Assero Textile Glove FAQ
In hot and humid conditions most gloves quickly smell bad as their leather begins to rot. Oddly, nearly all summer motorcycle gloves are made from leather. The problem is leather can not be washed or get wet without an inevitable loss of strength. Since Assero's Keprotec gloves are 100% synthetic they can be washed without harm. Our glove care instructions and more information about Assero's unique textile motorcycle gloves can be found below.
How do I wash my gloves?
Our Keprotec gloves should be hand washed lukewarm or placed in a clothes washing machine set to cold, 30C, or 40C wash. Use natural soap flakes. Under NO circumstances should bleach be used, nor any washing product that contains chlorine. Chorine rapidly degrades Kevlar fibres. After washing, give the gloves a final rinse in fresh water.
How do I dry my gloves?
It’s best to line dry your gloves in the shade on a hot day. Of course, that is not always possible. For fast drying, hang the gloves on a line.They will dry many times faster than leather gloves. You can dry them in direct sunlight but beware that UV eventually degrades all fabrics. Whatever you do, do NOT put them in a hot clothes drier or you risk melting the fabric. In practise we find that when we have been caught in a tropical rain-shower our Assero gloves dry very quickly on the bike once the storm has passed.
Should I remove the liner?
The liner is NOT designed to be removed. The glove should be washed in one piece.
Are the Assero Helios Professional gloves waterproof?
No, Assero's Helios Professional gloves are air-permeable not waterproof. We found that all types of waterproof and breathable membrane got hot and sweaty on a typical humid day in Thailand. The use of air-permeable fabrics allows air to flow throughout the glove which keeps the wearer's hands dry and comfortable all day.
What are Assero Helios Professional gloves made of?
The body of our gloves is Keprotec, made by one of the world's leading textile companies, Schoeller of Switzerland. It is a unique fabric specifically developed for motorcycle apparel. Keprotec is a weave of Nylon and Kevlar with some Elastothane which creates an abrasion resistant stretch fabric.
The "dotted" fabric we use on the exterior of our gloves is SuperFabric. Created by Dr Young-Hwa Kim, founder of Higher Dimension Materials, Inc., SuperFabric is a purpose built abrasion resistant fabric. We use SuperFabric to reinforce areas where, in the event of an accident, contact with the ground is most likely and where we want the glove to slide rather than grip.
For the glove liner most companies use a non-protective Nylon liner. For our Helios Pro glove we felt that we could increase both comfort and protection through the use of a knitted Dyneema liner. Dyneema is an Ultra-High Molecular Weight Polyethelyene (UHMWPE), with both strength for weight and abrasion resistance up to fifteen times greater than carbon steel. It is one of the most abrasion resistant materials known to man (UHMWPE panels are used for synthetic ice rinks). What's more, at a molecular level Dyneema is hydroscopic which makes it very comfortable against the skin. Unlike Kevlar, Dyneema is not susceptible to acid or alkali, and it can be washed repeatedly with no loss of strength. We regard it as an extra margin of safety should the Keprotec layer become damaged.
On and around the knuckle protectors we use Cordura fabric and high density rubber. Cordura is made of N6.6 polyamide, which is the strongest, most stretchy form of "high tenacity Nylon". It offers very good abrasion resistance.
How do I know that my Assero gloves will stay on in an accident?
We have spent a great deal of time studying and testing a solution to this problem. Most motorcycle gloves are not adequately secured. You can test this easily. Put on your gloves, fasten them, and then ask someone to yank them off by the finger-tips. If they can come off while fastened, they can come off in an accident.Assero's solution is a retention strap which completely encircles the wrist. Fastened correctly the glove will not pull off. Period.
What type of thread is used to construct Assero's gloves?
For all stitching, we use bonded Nylon thread from Coates, the world’s largest thread manufacturer. The European standard for motorcycle gloves requires a minimum seam strength of 15 Newtons per millimetre, which is approx 1.5kg per mm.. The thread we use for prototyping, where we need to assemble, test and then tear down a glove, is estimated to give a seam strength of 1.75kg per mm. The estimated seam strength of the heavier Coates Nylbond thread we are using in the pre-production and production gloves for our customers gives an estimated seam strength of 2.5kg per millimetre. This results in seams with a good margin of safety, 66% stronger than the European standard.
How does the Assero Helios Professional glove compare to other motorcycle gloves?
The world of motorcycle gloves is dominated by the use of leather. We have learned from experience that leather gloves tend to degrade quickly in humid climates. In a hot weather glove we believe that the disadvantages of leather are too great. It is impossible to wash leather without a loss of strength. Without washing leather gloves in hot weather begin to smell very bad. And from a practical perspective, getting leather gloves wet is inevitable in tropical countries where sudden rainshowers are commonplace.The world's best synthetic fabric for motorcycle wear is Schoeller's Keprotec. It does not suffer significant degradation in strength after repeated washing or rainstorms. It is designed to provide significant abrasion resistance.

What are European Standards EN 13594:2002 and EN 13594:2012 and why are they important?
EN 13594:2002 and EN 13594:2012 are important because they provide an objective way to measure and compare the performance of motorcycle gloves. These European Standards are recognised worldwide as the highest standard of independent evaluation of motorcycle gloves. Gloves that are marked as having passed all the tests within EN 13594 can be considered "Personal Protective Equipment (PPE)."
The European Standard is sub-divided into various levels of performance. Amongst other characteristics EN 13594:2002 presents minimum standards for tear strength, abrasion resistance, impact cut resistance, seam and slide fastener burst strength, and specifies the location and attachment of impact protectors, clothing restraint, fit and ergonomic standards. EN 13594:2012 specifies two levels of protection, Level 1 of which is of lower overall protection compared to the earlier 2002 standard, and Level II.
Our plan was to send the Assero Helios Pro gloves to SATRA in the UK for independent testing to EN 13594 at the end of January 2015. Two barriers have cropped up: the new EN 13595:2012 test has still not been ratified, and the recent change in the value of the Swiss Franc throws into question whether Keprotec gloves will be viable in the future. Once we have more information, we update this page.
