Stiff Person Syndrome Spasms Are My Superpower – Chronic Illness Awareness Shirt

Embrace your strength and sense of humor with this bold Stiff Person Syndrome shirt. Featuring the eye-catching zebra-patterned “SPASMS” and the empowering slogan “Spasms Are My Superpower,” this tee honors the resilience it takes to live with SPS. Soft, comfortable, and designed for everyday wear—even on the stiffest days.

I’ve personally tried this shirt, and it’s super soft — like “wait, am I even wearing a shirt?” soft. It’s unisex, so it runs large for women — and good news: it barely shrinks, if at all, even after a wash and dry. Lightweight, comfy, and breathable enough for flare days.

This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!
