How to measure
Chest
Under the arms, across the fullest part, tape level front and back. Arms down, breathe out. A finger's width of slack, no more.
Head
About a centimetre above the ears, across the middle of the forehead, round the widest part at the back. Snug, not tight.
Between sizes
Tee: take the smaller one. Puffer: take the larger one, or contact us for guidance based on the measurements above.
Still unsure
Email us your chest measurement and what you'd normally wear. We'd rather answer that than process a return.
Returns
Thirty days, unworn, tags attached. If the size is wrong, send it back and we'll swap it. Details on the Shipping & Returns page.
