Jackets

Jackets make up the upper half of our two piece suits, but can also be bought alone. Our plain 100 Series jackets are the most popular, and these can be ordered in more generous sizes if you wish to wear them alone, i.e. not connected to trousers. True fitting jackets are only as long and as wide around the waist as the true fit of your made to measure trouser. This can sometimes be deemed insufficient if you really want to wear your jacket separately. Otherwise they will contain a 360 degree zip to connect as required.

Tailored with pre-cut arms that are lifted forward, jackets are anatomically shaped shorter at the front and longer in the back to allow for ultimate comfort when sitting on the bike. The neckline is scooped away from the throat and again at the back of the neck so no matter what position you ride in, there is no resistance to head movement in any direction.

Detachable linings come as standard, as does CE Approved High Performance armour, choices between perforated leather or stretch Kevlar for your inserts and BKS markings as desired. The jacket waistband can be styled plain all round or fitted with a front belt for additional styling, and a reinforced rear section containing 6mm PVC Nitrile padding to add support and protection.

You can upgrade your jacket with more ventilation if preferred and add accessories such as a back protector, Polartec fleece lining and a higher performance limb armour.

Jeans

We refer to these as riding trousers. They form the lower half of our two piece suits and can be bought separately. Our trousers are based on the legs of one piece suits, with the addition of a feature waistband that contains a 360 degree connection zip. Tailored to fit inside boots (although outside fit is an option), trousers come with anatomical shaping at the knees and seat.

The trousers are low cut at the front of the waist allowing for ultimate comfort when sat on the bike. They are shaped to deal with a longer rise around the back, with a waist stretch panel beneath the waistband. This has elasticated sides behind adjuster straps, whilst the centre of this waistband is fitted with 10mm PVC Nitrile padding to add support and protection.

The knees are pre-shaped and we offer an additional leather stretch panel above the kneecap as a free option. Alternatively, we can double shape the knee to provide the same degree of movement with no need for a stretch panel if this is preferred Detachable linings come as standard, as does CE Approved High Performance armour, choices between perforated leather or stretch Kevlar for your inserts, and BKS markings as desired.

You can upgrade your trousers with more ventilation if preferred, and add accessories such as knee sliders, Polartec fleece linings and a higher performance armour.

Joules

Levels of kinetic energy are measured in Joules (J) and when testing Impact Protectors the amount of energy absorbed is measured by the amounts of force in KiloNewtons (KN) passed through and onto the rider. The less force the less injury and anything less than 35KN is deemed acceptable. The European Standard suggests that when hit by an impact equivalent to 50J tested armour will pass CE Approval when 35KN or less is registered as the remaining force felt by the rider.

However, 50J is equivalent to the impacts you might receive when bouncing down the road at 30mph. Just because some impact protectors are CE marked, check again on manufacturers technical details or ask for figures to see just how good it really is.

BKS 4 - layer armour passes at 100J - twice the European Standard, and we know of nothing better offered by our competitors.
