We know that in order to ride properly, your jacket and jeans need to fit properly. Too tight and they could become uncomfortable, causing you to lose concentration, and on waterproof garments it may put additional strain on the tape-sealed seams, allowing water to penetrate.

    Too loose and the clothing could flap whilst riding and the positioning of the armour may move which could compromise your safety.


    Whilst wearing your Triumph T-shirt, pass a tape measure around your back and under your arms. Take the measurement from your broadest part of the chest. This measurement is equal to the jacket size you require, for example 42“ or 104-107cm equals size 42 or Medium jacket. We offer Alpha or Numerical graded fits to cater for the different requirements of our riders, for example a fully functional winter garment is Alpha fit to give more flexibility, with detachable liners, when choosing the necessary undergarments.

    The chest measurements as shown on the size chart show actual jacket measurements. These have taken in to account natural ease for comfort


    Measure around your waist and just above the top of your jeans. Please ensure that you are standing in a comfortable position and do not breathe in, as the jeans need to be comfortable whilst riding.


    Measure around the fullest part of your backside and hips.
