One of the best helmets available for kite buggying - I've used it for a few years for paragliding and buggy racing. Superb protection, wide field of vision and ultralight. Helmet bag included.
Never dropped, crashed or damaged, although a few minor scuffs and the odd tiny chip from use plus a tiny bit of rust around the metal rivet (from beach salt) This is the more expensive carbon blue effect model, costing £130 :
Size XL is good for at least 62cm head circumference.
£40 (plus postage if required)
