Armor have three functional buttons in the colors shown above. On the white Henley, Warm Ivory Cream describes the buttons, not the garment or the embroidery. On the black Henley, the buttons are Dark Espresso Brown, not white.
SIGNAL uses contrast embroidery rather than VOID’s tonal pairing, and does not receive STRATA’s additional decorative washed-color treatment.

Garment Care
Machine wash cold (maximum 30°C).
Turn the garment inside out before washing.
Wash with similar colors; wash dark colors separately.
Do not bleach.
Do not tumble dry.
Reshape gently and line dry in the shade.
If ironing is permitted by the care label, use low heat on the reverse side and avoid direct contact with the embroidery.
Handle the button placket gently. Avoid pulling on the buttons or applying direct heat or pressure to the buttons and reinforced placket. Follow the attached care label for any additional handling instructions.
Two Henley series, one Architectural Boxy size chart. Both use 420 GSM organic cotton single jersey, a reinforced three-button placket, and full-length set-in sleeves. The differences are the fabric surface and the cuff construction.

Question
Answer
What does clean cuff mean on BX?
The sleeve ends in a straight, turned opening made from the same jersey as the body. There is no separate ribbed wrist cuff or elastic band.
Does BX use a different size chart from MX?
No. Both share the same nominal chest, body length, shoulder width, and total sleeve length. The outer surface and cuff construction differ; choose the finish you prefer.
Are the white Henley’s buttons black to match its embroidery?
No. The white garment has black contrast embroidery and Warm Ivory Cream buttons. The black garment has white contrast embroidery and Dark Espresso Brown buttons.
Is the BX surface brushed or decoratively washed?
The jersey face is unbrushed and does not receive Triple Carbon Peach. SIGNAL also does not receive STRATA’s additional decorative washed-color treatment.
