This Invisible Merino Wool T-shirt is a lifesaver for Hong Kong’s brutal humidity!
It’s super breathable and doesn’t stick to your skin at all, even when you’re dripping sweat after a heavy workout.
The absolute best part is that it is completely odor-free. I’ve been working out in mine for a few days now and it genuinely does NOT smell at all. Not even a tiny bit! So comfortable and low-maintenance! Highly recommend!

The Power of Merino
Merino Wool is a protein-based fiber, specifically, keratin, just like your hair. Each fiber’s natural crimp traps air, creating insulating pockets for exceptional thermoregulation. Its “dual naturel” also gives it incredible moisture control—the fiber feels dry on the outside, yet absorbs vapor from your skin.
Dissolvable Packaging
Our groundbreaking #INVISIBLEBAG2.0 along with transparent pricing tag. This is made from 95% bio-based content derived from sugarcane. Every part is dissolvable, compostable, and biodegradable. Simply dissolve them in water to make a positive impact.
