Chest is measured across the garment, so double it for the full chest.
This is a boxy, heavyweight cut and it runs large. If you prefer a closer fit, take the size below.
Measurements are the supplier's own, and may vary by up to 2cm.

THE GARMENT

• Comfort Colors 1717, garment-dyed in the USA
• 100 percent ring-spun cotton, 6.1 oz (207 gsm), so it hangs rather than clings
• Garment-dyed, which is why the colour looks lived-in from day one and softens further rather than fading
• Relaxed boxy cut. It runs large: size down for a closer fit

Colours: Ivory, White, Pepper, True Navy, Moss and Black.

Printed to order, never held in stock, so nothing is made that nobody wants.
