C0 Waterproofing

April 6, 2023

As more people become aware of the impact that traditional manufacturing methods have on the environment, they are looking for alternatives that are more sustainable. We are here for it! One of the latest innovations in eco-friendly outdoor clothing is the use of C0 water resistant treatment. In this blog, we'll take a closer look at what C0 water resistant treatment is, why it's a great choice for technical outdoor clothing, and which HIMALI products use this treatment to maximize performance while minimizing harm to our environment.

What is C0 water resistant treatment?

C0 water resistant treatment is a new type of water resistant treatment that is used on outdoor clothing. It's called "C0" because it does not contain any perfluorinated chemicals (PFCs), which are harmful to the environment. PFCs are commonly used in traditional water resistant treatment treatments because they are highly effective at repelling water. However, they are also persistent and can accumulate in the environment, causing long-term harm to wildlife and ecosystems.


C0 water resistant treatment is made using a new type of technology that eliminates the need for PFCs. This technology uses a special coating that is applied to the surface of the fabric that helps it to shed water. The C0 water resistant coating is made up of millions of microscopic pores that are smaller than water droplets. This means that water is repelled from the fabric, but air can still pass through, allowing enhanced breathability while remaining water resistant.

Why choose C0 water resistant treatment?

There are several reasons why C0 water resistant treatment is a great choice for technical outdoor clothing. First, it is eco-friendly. By choosing C0 water resistant treatment, you can reduce your impact on the environment and feel good about the choices you're making. Second, it is highly effective at repelling water. This means that you can stay dry and comfortable even in the wettest conditions. Finally, it is durable and long-lasting. C0 water resistant treatment can withstand multiple washes and wear, making it a great investment for anyone who loves the outdoors.


Disclaimer: C0 water resistant treatment is a treatment that is applied to either a fabric or insulation. Since it is a treatment and not a part of the fabric itself, that means it does degrade over time. The good news is that you can reapply this water resistant coating with specialized products like Nikwax. We sell them directly on the HIMALI website as well so you can add them to your order. In addition, even when the C0 water resistant coating is freshly applied, unless the garment is seam taped water can still penetrate the garment through the tiny holes in the fabric that are created along the seams. If you are looking for something waterPROOF, make sure that you are looking at a 3 Layer Hardshell, like our Monsoon Hardshell Collection.

Eco-friendly down jackets with C0 water resistant treatment.

Down Jackets are hugely popular for a reason. Light, warm, and highly packable, they are a staple in any mountaineering kit. However, when down gets wet it can become a breeding ground for bacteria, and when it gets soaked it loses all of its insulating properties (learn more about that here).

Traditional down jackets are often treated with PFCs to make them water resistant, however there are C0 options that are currently available! Eco-friendly down jackets with C0 water resistant treatment use HyperDry Down technology, which is similar to the C0 water resistant treatment used on other outdoor clothing. The HyperDry Down technology repels water from the down feathers, keeping you warm and dry even in damp conditions.

While HyperDry Down does offer additional protection against moisture, if you are looking for something waterPROOF, make sure that you are looking at a 3 Layer Hardshell, like our Monsoon Hardshell Collection.

Conclusion

C0 water resistant treatment is a great choice for anyone who loves the outdoors and wants to make more eco-friendly choices. By choosing C0 water resistant treatment, you can stay dry and comfortable while reducing your impact on the environment. Eco-friendly down jackets with C0 water resistant treatment are a great investment for anyone who wants to stay warm and dry while getting outside. Next time you're in the market for outdoor clothing, consider choosing products with C0 water resistant treatment and do your part to protect the environment.
