So you can trust what's touching your skin...
Synthetics have you questioning if your activewear is actually good for you. Ours definitely is.
Meet Glas Active—choose between our plant-based Lenzing™ Modal or organic cotton, both naturally non-toxic and designed to feel like a second skin. This isn't just another workout outfit. It's activewear that actually works with your body, not against it.
Core is made from a lenzing modal, no more petroleum based fabrics.
Your skin is your body's largest organ, and it deserves better than synthetic fabrics loaded with harsh chemicals and toxins. Polyester and nylon contain thousands of chemicals that can cause skin irritation, hormone disruption, and allergic reactions—not exactly what you want pressed against your body during a workout. These synthetic materials trap heat and bacteria, leading to breakouts, rashes, and persistent odors that won't wash out.
At Glas Active, our fabrics are rigorously tested and naturally free from these harmful substances. Instead, you get plant-based fibers that are naturally breathable and hypoallergenic, designed to work with your body rather than against it.
Traditional activewear relies on petroleum-based synthetic fibers that shed microplastics with every wash, polluting waterways and harming marine life. Glas Active takes a different path. Our plant-based fibers are renewable, biodegradable, and produced using sustainable practices that require less water and energy than synthetic manufacturing. We use non-toxic dyes and small-batch production to minimize waste. When you choose natural over synthetic, you're helping reduce the fashion industry's environmental impact, one workout at a time.
