Frequently Asked Questions
What is OSM Shield?
OSM Shield is a trade secret protected fabric treatment process. This proprietary treatment process will transform any natural or synthetic fabric, garment, or yarn into becoming highly water resistant, stain resistant, and odor resistant for the useful life of a garment, without changing the inherent texture, comfort, or breathability of the fabric. OSM Shield also improves abrasion resistance, colorfastness to light, laundering, and crocking.
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-based, PFC-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.
Where do you convert the fabric?
The company 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?
The treatment process is typically around $1.00 per 60” running yard.
Does OSM Shield make finished garments?
Yes, OSM Shield has offices in both Shanghai and Bangladesh that handle the sourcing of fabrics and finished garment production. By combining conversion services with finished garment work, the customer can expect to reduce the overall cost of the treated/finished garment.
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?
- 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
- 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
- Effective repellency properties
- Vary in price
- Cumbersome supply model
- Potential health risks with PFOS and PFOAs
- Not as durable as OSM Shield
Do you have test results to back up your claims?
OSM Shield fabrics have been tested for breathability, vapor diffusion, water repellency, abrasion, colorfastness, and hot washing tests. The following testing standards have been used:
