What are BOLID'STER Jeans made of?

BOLID'STER jeans are made with ARMALITH2.0, 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 - ARMALITH2.0 is flexible, soft, hydrophilic, lightweight, 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. 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.


Because of this integrated fabric technology, BOLID'STER jeans are able to offer serious protection from a single, comfortable layer of material - a world's first for denim.
