Extend your T-shirt's lifecycle by looking after it with care.
- Machine-wash gently at 30°C/86°F

- Hang to dry, don’t tumble-dry
- We recommend to air-dry instead of washing it after every use
- Use mild detergent and no fabric softener (we recommend choosing environmentally - & health friendly detergents)
- The shirt can shrink up to 5% after the first wash due to its natural origin (Note that we considered this shrinkage in our sizing guide. So when you feel that the shirt is a bit too long when trying it on for the first time, please consider it may shrink up to 5% after your first wash.)

Other care tips
+ Wash less: Our unique fabric requires less washing due to its natural bacteria- and odor-inhibiting properties.
+ "End of life" and disposal tips: If it is still in good shape - swap with friends, resell as second-hand, repair or bring to your local tailor for repair. If it is very worn out and can no longer be used, best to bring it to a local textile collection or recycling station. It can even be composted, but make sure you understand how to compost in the right way.
Questions?
What is the Alvarius Performance Tee made from?
100% TENCEL™ Lyocell — a high-tech fibre derived from sustainably grown eucalyptus trees. It’s breathable, naturally antibacterial, and completely plastic-free.

Is it really plastic-free? Even the threads?
Yes. Every part of this shirt — from the fabric to the threads to the packaging — is certified plastic-free. No polyester. No elastane. No greenwashing.
How does it perform during workouts?
It wicks sweat, regulates temperature, and resists odour. It moves with you, doesn’t cling, and dries fast. Built for real performance; not just lounging.
If you prefer a more snug fit on any of these T-shirt fits, we recommend sizing down one size, for an even looser fit, going up one size.
What size should I get?
Our fit is athletic but not tight. If you're between sizes or prefer a looser fit, size up.
View size guide here.
How long will it last?
This tee is made to go the distance. TENCEL™ Lyocell is a premium fibre that retains its shape and feel, wash after wash. Treat it with care and it’ll stick around longer than any synthetic.
How is this different from “eco-friendly” shirts I’ve seen elsewhere?
Most so-called sustainable activewear still contains 80–90% plastic (polyester, nylon, etc). Ours doesn’t. Zero plastic. Full performance. That’s the difference.
