The “Save Your Hide” Guide
What to look for in protective gear
Even
small injuries can cost more than the total worth of your bike…and the
garage you park it in. Some manufacturers use consumer ignorance to
sell products that are very profitable but unsafe. Good gear can make
all the difference. Here are a few tips on how to choose.
Priorities of purchase
Will this save my skin?
Nothing
says irresponsible amateur “squid”, like riding with no protective
clothing. So how do you choose the right gear? When you meet the
pavement unexpectedly you want 4 things, impact protection, abrasion
strength, tear strength and seam strength. Look for pliable dense foam
padding inserts for impact protection. Don't be fooled by armor that is
hard. Armor should absorb impact and the harder the armor the less
impact it will absorb. Look for quality safety lock stitching; your
gear is only as strong as the seams. A simple fall at 30mph can subject
your clothing to more than 100 pounds of tearing force. Fabrics with
similar thicknesses and feels can have vastly different protective
characteristics.
Kevlar
Dupont strikes again
In
order to give it the proper motorcycle abrasion strength Kevlar must be
woven together with other threads, like Dynatec and or Lycra, ei
Schoeller's Keprotec. These are the only suits approved for road racing
other than leather. Some gear manufacturers use small portions of pure
Kevlar as a gimmick. Quality full suits of it can be found. This gear
is lighter, offers greater protection and it breathes. It slides on
pavement the same way as leather and dissipates friction heat better
than leather. Due to its' innate toughness during construction and the
fabrics limited availability it is not widely marketed so it will take
a bit of looking to get one.
Nylon
Only certain grades of nylon will do
Many
names are given to types of Polyester or Nylon to make it sound
impressive. Only Cordura Nylon of 1000 Denier is suitable for
motorcycle gear. Denier refers to the thickness of the fibers in the
weave, higher denier means higher abrasion and tear strength. Be aware
that due to cost, some makers coat their nylon with a layer of
polyurethane that under heavy pavement friction can melt into your skin.
Leather
Who wore it before you did?
Leather
has long been a good protective fabric. However, many variables can
effect its' quality including, the type, age and diet of the animal it
came from. Different methods used to clean, tan and dye the leather
effect it as well. Unfortunately the best way to tell if the garment is
made of good leather is to look at the price tag. Good leather costs
more and that cost is passed on to the consumer. Leather should be worn
snug because when leather folds it's tear strength lowers considerably.
As an organic material leather dries out and looses it's flexibility
over time. In fact each time leather gets wet and dries it can loose up
to 20% of it's tear and abrasion strength. If a good leather
conditioner is used it is still impossible to soften the inside of the
leather properly unless the inner liner can be removed.
