When developing the 2017 products series we wanted to come up with something new and truly unique. Something that would further increase the safety of our product. An example of our dedication is our design of the plastic shoulder sliders that began over 2 years ago in spring 2015. As a result we are now absolutely confident that we have achieved these design goals of a unique, safe and highly functional motorcycle garment.

We know there is nothing like it; when you start the engine and feel the indomitable force that pushes you forward. Adrenalin goes through you and you want to be faster and perhaps, the fastest! But before you go fast you need high quality professional grade equipment. That’s exactly what the TT Replica Nitro is as its features & functions are taken straight from the top line 4SR racing suits.

As a subtle touch the fluorescent colours are not only fashionable but will catch the eye of every other road user for added safety.

Our biggest development from the previous 4SR race glove, is the use of stingray skin to protect the scaphoid area. Stingray skin is highly abrasion-resistant and stable at high temperatures, providing an all-round better solution than existing plastic scaphoid protectors.

Our Superbike glove has a pre-curved shape to give the rider a perfect feeling on the handlebars and reduces the problem of blistering hands, we have also introduced a very fine Pittards leather on the palms, this is 2 times more durable than Kangaroo leather.

Another improved safety feature is our flexible leather connection between the riders ring finger & little finger, a delicate area that is prone to damage during a crash. This feature is doubled up with an extra layer of 100 % DuPont ™ Kevlar®.

Racing gloves 96 Stingray are equipped with anti - shocksystem made by Viscofoam material, this absorbs the impact from hitting the asphalt. This smart material which gradually deforms on impact, is used in the production of the palm, wrist, the main knuckle and fingers.

If you like the previous model 96 Gloves, you will love this Stingray model.

• Leather gloves made of goatskin, special Anilin Digital design

• Palms and scaphoid protectors made of 100 % stingray skin
• Viscofoam® protectors over wrists, joints and knuckles ensure alleviation of an accidental impact in a crash situation by spreading the power of the impact more evenly over the surface
