Are you wondering what the difference is between DTRS75 fabric and our new D50T fabric and how it also compares to Dyneema?
First, they are all laminated, waterproof fabrics. Our new D50T fabric is made by Challenge Sailcloth. The same company that makes Ultra fabric and Ecopak fabric.
Advantages of D50T over DTRS75 fabric.
- Improved lamination layer
- Improved adhesive layer
- Quieter in use
- Better printing quality
- Better wear over time
- Weight is about the same
- Slightly lower cost
Tensile strength tests for D50T and DTRS75
Both fabrics are almost identical in strength.
How does Challenge D50T fabric compare to Dyneema?
There is no doubt that Dyneema is stronger. In fact, 1.0 Dyneema is about 4 times stronger (tensile strength) than D50T when you only look at the data.
In the case of dry bags, stuff sacks, and food bags.... in most backpacking usage situations we would argue it doesn't need to be that strong and you cab save some hard earned money. While Dyneema's tensile strength is extremely strong, it is still prone to punctures and small holes. That's where lightweight fabrics like D50T, with an outside WOV layer to protect it, come in handy.
Are they waterproof?
Yes, all fabrics on this page are laminated waterproof fabrics.
Cost difference between D50T and Dyneema
The end product is about 25-50% lower in cost than the same Dyneema product in most cases.
Weight difference of D50T and Dyneema
D50T is substantially lighter than 2.92 Dyneema and is only slightly heavier than Dyneema 1.43.
Is D50T good for backpacks?
Maybe.. You may see us use this fabric in backpacks very soon. We have several test backpacks made in D50T fabric and they have held up great. Once we are done testing we shall see.
