Frequently Asked Questions

What is OSM Shield?

OSM Shield high performance fabric finishes are a combination of plant-based, PFOA-free, PFOS-free, and does not contain any PFC’s in excess of the industry accepted “allowable trace.” These chemistries can be applied to fabrics and yarns with proprietary and customized application processes to achieve unprecedented performance and durability.

OSM has a toolbox of chemistries that deliver extraordinary moisture repellency, stain resistance, stain release, and odor resistance without changing the inherent comfort, hand feel, or breathability of the fabric. These high-performance finishes can be applied to any type of fabric or fabric blend and are durable for the useful life of the fabric.

How exactly does OSM Shield work?

OSM Shield is a durable low surface energy fiber micro infusion process that transforms the fiber and fabric so it will not absorb moisture, stains, or odor. This is all accomplished without compromising the breathability or feel of the fabric.  Wash the treated fabric, garment, or yarn 50+ times and it performs just as well.

  • Once treated with OSM Shield, and after 50+ commercial hot washings and drying cycles, a typical 65/35 poly cotton blend fabric, garment, or yarn will repel water 85 times better than it would if left untreated.

  • OSM Shield can make a 100% cotton woven material water-resistant enough to pass the U.S. Custom’s Harmonized requirements for rainwear.

  • The Molecular Sciences and Engineering Team from the U.S. Army Natick Soldier Research Center verified that the breathability of a fleece, denim, or cotton t-shirt remains virtually unchanged after being treated with OSM Shield.

What types of fabric, garments, or yarn does OSM Shield work on?

A wide range of single layer natural and synthetic fabrics, garments, and yarn including, but not limited to: cotton, fleece, recycled, hemp, knits, polyester, bamboo, wool, polyester/cotton blends, denim, multiple blend fabrics, and others. To date, the company has not identified a fabric blend, garment, or yarn that cannot be successfully treated with OSM Shield.

Is OSM Shield "green friendly" ?

Yes. All OSM Shield chemistry is plant-basedPFC-Free, PFOS-Free and PFOA-Free. This ensures that the OSM Shield chemistry meets very stringent consumer safety requirements and provides consumer confidence worldwide. The formulation can be poured down the drain of a common household sink. Furthermore, fabrics treated with OSM Shield require far less wash cycles and have greatly reduced drying time, resulting in energy savings. OSM Shield works perfectly on natural renewable fibers and fabrics, minimizing the consumption and use of petroleum based synthetic fabrics. See more about OSM Shield’s Clean Chemistry HERE.

Where do you convert the fabric?

OSM Shield currently has conversion facilities in Asia and the United States.

Is OSM Shield only applicable to bulk fabric or can finished garments be treated?

OSM Shield does have the ability to treat finished garments.

How does OSM Shield fight odor?

OSM Shield has a healthy and environmental way to fight odor. See video below for more information:

How long does the conversion process take and what are the mechanics of processing an order?

The customer either supplies OSM Shield with the fabric of their choosing or contracts OSM Shield to source the fabric to be converted. Once the fabric is at the conversion facility, the order can be processed in days and shipped to the customer’s finished garment factory. Fabric conversion can take place at the customer’s conversion facility or one of OSM Shield’s conversion facilities. OSM Shield also has the capability to convert finished garments.

How much does OSM Shield add to the cost of the fabric?

All fabrics are different. OSM Shield has a toolbox of chemical recipes that are tailored to different kinds of fabrics depending on desired performance attributes. Contact us to get a quote on your fabric!

Is OSM Shield the same as a DWR (Durable Water Repellent)?

No, a DWR coats the outer surface of the fibers and can in turn affect the “hand” or feel of the fabric. DWR’s are also not resilient to washing or abrasion.

Why is OSM Shield different from other technologies in the marketplace?

OSM Shield

  • Applicable to all single layer fabrics tested to date

  • Highly water resistant, stain resistant, and odor resistant

  • Bacteria resistant

  • Abrasion resistant

  • Improves colorfastness to light, laundering, and crocking

  • Does not impact the breathability of the garment

  • Cost effective

  • Does not affect the “handle” or feel of the fabric

  • Customized treatment of the customer’s fabric of choice

  • Builds finished garments

  • Straight forward supply model

DWR (Durable Water Repellent)

  • Can alter hand or feel of garment

  • Does not stand up to washes or abrasion

  • Relatively inexpensive and readily available


  • Membrane of fabric between other layers of fabric used in a garment

  • Very waterproof

  • Not very breathable or vapor diffusive

  • Not applicable to single layer garments or natural fabrics

  • Expensive

  • Not comfortable against the skin

  • Not applicable to custom conversion work when the goal is to treat a customer’s fabric of choice

  • Basically a PU coating over Teflon patented membrane — not much different than hundreds of other PU coated rainwear

 100% waterproof rainwear

  • Typically PU or PVC coated

  • Does not breath

  • Does not feel comfortable against the skin

  • Not conducive to natural fabrics

Fluorocarbon Finishes

  • Effective repellency properties

  • Vary in price

  • Cumbersome supply model

  • Potential health risks with PFOS and PFOAs

  • Not as durable as OSM Shield
