    Lazer O2 helmet

    I originally bought this helmet at a well known bike shop for £80. My whippet chewed it and I was looking to replace it with the exact same helmet. Tredz price,with a £5 off voucher at the checkout, came in at almost half the price including postage. Excellent value for a great helmet that fits well and looks good.

    Super lightweight helmet

    This is a great value helmet for the price. Fits really well with easy adjustment controls on the top of the helmet. Comes with a handy protective cover which is a bonus.

    Great helmet

    This helmet is great, very comfy.Good adjustability, fits well even with a hat underneath.One downside is that the straps are a little stiff.
