Your armor is earned, not issued.

The Beast Mark Sweatshirt is forged for the relentless. The beast on your back is the weight you carry willingly. The word "RELENTLESS" down your sleeve is the only pace you acknowledge.

Built from brutalist cotton and reinforced at every critical point, this is your second skin for the long campaign. It’s the layer you pull on when the work must be done, when the cold means nothing, and when weak men make excuses.

This isn’t loungewear. This is the uniform for the daily war.

THE BUILD:

Fabric: 100% Ring-Spun Cotton | Strong, rugged, built to survive the grind.

Reinforcement: Taped Neck & Shoulders | No stretch, no sag, no surrender.

Cuffs & Hem: 1x1 Ribbed | Locked in. No retreat.

Construction: Tubular Knit | Durable, efficient, no waste.

Weight: 6.4 oz/yd² | Breathable, unrestricted, built for motion.

CARE + COMMITMENT

Machine wash cold. Preserve the fight in the fibers.

No bleach. Keep your edge sharp.

Tumble dry low. Emerge ready.

Iron low if needed. Discipline in all things.

No dry cleaning. Battle-grade. Machine-wash. Dominate.

Message from the Founder:

This brand wasn’t built to fit in.

I started Berserker Gym because gym gear went soft, fake “performance” with zero backbone.

Every piece we drop is made to take hits, to grind, to last.

No gimmicks. No shortcuts. Just gear forged for people who live the work.

— The Founder, Berserker Gym
