In our packrafts, we use high-tenacity (HT) nylon with a TPU coating applied only on the inside, instead of traditional double-sided PVC-coated fabric. This solution delivers measurable, real-world performance advantages in demanding terrain.

1️⃣ Structural Strength

HT nylon is a densely woven fiber with enhanced tensile and tear strength.

• high resistance to cuts and point stress
• better force distribution across the fiber structure
• reduced risk of sudden material failure

The internal TPU coating ensures airtightness without stiffening the outer structural layer.

2️⃣ Behavior on Impact

How the material reacts when hitting rocks or roots matters.

• HT nylon has a smooth surface — it tends to slide over obstacles.
• PVC is stiffer and can “catch” on sharp edges, increasing tear risk.

3️⃣ Abrasion Resistance & Flexibility

TPU:

• more flexible than PVC
• handles repeated bending better
• retains performance in low temperatures

PVC:

• becomes rigid in cold
• may crack after repeated bending
• shows fatigue faster

4️⃣ Weight & Packability

• lighter at equal strength
• more compact when packed
• less rigid in use

5️⃣ Durability & Repairs

• supports reliable thermal welding
• creates strong, flexible seams
• does not become brittle over time like PVC
