In 2003, Pierre-Henry Servajean created ARMALITH®, a specialty fabric obtained by combining cotton fibers with UHMWPE (ultra-high molecular weight polyethylene) fiber - previously used only in aerospace, military and off-shores industries.
In 2015, ARMALITH®2.0 was born - softer, stretchier, more technologically advanced, and more fashionable - leading to Pierre-Henry’s new project: BOLID'STER®.
WITH A CLASSIC FIT - AND AVAILABLE IN STONE WASH, RAW DARK INDIGO, OR BLACK - JEAN’STER IS TIMELESS. THESE JEANS ARE AS COMFORTABLE AS THEY ARE LONG-LASTING.
WITH A PERFECTLY SCULPTED FIT AND HIGH QUALITY MANUFACTURING, THE RAW INDIGO JENY'STER IS 'PROTECTIVE CHIC' FOR FEMALE BIKERS AND ADVENTURERS.
MODERN TECH MEETS VINTAGE APPEAL. REMOVABLE CE PROTECTORS & EXCEPTIONAL RESISTANCE MAKE THE RAW INDIGO RIDE'STER THE BEST ALLY FOR THE DARING.
A MODERN, SLIM-FIT JEAN WITH BOLID'STER'S NEW ARMALITH®2.0 SKIN WATER-REPELLENT FABRIC. STAY SAFE, STAY STYLISH, STAY DRY.
AN UNPRECEDENTED INNOVATION IN THE WORLD OF JEANS AND THE WORLD OF BIKING.
Imagine fashionable jeans protecting motorbike and scooter riders in case of a fall on the road.
Contrary to other technologies (Kevlar®-lined jeans, leather, ballistic polyamide, etc.) this is the first and only single layer of fabric that provides high-performance protection in case of abrasive impact (20m of slide on the road without a hole under 13595-2 certification conditions) and provides the comfort and quality of the most beautiful and fashionable jeans - even in summer, even off the bike.
BOLID'STER JEANS ARE MADE OF
*ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE
*UHMWPE COMPARED TO KEVLAR®:
5X MORE ABRASION-RESISTANT
KEEPS ITS MECHANICAL PROPERTIES (INCLUDING COLOR) 10X LONGER AGAINST UV EXPOSURE.
BOLID'STER jeans are made with ARMALITH, a genius "architexture" that integrates its technology within the fabric itself, not just within the garment.
It is obtained by combining cotton fibers with UHMWPE fibers, previously used only in aerospace, military, and off-shores areas.
Contrary to other composite materials like a surfboard or an airplane wing, ARMALITH is flexible, soft, hydrophilic, light and dyed with a beautiful indigo color that will fade with time.
Technically-speaking: composite fabric means that the engineer can choose the reinforcement material (here UHMWPE) regardless from the matrix composite (here cotton).
Many patents have been registered regarding fabric architecture and therefore allow endless options for fabric combinations. Why UHMWPE then?
UHMWPE is the lightest of all performance fibers. Its density (0.95) enables the fabric to float while other material’s density is over 1.6. Steel represents a density of 7.
UHMWPE has unique properties; it is strong and resistant enough to be used in bulletproof jackets (previously manufactured from KEVLAR), in mooring lines for offshore platforms (made from steel in the past), military armors, or spacecraft tether…
Understanding the mechanics of abrasion and what contributes to abrasion resistance in concrete is hard. In general, materials having a good resistance to compression perform better. For protection gloves in workwear industry, standards have been created in order to compare different materials (see the below charts). UHMWPE is from far the best material compared to other fibers - or even leather.
High-performance fabrics do have their weaknesses. For example, long exposure to ultraviolet rays will cause loss of performances in KEVLAR fibers. This phenomenon will be emphasized if the moisture level rises. Shall we put our trust in a fiber – originally developed for our protection – if it loses its properties when exposed to the sun, or when washed? UHMWPE provides 0% moisture retention. Therefore, the fiber keeps its performances despite UV exposures, sweat and cleaning cycles.
