Description

Tired of boxy cuts, tight sleeves, and collars that cave? This shirt is the upgrade. Athlete-tapered through the torso with room where you lift (shoulders/chest) and clean where you lean (waist). Our luxe bamboo blend is insanely soft, breathable, and naturally temperature-regulating so you stay cool under pressure. It moves with you, drapes clean, and keeps its colour wash after wash. Look strong. Feel sharp. Zero compromise.

Sizing + Fit

Most customers size up one from their normal size.


Athletic taper + stretch = clean lines

 

Everyday comfort: Size up one for a relaxed, post-gym, all-day fit.

 

Sharp, close-to-body look: Go true to size.

 

Between sizes / broad up top: Size up one for extra room in chest & shoulders.

 

Tip: If you’re unsure, choose the larger size. Easy exchanges.

Material + Care Instructions

Crafted from a premium bamboo-spandex blend, our fabric is breathable, insanely soft, and built to move with you. It’s moisture-wicking, thermoregulating, and naturally odor-resistant — so you stay cool, dry, and sharp all day long.

 

• Cold wash only
• Wash inside out with similar colours
• Do not bleach
• Hang dry or lay flat — avoid the tumble dryer
• Cool iron if needed (do not iron print or labels)

Premium fabric deserves premium care — treat it right, and it’ll stay sharp wear after wear.

Fantastic shirt, compliments always

This shirt is awesome! I get so many compliments when I wear it out, from both guys and girls. I wear it all the time now. Its so soft and really easy to move in. It is a snug fit, I recommend going up one size from your normal shirt size for the best fit. Highly recommend!

FAQ

Does this shirt run true to size?

Yes — it’s designed to fit true to size for an athletic build.
If you have broad shoulders, a big chest or prefer a slightly more relaxed fit, we recommend sizing up. Always check the size chart for the best fit. Most of our customers size up one from their usual t-shirt size.

How does this compare to regular fitted shirts?

Most “slim fit” shirts are just smaller everywhere.
This shirt is designed specifically for athletic frames — room in the shoulders and chest, clean through the waist, and no boxy billowing.

Will it shrink after washing?

No — the fabric is pre-shrunk and engineered to hold its shape.
Wash cold and either air-dry or tumble dry on low to maintain the fit.

What’s the fabric made from?

Our Bamboo Muscle Shirt is made from a premium bamboo blend designed for softness, stretch, and breathability.
It’s naturally temperature-regulating, moisture-wicking, and comfortable all day.

Is this suitable for casual and dressier occasions?

Yes. It’s refined enough for dinners, dates, and nights out — but comfortable enough for all-day wear.
That’s the balance it’s built for.

Can I return or exchange it if it doesn’t fit?

Absolutely. We offer 30-day hassle-free returns and free exchanges so you can shop with confidence.
