Avengers, ASSEMBLE!! Show your love for Earth's Mightiest Heroes with this excellent piece of official Marvel merchandise. This officially branded design comes on a fitted T-shirt. These garments are mostly 100% ringspun cotton - however please be aware that the colours with a heather finish (Sport Grey, Dark Heather etc) are a polycotton blend (exact percentage of polyester varies dependant on colour). Please note this T-shirt comes with a slim fit style for a tighter, more fitted look - please refer to the size guide in the pictures for reference. If you're after a looser fit, we'd recommend ordering one size up from your usual size.
