RoadMuse Tees FAQs

What size should I order?

Check our size guide above for exact measurements. Comfort Colors 1717 runs slightly oversized — most people size down one from their usual.

What is Comfort Colors fabric and why does it feel different?

Comfort Colors uses a garment-dyeing process where the shirt is dyed after it's constructed, giving it a naturally soft, broken-in feel from day one. The 6.1 oz heavyweight cotton gets even softer with every wash.

Will the print crack or fade after washing?

No — we use high-quality printing that's designed to stay vibrant through hundreds of washes. Turn your shirt inside out before washing in cold water to keep the colors at their best for longer.

How do I wash and care for my tee?

Machine wash cold, inside out, on a gentle cycle. Tumble dry on low or hang dry. Avoid high heat — it's the only thing that shortens the life of any garment-dyed shirt.

Can I give this as a gift — will it arrive in time?

Absolutely — RoadMuse tees make one of the best car gifts out there. Standard shipping takes 5–7 business days.

Do you offer plus sizes?

Yes — Comfort Colors 1717 is available from Small through 4XL. Check the size guide above for exact measurements before ordering.
