GSM means grams per square metre, a measure of fabric weight. Our signature jersey weighs 420 GSM, substantially heavier than a conventional 200–220 GSM T-shirt jersey.Weight influences how fabric feels and drapes. It is one part of quality, alongside fibre, construction and finishing.Read: What Does 420 GSM Mean? · 420 GSM vs 300 GSM
No. Our signature 420 GSM organic cotton single jersey is the foundation of our core heavyweight jersey range. Other garments, including our independently developed utility and outerwear styles, may use different materials and construction.Each product page specifies its own fabric composition, weight where applicable, fit and finishing details.
SIGNAL, VOID and STRATA share one design foundation and the standards they are built to. SIGNAL pairs the garment with contrast embroidery. VOID keeps the embroidery tonal. STRATA adds a controlled washed finish in Dark Earth and Burnt Umber, with subtle colour variation as part of its look.
Our core T-shirt system begins with two distinct patterns.MX Signature and BX Armor share an Architectural Boxy silhouette and reinforced structural construction. MX adds our Triple Carbon Peach brushed surface, while BX retains the natural face of unbrushed jersey.EX Essential and WX Core share a Full-Length Oversized Relaxed silhouette. EX adds a refined 2.5 cm ribbed-knit hem, while WX features a clean folded hem.Other garment categories may follow their own pattern and construction specifications.
Our core T-shirts are designed as unisex garments with intentionally generous proportions.For MX Signature and BX Armor, size M is developed around a wearer who typically chooses men's XL in many US or European brands, while creating our intended Architectural Boxy fit.WX and EX follow a different Oversized Relaxed pattern and should be selected using their own finished garment measurements.The two patterns have different finished measurements, so compare our garment measurements with a piece you already own, or write to us and we will recommend a size within 24 to 48 hours.
Our signature heavyweight jersey uses GOTS-certified organic cotton and has been evaluated through documented textile testing, including dimensional stability, bursting strength and pilling resistance.We provide methods and product-specific details so that material claims can be understood in context.
Price reflects differences in construction, surface finishing and design.Within our core T-shirts, WX presents the foundation in its most direct form. EX adds a refined ribbed hem. BX introduces reinforced structural details and dimensional stabilization. MX adds the Triple Carbon Peach finishing process.Collections and other garment categories have their own production and finishing requirements.
For our core cotton jersey, machine wash cold at 30°C maximum with similar colors, inside out. Avoid bleach and tumble drying. Reshape gently and dry in the shade.Always follow the care label of your individual garment, as materials and trims vary by product.
