A. No. Kevlar fibers are actually stronger than Duralite. However, we have found our Souris River Duralite rental canoes to hold up equally as well as our Souris River Kevlar rental canoes. When one compares kevlar canoes made by other canoe companies using the usual polyester resins found throughout the canoe-building industry, Souris River Duralite canoes are, without a doubt, much, much tougher than those OTHER conventional, Kevlar canoes. In some cases, they are almost as light or lighter than those other well-known canoes and much more affordable! From durability to price, Souris River Duralites easily put those other conventional Kevlar canoes to shame.
