Choosing the right packraft isn’t just about brand or looks—the tube material determines how light, durable, and high-performing your boat will be. Knowing the trade-offs can help you select the perfect boat for your adventures.
1. Thread Thickness (Denier)
The denier (d) measures fabric weight per unit length, impacting strength and rigidity:
-
1000-d PVC – Very tough but heavy (Kokopelli Recon, XPD).
-
420-d Nylon – Increased stiffness and abrasion resistance (Alpacka Forager, Wolverine Self Bailer). Moderate weight penalty (~6–8 oz).
-
210-d Nylon – Balanced durability and weight (Alpacka Standard, Kokopelli Nirvana, MRS Alligator).
-
70-d Nylon – Ultralight but less durable (Supai Canyon, Kokopelli Hornet Lite).
Thicker threads give more strength but add weight. For river-running, 210-d nylon is the popular choice.
2. Coatings Matter
Most nylon packrafts have urethane coatings for air retention and abrasion resistance:
-
Thicker coating → more durable but heavier.
-
Thinner coating → lighter but less protective.
Other materials like PVC or Vectran behave differently. PVC is heavy but tough; Vectran is strong with minimal stretch but more expensive.
3. Weight vs. Durability
Consider your adventure style:
-
Whitewater paddling – Heavier, stiffer boats (420-d or 210-d) improve handling and durability.
-
Backpacking & long portages – Lighter 70-d boats are easier to carry but need extra care.
The 420-d Wolverine Self Bailer offers added rigidity and durability at a modest weight increase (~8 lbs), ideal for challenging rivers.
4. Performance
Material affects water handling:
-
Stiff tubes → better tracking, faster response.
-
Soft, light tubes → forgiving on rocks or shallow rivers but may feel slower.
5. Conclusion
Choosing the right packraft material is all about balancing weight, durability, and performance:
Material / Denier | Weight | Durability | Performance |
---|---|---|---|
1000-d PVC | Heavy | Excellent | Rigid, high tracking |
420-d Nylon | Moderate-heavy | Very good | Stiff, responsive |
210-d Nylon | Moderate | Good | Balanced |
70-d Nylon | Light | Lower | Flexible, forgiving |
Your adventure style—whether whitewater rivers or long-distance hiking—should guide your choice.
