This Berserk pump cover is an oversized gym t-shirt cut to be worn over your working layer, not as a second skin. The fit is deliberately roomy: soft cotton knit, dropped shoulders and a breathable body you keep on around the session. The Berserk print is inspired by the manga and screen-printed to last.
Berserk pump cover: features and specs
- Fit: oversized, dropped-shoulder cut that frees your range of motion on every lift.
- Fabric: soft cotton knit, breathable straight on the skin from warm-up to last set.
- Design: Berserk anime print, screen-printed to hold wash after wash.
- Use: a true pump cover in the gym, and a street piece outside it.
- Colors and sizes: several colorways, dark tones matching the Berserk mood best, S to 2XL.
- Layering: the natural top layer over a compression tee, or under a hoodie in winter.
Why lifters wear a pump cover
A pump cover does the opposite job of a compression tee: it keeps the muscle warm through the ramp-up and covers the pump between sets, then comes off when you want to check the work. Dropped shoulders free presses and pulls without clinging when you sweat, the dense knit drapes clean and the collar holds its shape. It is the loose half of a proper set of berserk gym clothes.
Pump cover or compression tee?
Take this oversized cut if you want coverage, warmth and a streetwear silhouette. Take the Berserk compression shirt if you want muscle support and a second-skin fit under the bar. Most lifters run both: compression underneath, pump cover over the top — the two halves of a set of berserk workout clothes.

Size guide and care
Take your usual size for a moderate oversized look that drapes clean, or size up for the full pump-cover silhouette. Available in several colors, sizes S to 2XL. Machine wash cold, inside out to protect the print, and air dry.
Frequently asked questions
What size should I take for a pump cover?
Your usual size gives a moderate oversized drape; size up for the full baggy pump-cover look.
Is it compressive?
No, the opposite: this is a loose cotton tee. For muscle support, wear a compression top underneath.
Can I wear it outside the gym?
Yes, the dropped-shoulder cut and dark colorways work as streetwear as much as gym wear.

Product information
Care. Machine wash at 30 °C max, inside out, no bleach and no fabric softener: softener clogs technical fibres and kills their moisture-wicking. Air dry only, never tumble dry. Do not iron directly on a print.

Choosing the wrong size despite the guide is not a product defect.
