420 GSM French Terry Sweatshirts & Hoodies
Set-in crewnecks, raglan sweatshirts, pullovers, and full-zip hoodies built from 420 GSM three-end French terry with an unbrushed loopback interior.
GSM stands for grams per square meter and describes fabric weight. Our 420 GSM Signature Jersey is a dense single jersey used in T-shirts and Henleys; our 420 GSM Signature Loopback Jersey is a separate three-end French terry used in sweats. Weight is one part of a garment's character, alongside its knit, finishing, and fit.Read: What Does 420 GSM Mean? · 420 GSM vs 300 GSM
No. Our Signature Jersey and Signature Loopback Jersey platforms use 420 GSM fabrics. STRATA Woven includes 340 GSM cotton-twill cargo trousers and a 300 GSM cotton-twill track jacket. Check each product page for its own material and weight.
SIGNAL uses contrasting embroidery. VOID uses matching tonal embroidery.STRATA explores Burnt Umber and Dark Earth through washed finishes on selected styles and patterned woven construction on independent designer pieces.
420 GSM Signature Jersey: High-density organic cotton single jersey forms our heavyweight T-shirts and Henleys. Shape, drape, and the character of the fabric face define each style. 420 GSM Signature Loopback Jersey: Three-end French terry combines a clean jersey-knit face with integral, unbrushed loops on the reverse. It forms our sweatshirts, hoodies, sweatpants, and sweat shorts, not a separate jersey layer bonded to a lining. STRATA Woven: Independent designer pieces in non-stretch compact cotton twill. Panelled Cargo Trousers use 340 GSM fabric; the Curved-Panel Zip-Up Track Jacket uses 300 GSM woven fabrics. Neither belongs to the MX/BX series system.
On our core T-shirts, MX Signature and BX Armor share a structured boxy pattern; MX has a finely peached face and BX keeps the face unbrushed. WX Core and EX Essential use an oversized relaxed pattern; EX has a 2.5 cm ribbed hem. Not every product category is offered in all four series.
Start with the size chart for the specific garment. Our T-shirts, sweatshirts, hoodies, sweatpants, and woven outerwear use different fit blocks and measuring points. Compare the finished measurements with a similar garment you already own.
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.
Materials, construction, finishing, and functional details vary by style. A heavyweight single-jersey T-shirt, a lined woven jacket, and an eight-pocket cargo trouser require different components and work. Each product page explains what goes into that garment.
