STRATA EX Essential - 420 GSM Washed Oversized T-Shirt with Ribbed Hem
Relaxed by Design. Refined in Detail.
STRATA EX Essential is a 420 GSM oversized T-shirt crafted from GOTS-certified organic cotton single jersey. Its full-length Oversized Relaxed silhouette features a roomier chest, naturally dropped shoulders, and extended sleeves for an easy, substantial drape.
Built on the same pattern as WX Core, EX Essential introduces a distinctive 2.5 cm ribbed hem. The tonal rib-knit finish adds a considered structural detail while maintaining a relaxed, straight hemline without the constriction of a sweatshirt waistband.
The unbrushed cotton jersey preserves the natural definition of the dense knit, while STRATA's additional controlled washed finishing introduces subtle tonal variation and material depth.
Available in Burnt Umber and Dark Earth, each T-shirt is finished with raised white 3D tiger-head embroidery and a discreet woven side label.

The Refined Expression - 2.5 cm Ribbed Hem
EX Essential is defined by a visible 2.5 cm ribbed-knit hem, designed as a subtle architectural finish to our Full-Length Oversized Relaxed silhouette.
Made in a matching tonal color, the ribbed construction introduces a refined textural contrast against the dense single jersey body.
Unlike a conventional sweatshirt waistband, the hem is designed to remain relaxed and straight, preserving the natural drape and full-length proportions of the garment.
Unbrushed Jersey - Natural Material Definition
EX Essential retains the unbrushed surface of our 420 GSM organic cotton single jersey, allowing the fine knit structure and substantial fabric weight to remain visible.
STRATA Washed Finish - Material Depth
STRATA introduces a separate controlled washed finishing process, creating restrained tonal variation and a material-led appearance.
Burnt Umber: A warm, deep oxidized brown inspired by mineral and earthen surfaces.
Dark Earth: A darker, grounded brown with understated tonal variation.
A Shared Silhouette, A Distinct Finish
EX Essential shares its base pattern with WX Core. The distinction lies in the hem: EX features a refined tonal ribbed finish, while WX maintains a standard clean hem.
Both preserve the same intended full-length Oversized Relaxed proportions.
Our 420 GSM organic cotton jersey has been evaluated through laboratory testing for dimensional stability, fabric strength, pilling resistance, and color fastness.

Built Around Measurable Standards
Beyond its substantial 420 GSM fabric weight, our organic cotton jersey is evaluated for dimensional stability, fabric strength and surface appearance.
Results reflect laboratory-tested samples and their specified testing conditions.
Actual garment performance may vary with wear, laundering, and care practices.
Full-Length Oversized Relaxed Fit - EX Essential / WX Core
Designed for a longer, roomier silhouette with dropped shoulders, extended sleeves, and a natural, relaxed drape.
EX Essential and WX Core share the same Oversized Relaxed base pattern and finished garment proportions.
EX Essential introduces a refined 2.5 cm ribbed hem, while WX Core features a clean, approximately 1.5 cm double-needle stitched hem.
Both maintain a deliberately oversized, full-length silhouette without a cropped proportion.
Size Reference
Our sizing is intentionally generous. Size M is developed around wearers who typically choose men's XL in many US or European brands, with additional volume and length built into the Oversized Relaxed pattern.
Because this fit is roomier than our Architectural Boxy series, we recommend comparing the finished measurements rather than relying on conventional size labels.

How to Measure
Measure around the fullest part of your chest with the measuring tape level and relaxed.
For the most accurate fit comparison, measure a T-shirt you already own and compare the chest width, body length, shoulder width, and sleeve length with our finished garment measurements.
Understanding Our Fits
MX Signature / BX Armor - Architectural Boxy: A more compact full-length proportion with structured chest volume, controlled dropped shoulders, and wide straight sleeves.
WX Core / EX Essential - Oversized Relaxed: A longer, wider silhouette with extended sleeves, relaxed shoulders, and naturally flowing volume.
Both pattern blocks are intentionally generous and designed as unisex garments.
The difference is in proportion, structure, and drape, not simply a larger size.
