We've teamed up with Toray to use the innovative Torain® 3D 2.5 Layer Waterproof Breathable Lamination Technology in the Tushar Rain Jacket.
What this means is that you get a more breathable & durable rain jacket with less weight.
This technology consists of a few main innovations:
- Body-Mapped Waterproof Membrane Laminations
- 3D Printed Interior Half Layer
- Torain® Materials & Seam Tapes
Many rain jackets rely heavily on DWR treatments on the face fabric & use a breathable hydrophilic waterproof membrane beneath.
DWR treatments eventually will wear away.
Once a DWR (Durable Waterproof Repellent) treatment is gone, the hydrophilic membrane in these jackets is what keeps them waterproof.
Hydrophilic membranes basically absorb water until the membrane is saturated. This causes it to swell and seal. At this point, water will not be able to pass through the membrane.
The only problem with this is that a saturated hydrophilic membrane feels cold and clammy to the touch, and no longer can breathe (allow vapor to pass through.)
Hydrophobic membranes by nature repel water by themselves instead of absorb it like a hydrophilic membrane would. Even when the DWR treatment wears off the face fabric of a jacket, no water will be absorbed.
This means that hydrophobic membranes are more durable (in terms of getting "wetted out") and have a higher waterproof rating.
The only downside with using only hydrophobic waterproof membranes in a rain jacket is that they are not very breathable.
This causes the moisture vapor from your body to stay trapped inside the rain jacket, resulting in you getting soaked from the inside.
Tushar Rain Jacket Body Mapped Application
The Tushar Rain Jacket uses both hydrophilic membranes and hydrophobic membranes.
We've placed these membranes exactly where you'll need them for higher durability without sacrificing breathability.
The gray panels of the Tushar Rain Jacket are where we've used hydrophobic membranes. These are high stress areas like your shoulders and back where a backpack might wear away the DWR treatment more quickly or where rain falls most directly.
The colored panels of the Tushar Rain Jacket are where we've used a hydrophilic membrane. Again, hydrophilic membranes are more breathable than hydrophobic, and will keep your body comfortable and help you avoid that cold clammy feeling.
These colored hydrophilic areas of the Tushar Rain Jacket receive less abrasion, and there is less risk of the DWR treatment wearing down very quickly.
By body-mapping these waterproof membranes, we've maximized both durability and breathability so you can comfortably wear the Tushar Rain Jacket all day as needed!
3D Printed Interior Half Layer
Most Jackets have 3 layers:
- Face Fabric
- Waterproof Membrane
- Interior Layer (next to skin)
The Tushar Rain Jacket only has 2.5 layers!
This is because of Torain® 3D Print fabric technology. This interior half layer has 2 basic functions:
- significantly reduce the weight of the rain jacket (thus allowing us to use a stronger 20D face fabric rather than 7D in comparable jackets)
- keep the waterproof membrane off of your skin so you don't feel "clammy"
Basically we've cut the weight of the jacket by a whole half layer & have made it more comfortable at the same time!
This lighter interior layer allowed us to beef up the face fabric thickness so you can still have an ultralight rain jacket that weighs just ounces, but it will be MUCH stronger than comparable 7 oz ultralight rain jackets by other brands.
Torain® Materials & Seam Tapes
All of the materials used in the Tushar Rain Jacket are sourced through Toray. Toray has developed their own seam tape that adheres to their fabrics much better, as is proven in the Jungle Test
The Jungle Test
The Jungle Test is a simulator that mimics time & use in humid, saline environments.
This is important, because inside a rain jacket your body creates a micro-environment that is very humid and very saline (salty) from sweat & regular body moisture.
Not only does a rain jacket have to hold up to outside weather, but it has to be able to handle your internal micro-environment as well.
When a product or garment is place in the Jungle Test simulator, the test is to see how well that product holds up before deteriorating. 1 week is the equivalent of 1 year non-stop in a humid, wet, saline environment.
The Tushar Rain Jacket successfully handled the equivalent of 10 years of non-stop exposure without any signs of seam degradation!
While other products were starting to fall apart and the seam tape was coming loose, the Torain® fabrics and seam tape held together exceptionally well.
To sum this up, the Tushar Rain Jacket is built better & can handle the extreme environments on your adventures for many years to come!
