Frequently asked questions

GENERAL
How does it compare to standard activewear?

We got tired of scratchy, chemical-loaded workout clothes, so we made something better. Glas activewear uses plant-based Lenzing™ Modal fabric that's toxin-free and feels amazing on your skin. No harsh chemicals, just soft, clean gear that's actually good for you.
Are any purchases final sale?

We are unable to accept returns on certain items. These will be carefully marked before purchase.
When will I get my order?

All orders containing the CORE (lenzing modal) fabric will dispatch within 48 hours. Both US and International shipping times are 7-10 days.

I'm in between sizes, what should I order?

If you're between sizes, we recommend sizing down. Our fabric offers excellent stretch and support, so you'll still achieve a perfect fit with optimal performance and comfort.
