What is Dyneema® and why do we use it over Kevlar®?
Our initial goal was to develop a single layer fabric that would exceed the CE-13595 Protective Motorcycle Apparel Standards in place at the time, however this proved a real challenge using Kevlar®.
To achieve our goal meant going deeper, and it was during this research phase that we discovered the world’s strongest fibre: Dyneema®. Dyneema® is a trademarked brand name of ultra-high molecular weight polyethylene (UHMWPE)— a high-density material that can be spun like cotton and feels great to wear. Dyneema® gave us the strength and abrasion resistance we required while allowing our jeans to look and feel like regular denim.
Dyneema was the key to unlocking our vision of an AA-rated PrEN 17092-1:2017 single-layer fabric for abrasion resistance. Instead of placing bulky layers and liners into our jeans, we wove Dyneema® fibres into the warp and weft of our denim to create a completely single-layer protective fabric that looks and feels just like regular denim.
Seam strength is another important factor in ensuring protective garments keep you safe – there’s no point having the world’s toughest denim if it all falls apart at the seams! SA1NT denim seams are tested using a tensile testing machine which pulls the seam apart and measures the force required for a break to occur.

For motorcycle garments to meet the new European EN17092 Class A, AA, AAA safety standards, impact protection armour must be present within the garment and must be positioned to cover the appropriate body part relevant to the impact protector. For motorcycle jeans, this includes armour to protect the knees and hips.
This same test is used for the fabric itself with samples of the fabric essentially being pulled apart until failure. Tests are conducted along both the warp and weft of the fabric to ensure strength is retained in all directions.
