Principal partners SBOBET are giving West Ham United supporters the opportunity to win a 2012/13 Macron home or away shirt in a special prize draw.

To be in with a chance of pulling on one of the Hammers' new Barclays Premier League shirts, all you have to do is join and place a bet with SBOBET here anytime between now and 31 August to be entered into the prize draw.

When registering use promotion code WHUJ and ten lucky winners will have the choice of either a home or away shirt. Over-18s only. Terms and conditions apply.

The new home shirt showcases the traditional claret body with sky blue sleeves redesigned with a vintage style. The shirt features a stylish claret knitwear 'corean' neck collar with a sky blue insert, embellished by a stitched yellow cross recalling the symbolic Hammers logo.

A second embossed Hammers logo on the back of the shirt means nobody will be in any doubt who you support, while sky blue inserts on the flank define the profile of the shirt and shape its form. The sleeves combine the sky blue colour with a claret piping profile.

The away shirt is a classic navy V-neck with an asymmetrical claret and blue design, with the famous crossed Hammer detail. There is also further extensive detail, with 'West Ham United' stitching on the back of the collar.

Following fans' feedback at the club's Supporter Advisory Board, the new away shirt has also been designed so it is 'Moore than just a football kit'. It has been made to be worn for comfort whether it is for leisure on a day out or wearing to cheer on the Hammers.

For those fans too young to enter the SBOBET competition, you can buy your 2012/13 Macron home or away shirt here.
