All Helmets

Helmet size is measured around the circumference of the head starting in the middle of the forehead. Start around 1 cm above the eyebrows then around the head just above the ear to the lumpy part on the back of the head (not the medical term I know!) then back past the opposite ear to the start point.
The fit should be a snug fit when new, as the inner comfort liner will give out between 5%-10%.
A lose fitting helmet will not protect the head correctly in the event of an accident!
Measurement should be taken in centimetres please refer to the conversion chart below.

All Glove Sizes in Inches:

Glove measurements are taken across the widest part of the palm (palm side only) in centimetres Please see the conversion chart.
Two rules apply to glove fitment that contradict each other, summer/lightweight gloves should be tight for maximum feel and to allow for stretch, winter/waterproof gloves should be a little large which allows air to be trapped so keeping the hands warmer, but not so large feeling is lost or they can be removed too easily.

Hand Measurement	Alpha Glove Size
6 - 6.5	XS
6.5 - 7.5	Small
7.5 - 8.5	Medium
8.5 - 9.5	Large
9.5 - 10.5	XL
10.5 - 11	XXL
11 - 12	XXXL

Jacket and suit sizing is based on chest measurements.
The fit should ideally be snug so any body armour will stay in place, but not so tight as to restrict movement.
If using in the wet or cold it may be worth leaving enough room to fit a fleece or thick jumper underneath.

Trousers and jean measurement is based on waist size.
As with the jackets it is advisable to have the trousers or jeans fitting as snugly as possible to keep any body armour firmly in place also bearing in mind that if they are leather they will stretch out.
