  • Defeet Un-D-Shurt Long

    The Defeet Un-D-Shurt Long is designed to wear under a cycling jersey, and is made to be thin and fit the shape of the rider. With nifty thermal properties that allow the rider to stay cool on less demanding stages of the journey but also not to over heat on the more challenging stages, this Un-D-Shurt is a winner!

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
