Before you purchase, if you have any questions please email customerservice@jackmurphy.ie Different manufacturers and different styles result in various fit sizes, therefore, Jack Murphy has an easy returns policy. If your purchase does not fit correctly,  please return the item back to us within 60 days for exchange or refund. If you still have specific questions about the fit of an item or measurement guide please email our customer service team. If you prefer a refund we will only refund the items you are returning but not for the shipping costs.
