The Essential Expression of Pure Heavyweight Jersey.
The heavyweight tee in its most effortless form. SIGNAL WX Core is a 420 GSM oversized T-shirt designed around the natural drape, room, and character of dense organic cotton jersey.
Crafted from 100% organic cotton high-density single jersey, WX Core retains the fabric's original unbrushed surface.
The substantial material weight gives the silhouette presence, while its Oversized Relaxed pattern allows for natural movement and drape.
Relaxed by Design. Essential by Nature.
WX Core features a generously proportioned chest, dropped shoulders, longer sleeves, and a full-length, non-cropped body.
The silhouette is intentionally relaxed, offering volume without excessive construction or unnecessary detailing.
A standard folded jersey hem, finished with double-needle stitching, maintains a clean and continuous line from the body to the lower edge.
Unlike EX Essential, WX Core does not feature a separate ribbed-knit hem. Its finishing approach preserves the simplicity of the original jersey construction.
SIGNAL Collection. Defined by Contrast.
Raised tiger-head embroidery introduces the collection's signature visual identity through two contrasting color combinations:
The embroidered emblem adds recognizable dimension while allowing the substantial cotton jersey and oversized proportions to remain central.
Built on the 420 GSM Foundation.
WX Core shares the same high-density organic cotton jersey platform as the other REALLY COOL® T-shirt series, incorporating GOTS Integrity Wash processing and the material-development standards behind our True Shape Memory concept.
The tested jersey platform has demonstrated measurable dimensional stability, material strength, and resistance to pilling.
A heavyweight essential, easy to wear and easy to make your own.
【Signature Finishing & Construction】
WX Core — The Relaxed Expression
Essential Shoulder Construction
The shoulder construction follows the garment's natural Oversized Relaxed proportions.
The design allows for a naturally relaxed shoulder line, complementing the overall silhouette without adding unnecessary structure.
Clean Neckline & Everyday Construction
A traditional ribbed crew neckline provides a familiar finishing detail.
The overall construction supports the garment's relaxed shape without introducing unnecessary structural treatments.
The intention is straightforward: substantial cotton jersey, balanced proportions, and clean everyday wear.
WX Core approaches heavyweight jersey through simplicity, relaxed proportions, and clean construction.
Built on the shared 420 GSM organic cotton jersey foundation, it removes unnecessary finishing complexity to allow the material and silhouette to define the garment.
Natural Unbrushed Jersey
The dense 420 GSM organic cotton single jersey retains its original unbrushed surface.
Unlike MX Signature, WX Core does not undergo Triple Carbon Peach mechanical brushing.
The natural knit texture remains visible, preserving the substantial feel and authentic character of the cotton material.
Oversized Relaxed Fit
A wider chest, generously dropped shoulders, longer sleeves, and a full-length body establish the WX silhouette.
The design prioritizes natural volume, comfortable movement, and a relaxed everyday fit.
Standard Clean Hem
WX Core features a traditional folded jersey hem, approximately 1.5 cm wide, finished with double-needle stitching.
The hem is constructed from the same jersey material as the body, preserving a consistent surface appearance from top to bottom.
This clean construction distinguishes WX Core from EX Essential, which features a refined 2.5 cm ribbed-knit hem.
SIGNAL Contrast 3D Embroidery
Our signature raised tiger-head emblem introduces recognizable dimension through two contrasting combinations:
The embroidery creates a distinctive visual signature while preserving the simplicity of the oversized silhouette.
The Essential Is the Expression.
From the natural unbrushed cotton surface to the standard clean hem, WX Core is defined by removing complexity rather than adding it.
