VOID BX Armor - 420 GSM Heavyweight Wide-Leg Sweatpants

Material Note:

The main fabric is 100% organic cotton French terry. The pocket bags use a separate, lighter organic cotton single jersey for comfort and reduced bulk.

The waistband contains elastic and a cotton drawcord. Fabric composition refers to the main shell rather than every component of the finished garment.

• 420 GSM French Terry - Weight With Purpose

Our 420 GSM organic cotton French terry gives these straight-leg sweatpants their substantial feel and clean appearance.

The fabric combines a dense, jersey-like outer face with natural, unbrushed cotton loops on the inside. Unlike traditional brushed fleece, the loopback reverse retains its knitted texture.

The result is a heavyweight cotton fabric designed to feel comfortable while giving the relaxed silhouette a more defined shape.

• Clean Unbrushed Face - The BX Armor Character

BX Armor preserves the clean, natural character of our 420 GSM French terry knit.

Without the Triple Carbon Peach finish used in MX Signature, the outer face retains its direct cotton texture and dense, understated appearance.

The inside remains naturally unbrushed, with visible cotton loops that distinguish French terry from traditional brushed fleece.

Paired with the generous wide-leg silhouette, the substantial fabric gives the relaxed shape a sense of weight and presence.

The result is a straightforward expression of material and form — clean in texture, substantial in feel and defined by proportion.

• VOID Tonal - An Exercise in Restraint

VOID explores understated color and tonal detail.

Black pairs a deep black surface with black raised embroidery. White takes the same approach with white-on-white detailing.

Both colorways focus on the relationship between texture, material and silhouette, without intentional fading or washed color effects.

• Relaxed Wide-Leg Fit - Volume With Balance

Designed with generous room through the seat and thighs, the wide-leg silhouette maintains its fullness past the knee and down to the open hem.

Unlike a straight-leg cut, this shape carries more width throughout the leg, creating a relaxed, flowing proportion without relying on a dramatic flare at the bottom.

The full-length opening allows the fabric to fall naturally over footwear, while the substantial 420 GSM French terry gives the wider shape a sense of weight and presence.

The result is intentionally roomy, with a clean silhouette that feels considered rather than exaggerated.

• Everyday Construction - Details That Matter

A neatly turned wide open hem completes the silhouette, allowing the full leg width to fall naturally over footwear. Tonal raised tiger-head embroidery and the signature REALLY COOL® side label add restrained branding.

Our 420 GSM heavyweight straight-leg sweatpants are developed around confirmed quality standards covering fabric weight, wash performance, waistband recovery and everyday wear.

The focus goes beyond fabric weight alone. We also assess how the finished garment holds its shape, how the elastic waistband responds to repeated movement and how the pockets and seams perform during wear.

A substantial fabric is only the beginning.

The waistband is assessed for support and recovery, the pockets for everyday use, and the leg seams for a balanced appearance after movement and washing.

These are the confirmed performance and acceptance standards for this product. They define the quality requirements rather than reporting individual numerical readings for every finished garment.

We also assess zipper movement and front alignment, helping the hoodie maintain a balanced appearance whether worn closed or open.

• Relaxed Wide-Leg Fit

The REALLY COOL® MX Signature and BX Armor wide-leg sweatpants share the same dedicated wide-leg pattern, developed for the weight and natural drape of our 420 GSM organic cotton French terry.

Both offer generous room through the seat, thighs and knees, with a wide opening that carries the volume through the full length of the leg.

The fit is intentionally roomy, with a balanced silhouette that falls naturally over footwear without an elasticated ankle cuff.

Unlike our Straight-Leg Sweatpants, the Wide-Leg design provides additional width throughout the leg, rather than simply widening at the hem.

MX Signature and BX Armor share the same finished measurements. Their difference lies in the outer surface finish, not the fit.

• Size Reference

Our bottoms use a separate sizing system from our T-shirts, sweatshirts and hoodies.

Choose your size based on your natural waist and full hip measurements, rather than assuming your usual top size will be the same.

Our 420 GSM heavyweight bottoms are built around a shared organic cotton French terry foundation, offered in two distinct series: MX Signature and BX Armor.

Both use the same 3-end French terry construction, with a dense outer face and an unbrushed loopback interior.

Within each style, MX and BX share the same fit and finished measurements.

• MX Signature - The Tactile Expression

A controlled Triple Carbon Peach finish gives the outer fabric a softer, matte character, while the interior cotton loops remain unbrushed.

• BX Armor - The Structured Expression

An unbrushed outer face preserves the direct character of the knitted cotton, paired with the same substantial 420 GSM French terry and straight-leg shape.

Straight-Leg Sweatpants: A clean, relaxed leg that falls naturally from the seat to the open hem. Balanced proportions for everyday wear.

Wide-Leg Sweatpants: A fuller silhouette with additional volume through the seat, thigh, knee and leg opening.

Sweat Shorts:A relaxed, above-knee proportion with a wide open leg and substantial heavyweight cotton feel.

All three styles belong exclusively to the VOID collection, available in Black and White with tonal embroidery.

The choice begins with silhouette, followed by the MX or BX surface finish.

Different proportions. The same commitment to material and considered construction.
