Black thermal long sleeve T-shirt with a slim fit and stylish design. - Model Name: GUERILLAZ THERMAL LS TEE - Color: Black - Size: S Purchased from the official website. It looks good worn on its own or as an inner layer. It's easy to move in and breathable, so I think it's also good for gym wear. I'm selling it because the size didn't fit. I'm open to price negotiations. Thank you for looking. corteiz thermal uk street
